Organic fertilizers are composed of organic materials. Compost, blood meal and manure are good examples of organic fertilizers. Organic fertilizers contain several organic molecules like carbohydrates, fat, DNA protein etc. The existence of such molecules is very important for the soil and the plants.
Benefits of organic fertilizers are all round; be it soil, plant, environment, eco-system or economy organic fertilizers have impacts on all.
On Soil
Organic fertilizers improver the physical structure of the soil and enrich soil with micro-organisms. Microbial activity is 10 to 20 times higher in worm castings than in the soil which in turn attracts deep-burrowing worms that are present in the soil. Nutrient holding capacity and water containing capacity of land increase many times if we apply organic fertilizers. Thus the land remains fertile for hundreds of years.
On Plant
Plant remains very healthy if they grown on organic fertilizers. Germination and growth of plants enhance by many folds. Plant root becomes sturdy, texture, flavor and color of the plant remain very much natural. As organic fertilizers increase the volume of micro-organisms in the soil plants grown on that soil are rich in hormones like auxins & gibberellic acid. End users who eat these organic foods are less prone to cancer, heart disease as well as skin disorders.
On Environment
Organic fertilizers don’t cause any environmental pollution because these are easily bio-degradable. Chemical fertilizers on the other hand are a cause of land and water pollution. Organic fertilizers minimize the ‘metabolic gap’ through recycling waste on-site. The production process of organic fertilizers is free from any emission of methane gas and nitric oxide.
If you see soil as a living organism (in fact it is) you can save the soil from ‘killing’ by using organic fertilizers. At the same time you can improve and sustain the soil. The real value of organic fertilizers is the slow release of nutrients as well as long term feeding of microbes. A good organic fertilizer contains large organic molecules that are not yet digested. In the process doing all-round benefits for mankind.
