The Complete Soil Test provides complete analysis for plant nutrients and soil conditions. It measures soil pH (acidity/alkalinity), percent organic matter, phosphorus, potassium, magnesium, calcium and the secondary and micronutrients; sulfur, iron, zinc, manganese, copper and boron. It also evaluates soil texture and classifies the soil by percent sand, silt and clay into one of the 12 soil types (i.e. silty loam, clay loam, sandy clay etc.) The textural analysis will provide information on how to amend the soil to gain better drainage, aeration and root development PLUS some tips on how to fertilize the soil. We recommend this test for new landscapes, buying topsoil and when diagnosing a relentless plant problem when all else has failed.
