Which of the following farm practices can cause loss of soil fertility?

Intensive cropping can cause loss of soil fertility. This is because when crops are grown continuously without rotation, the soil is depleted of essential nutrients that the crops need to grow. As a result, the soil becomes less fertile over time, which can lead to reduced crop yields. On the other hand, mulching, compost application, use of fertilizers, and terracing are farm practices that help to maintain or improve soil fertility. Mulching and compost application add organic matter to the soil, which helps to retain moisture and nutrients. Use of fertilizers adds essential nutrients to the soil, while terracing helps to prevent soil erosion and runoff, which can lead to loss of soil fertility.
