Soil test results from your state extension lab cost $10-20 and tell you exactly what your plot needs. Skipping the test and over-applying fertilizer wastes money and pushes weeds; under-applying produces weak stands that get overgrazed and don't recover.
Lime is often the highest-leverage amendment — most untreated woods soils are pH 5.0-5.5, well below the 6.0-6.8 range food plot species prefer. See farm-side soil test guidance for reading results.
