How does soil affect the nutrient content of crops?
A.Plants develop nutrients on their own and acquire them from soil content. Common farming techniques are often geared toward increasing crop yield, thus researchers are questioning the quality of top soil (higher turnover), the amount of top soil loss, and suggesting that soil is overused. Farmers replace most of the nitrogen and potassium lost with each harvest, but researchers speculate that little attention is paid to the loss of other important minerals. This could have long-term effects in the overall nutrient content of plants.
