Different crops use different nutrients in the soil. if the same crop is planted in a field year after year, soon the nutrients the crop needs will be used up. what measure do many farmers take in order to control this issue?

By practicing crop rotation

Explanation:

Crop rotation is an agricultural practice in which farmers carry out recurrent succession of crops on the same piece of land in different growing seasons.

Successive crops in a crop rotation regime have different characteristics based on the part of the soil they utilized for their growth.

For example, a crop that utilize nutrients from the surface of soil (surface feeder) may be planted in a season while another plant that utilizes nutrients from the deeper part of the soil (deep feeder) may be planted in its place the following season.

This practice will give ample time for the surface soil nutrient to be replenished before another surface feeding crop is planted.
