The Soil Testing in Agricultural Science Directory

The soil test is an excellent measure of soil fertility. It is a very inexpensive way of maintaining good plant health and maximum crop productivity. The standard soil test provides the status of phosphorous P, potassium K, calcium Ca, magnesium Mg, pH, cation exchange capacity, lime requirement index, and base saturation. Additional tests are also available for iron Fe, zinc Zn, manganese Mn, soluble salts, and nitrates.
