Crop rotation is a method of soil conservation because . a. the land produces more than one type of crop b. it requires plowing and tilling that reduces soil compaction c. it does not use the same parcel of land in sequential seasons d. it avoids the depletion of soil nutrients

d. It avoids the depletion of soil nutrients.

Explanation:

Crop rotation is the process of planting different crops in the same area of land in rotation. This allows the breathing of the soil as well as the retention of nutrients in the soil.

Crop rotation is one form of conserving soil as it helps in saving the nutrients of the soil from getting depleted. As different crops require different nutrients, the change in crop plantation between different types of crops help in maintaining the fertility of the land. This way, when crops are planted in rotation, there is also the rotation of the different nutrients required for the different crops planted, thus allowing the cycle of nutrient change to take place.

Thus, the correct answer is option d.

that is wrong, its not thymus.
