How do farmers replace nitrogen in the soil?

Answer 1

There are two ways plants put nitrogen into the soil one is decomposition where a plant dies then decomposes putting the nitrogen back into the soil that it once took out. The other is from the air, Legumes are plants that take nitrogen from the air with their leaves and release it into the soil with its roots.

Answer 2

Farmers replace nitrogen in the soil by using fertilizers that contain nitrogen such as ammonium nitrate or urea. They can also rotate crops with legumes like clover or beans that fix nitrogen from the air into the soil. Additionally, some farmers use organic matter like compost or manure to add nitrogen to the soil.

Answer 3

You can add natural components such as compost or horse manure and dig it into the soil.

You can plant 'nitrogen fixing' plants which encourage a bacteria known as Rhizobium to take nitrogen from the air and store it in the plant's roots. Peas and beans are common plants for this purpose.

You can also purchase fertilising chemicals with high Nitrogen content to treat your soil before and during planting .

Answer 4

* add fertilizer * add compost * grow leguems

Answer 5

one example: when animals die there bodies decompose. This decomposition returns nitrogen to the soil.

Answer 6

Nitrogen is put into the soil by the air having nitrogen naturally in it, animals waste, and the plants put nitrogen in the soil

Answer 7

Legumes such as clover, lupins,peas or beans.

Answer 8

Farmers apply fertilizers to the soil which replaces the nitrogen with its nutrients

Answer 9

Utilising plants which bind nitrogen into the soil, for example allowing clove to grow on the fields during a rest year will boost nitrogen levels
