    Ploughing the soil makes it aerated and easy to manure. Ploughing soil is then levelled for uniform and easy irrigation. The top soil is very much important for plant growth. It contains nutrients. If it is lost by wind or water erosion, it would adversely affect the crop production. Thus, enlightened management of land is essential for sustaining good crop yields year after year.
