For: Hunters and landowners planting food plots
Free food plot calculators: seed, lime and fertilizer from your plot size and soil test.
Each result has a plain-words line saying how it was reached, and each page lists the formula.
Rules and values come from regulators, university extension services and manufacturers. They are linked on every page and collected on the Sources page.
What you type stays on your device, and there is nothing to sign up for.
We re-open every source every three months, and sooner when a rule changes.
