Agricultural Glossary

ADG (Average Daily Gain) Livestock & Dairy

The weight a beef animal or hog gains per day on a given ration. Feedlot operators track ADG closely because it drives cost-of-gain math — the cheaper the added pound, the better the margin at sale time.

Agribusiness Finance

The combined sector of farming, food processing, input supply, equipment manufacturing, and agricultural distribution. Used more often in business, policy, and academic contexts than by working farmers themselves.

Agricultural subsidies Regulation

Government payments to farmers, typically administered through the Farm Bill — commodity payments, crop-insurance premium subsidies, conservation cost-share, disaster assistance. A persistent feature of U.S. farm policy since the 1930s.

Agroforestry Crops & Planting

A land-use system that deliberately integrates trees or shrubs with crops or livestock — alley cropping, silvopasture, windbreaks, riparian buffers. Practiced for soil health, biodiversity, and diversified income.

Agronomy Crops & Planting

The science of soil management and field-crop production. An agronomist studies how plants, soil, water, weather, and management practices interact to produce food, fiber, and fuel.

Alfalfa Crops & Planting

A high-protein legume grown primarily as hay for dairy and beef cattle. A well-managed alfalfa stand can produce three to five cuttings per year and last four to seven years before reseeding.

Animal Unit Month (AUM) Regulation

A standardized measure of grazing — the amount of forage one mature cow with calf (or equivalent) consumes in a month. Used by USDA, BLM, and state grazing authorities to price leases and allocate rangeland.

Auger Machinery

A rotating helical screw used to move grain from one location to another — most often from a combine or grain cart into a truck, wagon, or bin. Augers are sold by diameter and length, and matched to the flow rate a farm actually needs.

Auto-steer Precision Ag

A GPS-guided system that steers a tractor or combine along a pre-planned path while the operator monitors. Reduces overlap, driver fatigue, and fuel use; it was the entry point for most farms into precision agriculture.

Baler Machinery

A machine that compresses cut hay, straw, or silage into bales — round or square, wrapped in twine, net, or plastic. Round balers dominate most hay operations; big square balers show up on larger commercial forage farms. (Crest Capital: hay baler financing.)

Beef cattle Livestock & Dairy

Cattle raised for meat, as distinct from dairy cattle raised for milk. Common U.S. beef breeds include Angus, Hereford, Charolais, and Simmental. Operations typically specialize in cow-calf, stocker, or feedlot phases.

Bin (grain bin) Machinery

On-farm storage for harvested grain — typically a round steel structure with aeration fans and moisture monitoring. Bin storage lets a farmer hold grain off the cash market and sell when prices are better.

Broadcast seeding Crops & Planting

Scattering seed across a field surface without placing it in a furrow. Faster and cheaper than drill-seeding; less precise on spacing and depth. Common for pasture, cover crops, and some small-grain work.

Broiler Livestock & Dairy

A chicken raised specifically for meat, usually marketed at five to nine weeks old. U.S. broiler production is dominated by vertically integrated contracts between growers and large processors.

CAFO (Concentrated Animal Feeding Operation) Regulation

An EPA classification for livestock operations above specific size thresholds that confine animals on small land areas. CAFOs face federal water-quality and manure-management permit requirements under the Clean Water Act.

Capital lease Finance

A lease structure that transfers most of the risks and benefits of ownership to the lessee — treated like a purchase for tax and accounting purposes. Contrast with an operating lease, which is closer to a rental.

Center pivot Soil & Water

An irrigation system that rotates around a central water source, watering a circular field. Those green circles visible from an airplane over the Great Plains are typically center pivots. Pivot length typically runs a quarter-mile to half-mile. (Crest Capital: irrigation systems financing.)

Combine Machinery

A machine that harvests grain crops by combining three operations in one pass: reaping (cutting), threshing (separating grain from stalk), and winnowing (separating grain from chaff). The single largest equipment purchase on most row-crop farms. (Crest Capital: combine financing.)

Compensating balance Finance

A minimum balance a bank requires a borrower to keep on deposit as a condition of a loan. Effectively raises the loan’s real cost because the balance can’t be used elsewhere. Worth scrutinizing in any bank equipment financing offer.

Conservation Reserve Program (CRP) Regulation

A USDA program that pays farmers to take environmentally sensitive land out of row-crop production and plant species that improve soil and water quality. Contracts typically run 10 to 15 years.

Cover crop Crops & Planting

A non-cash crop planted between cash-crop cycles to cover the soil. Common choices: cereal rye, crimson clover, tillage radish. Used to reduce erosion, build organic matter, suppress weeds, and fix nitrogen.

CSA (Community Supported Agriculture) Finance

A direct-marketing model where customers buy a share of a farm’s harvest in advance, then receive weekly or biweekly distributions during the growing season. Shifts some production risk from farmer to consumer.

Cow-calf operation Livestock & Dairy

A ranch that maintains a breeding herd of cows and sells the weaned calves to stocker or feedlot operations. Cow-calf is the pasture-based, long-cycle end of the beef supply chain.

Crop insurance Finance

Federally subsidized insurance that protects growers against crop yield or revenue losses. Multi-Peril Crop Insurance (MPCI) is the most widely used form. Required on many FSA-guaranteed loan programs.

Crop rotation Crops & Planting

Planting different crops in a planned sequence on the same field — commonly corn/soybean in the Midwest. Breaks pest cycles, improves soil, and manages nutrient use. The classic counter to monoculture.

Cull Livestock & Dairy

To remove an animal from the breeding herd — typically because of age, poor performance, reproductive failure, or health issues. Cull cows often go to ground-beef processing; cull dairy cows become beef cattle in effect.

Cultivar Crops & Planting

A plant variety developed through controlled breeding or selection, distinct from naturally occurring wild types. "Pioneer P1197AM" is a corn cultivar; "Silver Queen" is a sweet-corn cultivar.

Cultivator Machinery

Tillage equipment used to break up soil, uproot weeds, and prepare a seedbed without inverting the soil as fully as a plow does. Field cultivators cover secondary tillage on most Midwest grain operations.

Dairy Livestock & Dairy

The production of milk and milk products from lactating animals, primarily Holstein and Jersey cattle in the U.S. Equipment needs span milking parlors, bulk tanks, cooling systems, and manure handling. (Crest Capital: dairy machinery financing.)

Disc harrow (or disk) Machinery

A tillage implement with rows of concave steel discs that cut and mix the top several inches of soil. Used to chop crop residue, level a field, and prepare a seedbed. Heavy offset discs can do primary tillage.

Double-cropping Crops & Planting

Planting and harvesting two crops from the same field in one growing season — typically winter wheat followed by soybeans in the Mid-Atlantic and lower Midwest. Compresses the season and raises risk but can lift whole-field revenue.

Drill (grain drill) Machinery

An implement that places seed at a controlled depth and spacing in narrow rows. Differs from a planter in that drills are typical for small grains, forages, and cover crops; planters handle row crops like corn and soybeans.

Drip irrigation Soil & Water

An irrigation method delivering water slowly to the root zone through a network of emitters. Most water-efficient method available — common on orchards, vineyards, and specialty crops; higher upfront cost than pivot or flood.

Drone (UAV) Precision Ag

Unmanned aerial vehicles used for field scouting, aerial imagery, multispectral crop-health analysis, targeted spraying, and livestock monitoring. The FAA regulates commercial ag drone use under Part 107; larger spray drones fall under a separate Part 137 exemption.

Drought Soil & Water

An extended period of below-normal precipitation severe enough to harm crops, livestock, or water supplies. USDA and NOAA classify droughts into categories (D0 through D4) on the weekly U.S. Drought Monitor.

EQIP (Environmental Quality Incentives Program) Regulation

A USDA NRCS cost-share program that pays farmers and ranchers to implement conservation practices — cover crops, fencing, irrigation upgrades, nutrient management. Often paired with FSA loan programs on the same project.

Erosion Soil & Water

The wearing away of topsoil by wind or water — one of the foundational problems conservation tillage, cover crops, and terracing try to solve. The 1930s Dust Bowl is the canonical U.S. example.

Farm Bill Regulation

A comprehensive omnibus law reauthorized roughly every five years that sets U.S. agriculture, nutrition, and rural-development policy. Covers crop insurance, commodity programs, conservation, SNAP, and FSA loan programs.

Farm Credit System Finance

A federally chartered network of borrower-owned cooperative lenders serving U.S. agriculture and rural communities. Competes with commercial banks and equipment finance companies on farm real-estate and operating loans.

Farm operating loan Finance

Short-term financing used to cover production costs — seed, fertilizer, fuel, labor — repaid after harvest or livestock sale. Usually structured around the crop or production cycle, not a fixed monthly schedule.

Farrow-to-finish Livestock & Dairy

A pork operation that handles the full production cycle — from breeding and birth (farrowing) through growing and finishing for market. Contrast with specialized wean-to-finish or finish-only contract operations.

Feedlot Livestock & Dairy

A confined operation that finishes cattle (or other livestock) on concentrated rations of grain and silage to reach slaughter weight. Most U.S. feedlot capacity is concentrated in Nebraska, Kansas, Texas, and Colorado.

FMV lease Finance

A lease structure where, at end of term, the lessee can return the equipment, renew the lease, or buy it at its then fair market value. Lower monthly payments than a $1-buyout lease; ownership is optional.

Forage Crops & Planting

Plant material grown to feed grazing animals — includes hay, silage, pasture grasses, and some row crops like corn silage. The quality and quantity of forage drives beef and dairy production economics.

Forage harvester Machinery

A machine that cuts forage crops (corn, alfalfa, grass) and chops them into small pieces for silage storage. Self-propelled forage harvesters are among the most expensive pieces of ag equipment a dairy will own.

FSA-guaranteed loan Finance

A loan made by a commercial lender (bank, credit union, or equipment finance company) with partial repayment guarantee from the USDA Farm Service Agency. Guarantees let lenders extend credit to borrowers who’d otherwise be marginal.

Futures contract Finance

A standardized agreement to buy or sell a commodity at a set price on a future date. Grain, livestock, and dairy producers use futures contracts (traded on CME / CBOT) to lock in prices before delivery — the core building block of agricultural hedging.

Furrow Soil & Water

A narrow trench cut into a field, either for planting seed at a controlled depth (by a drill or planter) or for directing irrigation water down a field (furrow irrigation).

Gestation Livestock & Dairy

The pregnancy period from conception to birth. Roughly 283 days (nine months) for cattle, 114 days for swine, 147 for sheep. Cash-flow planning on breeding farms runs on these cycles.

Germination Crops & Planting

The emergence of a seedling from a seed. Germination rate (the percentage of seeds that actually sprout) is a key quality measure on seed labels and determines planting density.

GPS guidance Precision Ag

Using satellite positioning to guide tractors, sprayers, or combines along precise field paths. The foundational technology underneath auto-steer, section control, and variable-rate application.

Grain Crops & Planting

The edible seed of a cereal grass or pulse crop — corn, wheat, soybeans, sorghum, rice, oats, barley. "Grain farming" generally refers to row-crop production of these commodities at scale.

Green manure Crops & Planting

A cover crop grown specifically to be tilled or terminated back into the soil to add organic matter and nitrogen. Common green manures: crimson clover, hairy vetch, field pea.

Grid sampling Precision Ag

A soil-sampling method that divides a field into grid cells and takes composite samples from each. Feeds into variable-rate fertility recommendations that apply different nutrient rates across the field.

Harvester Machinery

A general term for a machine that harvests a crop. Combines harvest grain; specialty harvesters exist for cotton, sugar cane, tree nuts, grapes, blueberries, and other crops. The correct harvester for a given crop is often the most specialized — and most expensive — piece of equipment on the farm.

Header Machinery

The front attachment of a combine that cuts and feeds crops into the threshing mechanism. Different headers handle different crops: corn headers, grain platforms, draper headers, pickup headers for windrowed crops.

Hedging Finance

Using futures, options, or forward contracts to lock in a price and reduce exposure to commodity swings. A grain farmer who sells December corn futures in August is hedging against a price drop between planting and harvest.

Heifer Livestock & Dairy

A young female cow that has not yet produced a calf. Once she does, she’s a cow. Replacement heifer is the term for young females retained to enter the breeding or dairy herd.

Hitch (3-point) Machinery

The standardized three-arm linkage on the back of a tractor that attaches and lifts implements (mowers, tillers, box blades). Harry Ferguson’s 1930s design that became the worldwide standard.

Horsepower Machinery

The measure of a tractor or engine’s power output. Tractor specs typically list engine horsepower and PTO horsepower separately. PTO horsepower — power available to run an implement — is the figure that matters for matching a tractor to a job.

Hybrid seed Crops & Planting

Seed produced by controlled cross-pollination of two distinct parent lines, yielding offspring with improved vigor, yield, or specific traits. Most U.S. corn is grown from hybrid seed; farmers buy new seed each year because hybrid seed doesn’t breed true.

Hydroponics Crops & Planting

Growing plants in nutrient-rich water without soil. Common for greenhouse tomatoes, leafy greens, and herbs. Higher yield per square foot than field production; higher energy, water-quality monitoring, and equipment costs.

Implement Machinery

Any attachable piece of equipment pulled or mounted by a tractor: planter, baler, cultivator, mower, sprayer, wagon. "Implement dealer" is a traditional name for an ag equipment dealership.

Inoculant Crops & Planting

A preparation of beneficial bacteria (most often Rhizobium) applied to legume seed to encourage nitrogen fixation in the soil. Alfalfa, soybean, and clover plantings are typically inoculated at planting.

ISOBUS Precision Ag

An industry-standard communication protocol (ISO 11783) that lets tractors and implements from different manufacturers talk to each other through a single in-cab display. The equipment-world equivalent of USB.

Lactation Livestock & Dairy

The period during which a cow produces milk. A dairy cow’s standard lactation is about 305 days, followed by a 60-day dry period before the next calving.

Legume Crops & Planting

A plant family (Fabaceae) that includes soybeans, alfalfa, clovers, peas, and beans — notable for hosting nitrogen-fixing bacteria on the roots. Legumes in rotation reduce the need for nitrogen fertilizer.

Livestock Livestock & Dairy

Domesticated animals raised for food, fiber, labor, or other products. In U.S. ag terminology, livestock usually means cattle, hogs, sheep, goats, and sometimes horses; poultry is typically tracked separately.

Loam Soil & Water

A soil texture that blends sand, silt, and clay in roughly balanced proportions — generally the most productive texture for row-crop agriculture. Adjectives like silty loam or clay loam describe which fraction dominates.

Loader Machinery

A front-mounted bucket and lift arms used to scoop, carry, and dump material. Tractor-mounted loaders are a near-universal fixture on beef, dairy, and mixed farms; skid-steer loaders handle tighter spaces.

Monoculture Crops & Planting

Growing the same crop in the same field year after year. Efficient in the short run, problematic over time because it tends to build up pests, deplete specific nutrients, and erode soil structure.

Mower Machinery

Equipment that cuts hay, forage, or pasture — sickle-bar, rotary disc, or disc-conditioner mowers are the most common. Mower conditioners crimp stems in the same pass to speed field drying.

Net farm income Finance

A farm’s gross revenue minus all operating expenses, including depreciation, interest, and hired labor. USDA’s Economic Research Service publishes net-farm-income forecasts quarterly; the number drives lender and policymaker views of the sector’s health.

Nitrogen (N) Soil & Water

A primary plant nutrient, required in large quantities by non-legume crops. Managed through fertilizer application, legume rotation, manure, and cover crops. The most expensive nutrient to replace on a row-crop farm.

No-till Crops & Planting

A planting system that leaves crop residue on the surface and places seed directly through it, without tillage. Reduces erosion and fuel use; requires different equipment (no-till drills, coulter-equipped planters) and different weed management.

NRCS (Natural Resources Conservation Service) Regulation

The USDA agency that provides conservation technical and financial assistance to farmers and ranchers. Runs EQIP, CSP, and most federal working-lands conservation programs.

Operating lease Finance

A lease structure where the lessee rents equipment for a period shorter than its useful life and returns it at end of term. Lower payments than a capital lease; no ownership at the end.

Organic farming Crops & Planting

Production under USDA’s National Organic Program standards — no synthetic fertilizers, restricted pesticide list, no GMOs, rotation requirements, and three years of transition before the "Certified Organic" label is granted.

Parlor (milking) Livestock & Dairy

The structure and equipment where dairy cows are milked — configured as herringbone, parallel, rotary, or robotic. Parlor design and capacity drive milking-time-per-cow and labor economics on a dairy. (Crest Capital: milking machine financing.)

pH (soil) Soil & Water

The measure of soil acidity or alkalinity on a scale of 0 to 14. Most row crops thrive between 6.0 and 7.0. Lime raises soil pH; elemental sulfur lowers it.

Phosphorus (P) Soil & Water

One of the three primary plant nutrients (the P in N-P-K). Essential for root development and energy transfer. Phosphorus runoff from farm fields is a major contributor to algal blooms in lakes and coastal waters.

Planter Machinery

Precision equipment that places individual seeds at specified spacing and depth in rows — contrast with a drill, which places seed in closer-spaced rows without the same per-seed precision. Modern corn planters run 12 to 48 rows. (Crest Capital: planting machine financing.)

Plow Machinery

A primary tillage implement that inverts soil, burying surface residue and weeds. Moldboard plows are the classic design; chisel plows leave more residue on top. Less common today as no-till has spread.

Poultry Livestock & Dairy

Domesticated birds raised for meat, eggs, or feathers — chickens, turkeys, ducks, geese. U.S. poultry production is the most vertically integrated of any major livestock sector.

Precision agriculture Precision Ag

A set of technologies that use GPS, sensors, satellite imagery, and variable-rate control to tailor farming inputs to site-specific field conditions. What once meant GPS auto-steer now encompasses variable-rate seeding, nitrogen modeling, AI-assisted scouting, and telematics.

PTO (Power Take-Off) Machinery

A splined shaft at the rear of a tractor that transmits engine power to an implement — baler, mower, rotary cutter, auger. Standard speeds are 540 and 1,000 rpm. PTO safety is one of the most important farm-safety topics to teach new operators.

Rake (hay) Machinery

Equipment that gathers cut hay into windrows for baling. Common types: wheel rakes, rotary rakes, and basket rakes. Critical to efficient dry-down and pickup by the baler.

Regenerative agriculture Crops & Planting

A set of practices aimed at rebuilding soil health, sequestering carbon, and improving watershed function — cover cropping, no-till, diverse rotations, integrated livestock grazing. Overlaps with organic and conservation ag but is not the same thing.

Row crop Crops & Planting

A crop planted in distinct rows wide enough for cultivation equipment to pass between — corn, soybeans, cotton, sorghum are the major U.S. row crops. Contrast with small grains and forages, which are planted in narrower rows or broadcast.

RTK (Real-Time Kinematic) Precision Ag

A high-precision GPS correction method that achieves sub-inch accuracy — the level required for repeatable strip-till, inter-row cultivation, and multi-year controlled traffic. Most farms subscribe to an RTK network rather than running their own base station.

Ruminant Livestock & Dairy

An animal with a four-chambered stomach that can digest fibrous plant material like grass and hay — cattle, sheep, goats, deer. The ability to convert forage into meat and milk is what makes ruminant agriculture economically workable.

Section control Precision Ag

Automated shutoff of individual rows or sections on a planter, sprayer, or fertilizer applicator to prevent overlap on headlands and in point rows. Typical payback: 4 to 8 percent input savings.

Section 179 deduction Finance

A U.S. tax-code provision that lets a business deduct the full cost of qualifying equipment in the year placed in service, rather than depreciating it over time. Deduction limits are set annually; check the current-year amount with a CPA before planning around it.

Silage Crops & Planting

Forage (usually corn or alfalfa) that has been chopped, packed, and fermented in an anaerobic environment to preserve it as livestock feed. Stored in bunkers, bags, or silos. Higher moisture and nutrient density than hay.

Skip-payment schedule Finance

A loan or lease repayment structure that omits payments in specific months — timed to a farm’s income cycle. Common on ag equipment financing where cash shows up at harvest or livestock sale, not evenly across the year.

Smart farming Precision Ag

A broad label for farm operations that use connected devices, data analytics, and decision-support software to inform crop and livestock management. Includes but extends beyond precision agriculture — IoT soil sensors, automated feeders, and farm-management software all fall under it.

Soil test Soil & Water

Laboratory analysis of a soil sample to measure pH, organic matter, and levels of macronutrients (N, P, K) and micronutrients. The foundation of every credible nutrient management plan. Extension services and private labs both offer the work.

Sprayer Machinery

Equipment that applies liquid herbicides, fungicides, insecticides, or fertilizers. Self-propelled sprayers with 100- to 120-foot booms are now standard on most Midwest row-crop farms; pull-type sprayers remain common on smaller operations.

Stocker Livestock & Dairy

A weaned calf grown on pasture or forage for a period (typically 4 to 10 months) before moving to a feedlot. Stocker operations bridge the cow-calf and feedlot phases.

Telematics Precision Ag

Cellular or satellite connectivity in a tractor or implement that streams location, engine data, fuel use, and operational metrics to a fleet dashboard. John Deere’s JDLink and Case IH’s AFS Connect are the best-known systems.

Term loan Finance

A loan repaid over a fixed period on a set schedule — typical for equipment purchases, facility construction, or land. Contrast with an operating loan, which is short-term and tied to a production cycle.

Tillage Crops & Planting

The mechanical manipulation of soil for weed control, residue management, and seedbed preparation. Conventional tillage moves a lot of soil; conservation tillage (including strip-till and no-till) leaves more residue on top to reduce erosion.

Total mixed ration (TMR) Livestock & Dairy

A livestock feed formulation that combines forages, grains, protein, minerals, and additives into a single balanced mix delivered to the feedbunk. Standard practice on most modern dairy operations; requires a TMR mixer wagon.

Tractor Machinery

The central power unit on most farms: a diesel (occasionally gasoline or electric) machine designed to pull, push, or power implements through a hitch, PTO, or hydraulic connection. Ranges from sub-compact utility units to articulated 600-plus horsepower row-crop giants. (Crest Capital: tractor financing.)

UCC filing Finance

A legal notice filed with a state (under the Uniform Commercial Code) that a lender has a security interest in specific collateral — equipment, inventory, livestock, crops. The standard way equipment financing gets secured on a farm.

USDA (U.S. Department of Agriculture) Regulation

The federal department with primary responsibility for farming, forestry, rural development, food safety, and nutrition. Major sub-agencies: FSA (Farm Service Agency), NRCS, APHIS, ERS, and the Forest Service.

Variable-rate application (VRA) Precision Ag

Applying different rates of seed, fertilizer, or crop-protection products across a field based on prescription maps tied to soil type, yield history, or topography. Aimed at matching input to need rather than averaging across the whole field.

Vertical farming Crops & Planting

Growing crops in stacked indoor layers under controlled lighting, temperature, and humidity. Most U.S. vertical-farm operations produce leafy greens or herbs; the business model depends on reducing transportation costs and year-round production relative to field agriculture.

Weaning Livestock & Dairy

Separating a young animal from its mother’s milk supply, transitioning it to solid feed. For beef calves, weaning typically happens at 6 to 8 months; for dairy calves, at 6 to 10 weeks.

Wheel line (irrigation) Soil & Water

A long, movable sprinkler irrigation line supported on wheels, rolled laterally across a field between watering positions. Less common than center pivots today, but still in use on smaller fields and specialty crops.

Windrower (swather) Machinery

A self-propelled machine that cuts and lays hay or small grain into rows (windrows) to dry in the field before baling or combining. Older usage calls the same machine a swather.

WOTUS (Waters of the United States) Regulation

The legal definition that determines which waters fall under federal Clean Water Act jurisdiction. The scope has been redefined multiple times by courts and regulators; affects farm permit requirements for drainage, wetlands, and discharge.

Yearling Livestock & Dairy

A young animal roughly one to two years old — common usage in cattle for animals in the stocker phase or young replacement heifers.

Yield monitor Precision Ag

A sensor system on a combine that measures grain flow and moisture continuously during harvest, producing a georeferenced yield map of the field. The raw data source for most precision-ag decision-making.
