Which of the following statements is not correct about the ecological effects of agricultural activities?
Answer Details
The statement that is not correct about the ecological effects of agricultural activities is that monocropping is one of the cultural methods of controlling pests. Monocropping, which is the practice of growing only one crop on a large area of land, can actually increase pest problems because it creates a favorable environment for pests to multiply and spread. This can lead to increased use of pesticides, which can have harmful effects on the environment and human health. The other statements are correct about the ecological effects of agricultural activities. The use of herbicides and pesticides can cause pollution, bush-burning can encourage desertification, excessive use of fertilizers can have harmful effects, and tillage of tropical soils with ploughs and harrows can encourage erosion.
