How to read a soil test for food plots

Why soil pH is everything

Soil pH controls how much of your fertilizer the plants can actually use. In acidic soil (low pH), nutrients get locked up — you can dump fertilizer on a plot and still get a weak stand. Most untouched dirt in deer country sits around pH 5.0–5.8, which is too acidic for the crops deer love most. Clover, alfalfa, and chicory want 6.5–7.0; brassicas and cereal grains are a little more forgiving but still prefer 6.0+.

Taking a good sample

• Use a clean bucket. Pull 8–12 small plugs from across the plot, 4–6 inches deep.
• Mix them together and let the composite sample dry.
• Send a cup to your state extension lab (usually $10–20) or use a mail-in kit. Ask for pH plus phosphorus (P) and potassium (K).
• Sample 3–6 months before planting so lime has time to work.

How much lime per acre

Lime raises pH, but slowly — it takes 6–12 months to fully react, so apply it as early as you can. These are rough rates for mineral soils to reach ~6.5; sandy soils need less, heavy clay needs more. Your soil test will give an exact recommendation.

Pelletized lime spreads easily but costs more per pound; bulk ag lime is cheapest if you can get a truck to the plot. One ton of ag lime ≈ 50 × 40 lb bags.

Fertilizer in one minute

Fertilizer bags show three numbers — N-P-K (nitrogen, phosphorus, potassium). Nitrogen drives leafy growth; phosphorus helps roots establish; potassium aids overall vigor. Key shortcut: legumes (clover, peas, beans, alfalfa) make their own nitrogen, so don't waste money on high-N blends for them — feed P and K instead. Brassicas and cereal grains, on the other hand, love nitrogen.
