Nitrogen is an important nutrient required for the proper growth and development of plants. Farmers usually plow and grow under alfalfa - a leguminous crop, to enhance the fertility of soil. This is because alfalfa adds more amount of Nitrogen in the soil than any other crop. Studies suggest that around 50 lbs. of nitrogen per acre can be added in soil each year by growing alfalfa in the crop fields. This has immense potential to overcome the problems that crops face due to lack of fertilizers.
A farmer grows and plows under of alfalfa to enrich the soil with <u>nitrogen.</u>
Explanation:
Nitrogen is a very helpful nutrient for the development of crops and plants. Farmers usually grow the crops under alfalfa- a leguminous crop, the only alfalfa contains much of the nitrogen. It produced much nitrogen is removed during the harvest. Legumes are plants, which are rich in proteins. Worldwide more than 16,000 species of legumes are known including trees, grass, herbs ,etc. Alfalfa puts more nitrogen back into the soil however, the crop still provides a great deal of added nitrogen to the soil based on a year growing alfalfa. Studies suggest that around 50 lbs. of nitrogen per acre can be added in the soil each year by growing alfalfa in the crop fields.
Chloroplasts are what give plants their green color. The second major difference between plant and animal cells is the cell wall. While both plant and animal cells have a cell membrane, on plants have a cell wall.
