Food Plot Seed, Lime & Fertilizer Mix

Standard agronomy math: rate per acre × your acreage, plus a sprayer tank-mix calculation.

How this works

Seed/lime/fertilizer needed = rate per acre × acres. Tank coverage = tank size ÷ sprayer output rate; product per tank = coverage × product rate per acre

This is standard agronomy math applied to a food plot instead of a farm field: multiply whatever per-acre rate your soil test (or seed bag) recommends by your actual plot size to get the total product needed, and separately work out how many acres one full sprayer tank will cover so you know how much herbicide or other product to mix into each tank.

Why soil testing pays for itself

Lime and fertilizer needs vary enormously by existing soil pH and nutrient levels — applying a generic rate without testing can badly under- or over-treat a plot. A soil test tells you the actual rates to plug into this calculator, turning a guess into a real plan.

Frequently asked questions

Do I really need a soil test before using this?

It's strongly recommended — lime and fertilizer needs vary enormously by existing soil pH and nutrient levels, and a soil test (often under $20 through a local extension office) gives you the actual rates to plug in here instead of guessing.

How do I figure out how much herbicide to mix per tank?

This calculator works out how many acres one full sprayer tank covers based on your tank size and output rate, then multiplies that by your product's per-acre rate to give the amount to mix into each tank.

What if my soil test gives lime in a different unit?

Convert it to pounds per acre before entering it here — most soil test reports already use that unit, but double-check since some report lime needs in tons per acre instead.
