Which of the following will be responsible for the poor yield of fertile soil in a high rainfall area?
Answer Details
In a high rainfall area, the poor yield of fertile soil may be due to leaching of soil nutrients. This occurs when there is excessive rainfall, which causes the nutrients in the soil to be washed away, leaving the soil nutrient-deficient. When this happens, the plants growing on the soil will not have the necessary nutrients for growth and development, which can lead to poor yield. The other options, such as low pH, lack of soil microbes, high alkalinity, and erosion, can also affect agricultural productivity, but they may not be specifically related to high rainfall areas.
