Process of mineralization that allow organic substrates under controlled successive microbial decomposition become stabilized organic matter in the presence of oxygen is Composting.

There is three main stages of composting:

1. Lag Phage (few days)

- The limit factor for this Lag Phage is a low population of microbes in the inoculum. The consumption of O2 is very low. There is no need of forced air supply at this Lag Phage of composting.

2. Exponent Phage (2-3 weeks)

- The limit factor for this Exponent Phage is O2. This phage is typical for high requirement of O2. The best equipment for this is Containerized Composting where the intensive air is supplied in controlled conditions.

3. Plateau Phage (1-2 months)

- The limit factor for this Plateau Phage is Carbonhydrate - the source of energy to microbe. The consumption of O2 is again very low. There is also no need of forced air supply at this Plateau Phage of composting.

Rock Phosphate

♦ The technology chosen is specific for treatment of apatite or rock phosphate in order to convert it to be soluble with organic compound. Specific microbes accelerate this process of conversion.

Rock Phosphate + Organic Matter = Organic Phosphate

♦ Besides phosphate, other minerals as calcium and magnesium is more soluble when treated with organic matters.

♦ The organic substances that make minerals become soluble are called chelating agents. Specific feature of chelating agents is ability to bind somehow with many elements, and make those nutrients soluble and thus available to plant.

♦ Decomposition is a long-term process. For that reason mineral organic fertilizers is a kind of slow released fertilizers. Slow release effect reduces leaching and evaporation that in some critic conditions cause the loss of 50% of fertilizers applied.

♦ During decomposing process many secondary substances released. In turn, those substances act like plant growth stimulants that improve plant growth and quality of development.
