The inclusion of clover as a forage crop and turnips as a root crop removed the need to have an area devoted to fallow.

What are the benefits of four-course rotation?

Crop rotation benefits include : – increased crop yield, and increased soil nutrients. – Weeds are less stressed as a result of this. – Reduces pollution, diversifies the economy, and lowers the cost of production by improving soil structure. – It allowed for the use of all of the land each year.

Why does farmer rotate crops in the field Class 8?

They adopt crop rotation to maintain the balance of nutrients in the soil. Different crops require different nutrients. Some crops may require more of some particular nutrients and less of others. Therefore, farmers plant different crops each season to prevent the depletion of nutrients in the soil.

Definition of three-field system : a system of land cultivation under which the common land is divided into three parts of which one or two in rotation lie fallow in each year and the rest are cultivated.

Why do farmers rotate crops?

The difference between the profit(loss) that you get and the profit you could have had is the disadvantage of crop rotation. That is the short run answer.

What is the main purpose of crop rotation?

Crop rotation helps with various components of crop and soil health. Some of the major advantages are controlling diseases & nematodes and balancing fertility demands but improved soil tilth & structure is another one that farmers put a lot of thought into.
