Soil should be enriched with natural fertilizers such as organic and green manure and compost. Natural fertilizers are healthier for soil, plants, water, air and people than chemical fertilizers. Biofertilizers are applied to seed, root, soil, or by the foliar spray to enhance the microbial activity through their multiplication which then mobilizes the nutrients to target plants which remarkably improved the soil fertility and sooner increases the crop health and production. Biofertilizers enrich the soil with nutrients by fixing the atmospheric nitrogen, they solubilize the phosphorous thus, making it available to the plants. They stimulate the growth and development of plants by enhancing the secretion of growth-promoting substances. Such soil fertility management practices include the use of fertilizers, organic inputs, crop rotation with legumes and the use of improved germplasm, combined with the knowledge on how to adapt these practices to local conditions. Farmers can be very proactive to reduce denitrification on their farms, using various types of products to slow down N fertilizer release or using slow-release N fertilizers, such as environmentally smart nitrogen (ESN).
Can organic fertilizer provide all the essential nutrients for plant growth without any mineral additions?
Yes, Organic fertilizers are naturally available mineral sources that contain moderate amount of plant essential nutrients. Some organics can take longer to green up the soil. The results will come but maybe not as quickly as you want them. Delivers nutrients in a slow. The C, H &O and 13 essential elements (nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, iron, zinc, manganese, copper, boron, molybdenum, and chlorine) can be supplied from soil minerals and soil organic matter.
