  • The given statement is false.
  • Deforestation causes soil erosion, which has a negative impact on soil fertility and humus content. Soil erosion occurs when the protective cover of trees and vegetation is removed, leaving the soil exposed to the elements. This can lead to the loss of topsoil, which contains vital nutrients and organic matter that support plant growth. Additionally, deforested land is often cleared for agriculture, which can further deplete soil fertility over time through intensive cultivation practices and the use of chemical fertilizers and pesticides. While soil erosion may create new deposits of sediment that could potentially improve soil quality in some areas, this process can take hundreds or thousands of years and is not a reliable or sustainable method of improving soil fertility.
  • The correct statement is “Soil erosion from deforestation reduces soil fertility and humus levels."
