Descirbe any two practices of Sustainable Agriculture.

Explanation

1 Crop rotation:- The crops are picked in a pattern so that the crops planted this season replenish the nutrients and salts from the soil that were absorbed by the previous crop cycle. e.g., row crops are planted after grains in order to balance the used nutrients. This maintains the soil fertility.
2. IPM :- It is a pest control technique realising that all pests are not harmful so allowing them to co-exist with the crop. This involves targeted spraying works, to remove the specific harfmul pests. So it protects the wildlife from getting affected, e.g., Baculoviruses of genus Nucleopolyhedro viruses are used in IPM.
