Answer 2

Hi friend!

Excessive use of fertilizers can tamper with the quality of the soil. This means that pesticides and fertilizers can cause the soil to be extremely acidic or basic. This prohibits the growth of some kinds of plants in the soil. This situation can be tackled in the following ways :

• Use organic manure and fertilizers in the place of chemical pesticides and fertilizers.
• Use methods such as field fallow and crop rotation in order to replenish the nutrients of the soil naturally.
• Do not water the plants immediately after using the chemicals. This will cause the chemicals to pollute the underwater resources.
• Try not to use chemical pesticides and fertilizers. If it is very, very essential, use them in a controlled manner.

Hope it helps you!!
