Organic fertilizers
such as increasing the fertility of the microorganism that soil and provide the plants the main nutrients are known as organic fertilizer such Ajotobactor, Streptomaises, rhizobium, cyanobacteria, phosphate Salbulaijing bacteria, Ajospirilm etc. Dr. Manoj Kumar Pandey, Crop Protection Specialist of Krishi Vigyan Kendra, Bejwan, Bhadohi, Uttar Pradesh informed that Rhizobium biofertilizer is used in pulse crops while Azotobacter, Streptomyces are used in wheat. Further, the main crop grown in Kharif is the use of blue green algae, Azospirillum in paddy. The
use of blue green algae in paddy saves 25-30 kg of nitrogen per hectare.

To
maintain the fertility of green manure soil, increase in production, it is necessary that the health of the soil should be balanced. Soil fertility can be increased with green manure. Dhaincha for green manure, the time for sowing of Sunai has started. Green manure is the simplest and least cost method through which the land can be made fertile. Its use increases the number of native earthworms in the land and all the main and micro nutrients required for crops, organic carbon, humic acid, enzymes, vitamins, hormones, various micro-organisms like friendly bacteria and friendly fungus, organic acids etc. In particular, there is an increase in nitrogen storage in the land and our land becomes fertile. The water holding capacity of the land increases as well as air circulation increases.

For many years we have been continuously cultivating our fields by using chemical fertilizers and other toxic chemicals. The use of different types of cow dung and other organic fertilizers is almost non-existent or has been stopped. As a result of which organic carbon, friendly micro-organisms, friendly fungi, and essential nutrients are becoming lacking in our land. The physical and chemical composition of the land has deteriorated, the soil's turbidity is turning into hardness. The salinity and alkalinity of the soil is increasing. Our land is dying. Due to which the production of crops has stagnated or is decreasing. If this situation continues, then one day our agriculture may become barren.
If we want to save our fields from becoming barren and give a good future in agriculture field for our next generation, then we have to use different types of manures made from regular cow dung and regular green manure in our fields.
For this, we should sow green manure after the harvest of wheat crop in the months of April to May in water-supplied fields and in rainfed areas when monsoon arrives. Fast growing pulse crops like Dhencha, Sunai, Cowpea, Guar, Moong, Urad etc. can be sown for green manure. Generally, Dhencha and Sunai are most suitable for green manure and biomass is also obtained from them. Dhencha is a crop that can tolerate water shortage or drought after germination and can also tolerate water logging in the rainy season when more water falls. For this, farmers can sow by plowing the field if there is a means of irrigation. For sowing per hectare, 60 kg dhaincha and 80 kg hemp seed is required. For dhaincha, it would be better to sow the seeds of Hisar dhaincha 1 and Narendra dhaincha 1 species. Sunai should be applied where there is little rain.
Green manure is turned into the soil with iron plow, disc harrow or rotavator before flowering in about 45 to 55 days after sowing, at this time there should be enough moisture in the field so that green manure gets decomposed soon, Green manure crop gets decomposed soon by using Trichoderma, Ghan Jeevamrut, Jeevamrut, Waste Decomposer or mustard oil in the field while turning the manure.

There is a special quality in the pulse crop that it stores the existing atmospheric free nitrogen in the soil through Rhizobium bacteria in its roots, so that the next crop sown in the field gets sufficient amount of nitrogen and all other essential nutrients are available. becomes. Due to which on one hand the health of our land improves and on the other hand the use of chemical fertilizers can also be reduced. By sowing green manure in your farm before planting paddy, you can reduce the cost of chemical fertilizers by transplanting paddy by turning green manure in the field when monsoon arrives. The use of green manure not only increases the availability of nutrients in the land, but also improves the soil structure, and the number of microorganisms and beneficial organisms found in the soil increases.

Benefits of
green manure – Green manure increases the amount of organic carbon, organic matter and many nutrients in the soil. And at the same time the availability of nutrients present in the soil increases for the plants.
Nutrient degradation is minimal.
The water holding, storage and air circulation capacity of the land increases.
The activity of beneficial microorganisms also increases. The number of earthworms, friends of farmers, increases. With the increase in crop production, the quality also improves.
Weeds grow less.
- Increases the amount of nitrogen. The use of green manure improves the soil.
