Organic fertilizers

Organic fertilizers are derived from animal, human and vegetable matters. They include the wastes from animal meat processing, peat, manure, guano etc.

 
Peat is a natural accumulation of partially decayed vegetation which is called peatlands or mires. Peatlands are very slow to develop, it takes up to thousand years to build a 1.5 m peatland. Peat is also used a vital source of fuel. The bad side of peat usage is peat fires which lead to huge health disasters.

 
In agriculture peat is mixed with the soil to improve its quality. Dry peat helps to retain moisture in soil while wet peat helps to prevent an excess of water. Peat itself is not fertile, it is an instrument to improve the soil fertility.

 
Peat is not only beneficial for humans, but also hazardous as it releases thousands of tons of methane gas into the atmosphere.

 
Other organic fertilizers include human and animal wastes which contain humic acid and amino acids.

 
These organic products can be also hazardous for humans and environment unless their use is strictly supervised against water and soil pollution.

 
Other sources of organic fertilizers are ash, animal blood and bone, compost, wood chips etc.

 
Despite organic fertilizers do not require industrial premises for production, they request a lot of resources to collect, store and distribute.
