The correct answer is:
Grow a legume crop to support the development of root nodule
The best way that a farmer could increase the amount of nitrogen in his fields without adding synthetic fertilizer is to grow a legume crop to support the development of root nodules. This is because legumes have a symbiotic relationship with bacteria found in the soil.
Explanation:
Legumes use nitrogen fixing bacteria, specifically symbiotic rhizobia bacteria, within their root nodules to counter the limitation.The plant root cells convert sugar into organic acids which then supply to the rhizobia in exchange, hence a symbiotic relationship between rhizobia and the legumes.
Pea plants
These belong to legumes and legumes have a mutualistic relationship relationship with bacteria which allows them to add atmospheric nitrogen into the soil by a process called nitrogen fixation.<span />
