Farmers, Soil, Fertilizer
Name: Sonia Z.
How do commercial farmers insure that their soil contains all the proper
minerals needed for healthy food? Do they fertilize with something other than the
traditional nitrogen, phosphorous and ---?
The soil is tested for pH, and major and minor nutrients. If the soil is deficient in some
mineral, then it is added with proper amounts of fertilizer for the crop in question. The
plants can be tested for nutrients also if showing symptoms of mineral deficiency.

Commercial farmers analyze their soil for nutrients, trace elements, water, water
retention, pH, and so on to ensure the proper balance. What specific substances
they use depends upon the crop and the soil.
