what is difference between nitrogen fixation and rotation of crops?
Answers
Answer:
Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds
Crop rotation can play a major role in minimizing the potential risk of nitrate leaching to surface and groundwater by enhancing soil N availability, reducing the amount of N fertilizer applied, and minimizing the potential risk of N leaching.
Crop rotation method involves growing of set of crops in a regular succession over a same piece of land in a specific period of time. Crop rotation maintains and improves soil fertility. This is achieved by raising leguminous crops. Leguminous crops provide shelter for soil bacteria like Rhizobium which is a nitrogen-fixing bacteria.
