Crop planning guide, August 2026
Compare crops before you plant
A useful crop comparison does not name a universal winner. It shows which crop fits your field constraints, rotation, operation, and market plan, then identifies the evidence you still need.
What a crop comparison should answer
No single score decides
The better crop is the one that fits the field and the farm business after you account for water, soil, timing, equipment, labor, buyers, and risk. A high reference yield or price cannot cancel a hard field constraint.
A useful comparison has a boundary
Regional comparison pages can screen a crop pair against representative conditions. They cannot measure your parcel, verify a buyer, or forecast your profit. Treat the result as a shortlist for field checks.
Browse crop comparisonsCompare field constraints first
Start with limits, not revenue
Use this screen to test whether each crop fits the same field and season. If one crop fails a material constraint, record the shortfall before comparing economics.
| Dimension | Question to ask | Evidence to collect |
|---|---|---|
| Climate | Does the season provide the crop's required heat and frost window? | Local weather record, elevation, planting date, and cultivar maturity. |
| Water | Can the field meet peak demand in a dry period? | Irrigation source, delivery rate, rainfall pattern, drainage, and storage. |
| Soil | Does the root zone support the crop without an unverified amendment plan? | Laboratory soil test, depth, pH, texture, salinity, and restrictive layers. |
| Operations | Can you plant, manage, harvest, store, and transport it on time? | Equipment, labor, planting and harvest windows, storage, and logistics. |
| Market | Who will buy the crop at the required grade and timing? | Buyer terms, quality requirements, delivery route, contract, and price basis. |
Soil tests still matter
A regional crop page cannot replace a laboratory soil test or field inspection. Do not turn a displayed pH, water need, or drainage label into a fertilizer, lime, or irrigation prescription.
Compare farm economics second
Reference values are not your budget
Use regional cost and return data to frame questions, not to publish a farm-specific profit. The USDA Economic Research Service reports that its commodity accounts are average estimates at regional or national levels and that production practices vary across farms.
Commodity costs and returns estimates may be considered as average estimates for production of agricultural commodities at regional or national levels.

Use break-even inputs
For a real decision, enter your expected yield, sale price, variable costs, land charge, labor, machinery, storage, financing, and risk assumptions in a transparent budget. Compare break-even yield and price, not just gross revenue.
Run your own scenario
Use the crop ROI estimator for editable assumptions, then compare the result with local records and buyer terms.
Use rotation and market evidence
The preceding crop changes the decision
Compare the crop pair within the actual rotation, not as isolated crops. Residue, nutrient credits, disease and pest cycles, planting timing, and equipment can change the next crop's cost and risk.
Crop rotations vary with soil type, crops produced, farming operations, and how the crop residue is managed.

Confirm the local market
USDA NASS Quick Stats can provide official statistics by commodity, location, and time period. It does not tell you whether a buyer will accept your grade or whether your logistics can reach the market. Confirm those terms locally.
Read the AgriAuditor comparison pages
Start with a regional screen
Each page below compares a pair against the same regional context. Read the soil and climate fields, reference yield and price fields, assumptions, source notes, and limitations together.
Iowa regional screen
A common field-crop comparison with different nutrient, rotation, and operational questions.
Iowa regional screen
A cool-season grain comparison where maturity, market outlet, and rotation fit matter.
Iowa regional screen
A small-grain comparison that needs a clear use case and planting window.
Iowa regional screen
An oilseed comparison where rotation, disease pressure, and buyer access need local review.
Iowa regional screen
A forage comparison where establishment, persistence, livestock use, and harvest plan change the decision.
Move from regional context to field evidence
Run the coordinate-level land audit before committing capital. Use the farm conversion cost calculator if the decision changes perennial crops or infrastructure.
Sources, scope, and update control
Evidence contract
The comparison guide explains how to read the existing regional pages. The pages use crop-profile reference fields and representative regional context. They do not convert currencies, set a fertilizer rate, measure a parcel, or produce a guaranteed yield or profit forecast. Display formatting is the only transformation described here.

Crop comparison questions
Which crop is better for my farm?
No crop wins for every farm. Compare climate, water, soil, rotation, equipment, labor, buyer access, and local economics against your field evidence.
What should I compare first?
Start with constraints that can rule out a plan: growing-season conditions, water reliability, soil depth and drainage, planting and harvest windows, and required equipment.
Can I choose a crop from gross revenue alone?
No. Gross revenue does not subtract seed, fertilizer, chemicals, labor, land, machinery, storage, marketing, financing, or risk. Use a local budget and your own assumptions.
Do AgriAuditor comparison pages use field measurements?
The public comparison routes are regional screening pages. They use crop-profile requirements and representative regional context, not a parcel soil test, field inspection, or guaranteed yield forecast.
Why does crop rotation affect the comparison?
The preceding and following crops change residue, nutrient credits, disease and pest pressure, timing, and equipment use. Check local rotation guidance before treating a pair as interchangeable.
How do I make a crop comparison specific to my field?
Open a regional comparison for context, then run the coordinate-level audit and replace reference economics with local costs, yield history, buyer terms, and water information.
Continue with the AgriAuditor methodology, review the NPK calculator guide, or use the farm grants guide when support programs affect the decision.
