Crop Residue Value Calculator

Estimate the nutrients contained in corn stalks, soybean residue or wheat straw and their approximate fertilizer replacement value. Use yield, acres and your current fertilizer prices to put residue nutrient cycling into economic terms.

Enter your numbers to see results.

Important: Residue nutrient values are estimates, not guaranteed first-year fertilizer credits. Fertilizer value uses the products and prices you select and credits nutrients supplied by multi-nutrient products. Residue quantity and nutrient concentration vary by crop, yield, weather and field conditions.

Managing corn or soybean residue instead of removing it?

Meltdown by BW Fusion is designed to speed residue breakdown and nutrient cycling in corn stalks and soybean residue while helping create a cleaner seedbed for the next crop.

Crop Residue Contains Valuable Nutrients

Corn stalks, soybean stubble and wheat straw contain nitrogen, phosphorus, potassium and sulfur. The amount of residue and nutrient content varies by crop, yield, weather and field conditions.

Residue Value Is Not Immediate Cash Value

Nutrients in residue are not all released at once and are not identical to applying commercial fertilizer. Weather, residue size, soil biology, temperature, moisture and tillage influence decomposition and nutrient release.

Use Residue Value to Think About Nutrient Cycling

Estimating residue nutrient value helps put residue management into economic context. It can also help compare residue removal, baling and decomposition strategies.

Frequently Asked Questions

Are nutrients in crop residue immediately available?

No. Nutrients are released over time as residue decomposes, and release rates differ by nutrient and field conditions.

Does higher yield create more crop residue?

Generally, higher grain yield is associated with more crop biomass, although residue amount varies with genetics and growing conditions.

Can residue replace all fertilizer needs?

No. Residue nutrient cycling is one part of the soil fertility system and should be considered with soil tests, crop needs and nutrient-management goals.
