HI Friends,
I’m trying to create Organic Compost using cow dung and other naturally available stuff to create Organic Compost which has the same Nutrients as NPK & DAP. so that we can avoid 60 to 70% usage of the chemical fertilizer in our land.
Please let me know is there any method or substitute available.

Is there any way that we can create Organic Compost that can replace NPK & DAP chemical Fertilizer?

Hi there, one of the biggest challenges I found when using only organic compost to replace mineral fertilizers is the toxic build-up of micro nutrients. I agree with the notion to enrich the compost with chemical fertilizers. It has been shown that a good quality compost enhance the availability of minerals in chemical fertilizer, therefor having the potential to reduce the amount of chemical fertilizer. Also the use of controlled release fertilizers have ensured slower release of chemical fertilizer, increasing the nutrient use efficiencies of these fertilizers.

The simple answer is no. In most cases, the organic matter that we use to produce compost does not have a high enough nutrient content to achieve results anywhere near mineral fertilizers. Despite the potential to concentrate nutrients through composting due to the degradation and emission of carbon (thus concentrating the other constituents), nutrient loss during composting can be rather significant. Some studies have found nitrogen loss of above 90% of initial nitrogen during the process (through ammonia volatilization and (de)nitrification), while phosphorus losses of upwards of 30% have also been reported through leaching.

One possible method is to combine synthetic fertilizer with organic matter (compost) to produce organ mineral fertilizers. it may be a physical mixing or chemical combination

1. Application of binomial or phosphate rock: 1 kg of binomial or rock phosphate is applied over each layer of animal dung.
2. Use of animal bones: these can be broken into small pieces, boiled with wood ash leachate or lime water and drained, and the residue applied to the pits.
3. You may also use Azotobacter or Azospirillium culture to enrich nitrogen and PSB or phosphatase and phytase producing (PPF) organisms to enrich phosphorus.
