Nitrogen Bio-fertilizer has been declared extremely useful for legume crops, including soybean, gram, groundnut, mash, pea, Jantar, groundnut, etc and the importance of bio-fertilizers grows rapidly over time because their use has prevented a rapid decline in the natural fertility of the soil. The use of bio-fertilizers can increase the yield of legumes by 15 to 100 percent. Bio-fertilizers contain such microbes, which not only maintain the natural fertility of the soil but also increase its number under favourable conditions. Some microbes in the soil can fix the atmospheric nitrogen and ensure better plant growth, these microbes make their home in the roots of legumes. Therefore, if there are sufficient numbers of these microbes in the field, then no chemical nitrogen fertilizer is required. After extensive research, agricultural scientists have developed a fertilizer containing these germs called Nitrogen Bio Fertilizer. Make sure farmers use bio-fertilizers to help them achieve better yields.
