Organic fertilizers are those with plant or animal origins. Organic fertilizers have lower percentage of nutrients, in comparison with mineral or chemical ones, but usually provide acceptable amounts of nutritional requirements for trees. In addition to main elements (N, P, and K), organic fertilizers consist of micro elements (Ferrous, Zinc, Copper…). Nowadays, mass residue of traditional and industrial poultry farms is a serious problem for their owners and they are very willing to sell the residue to organic fertilizer producing plants. Accumulation of these materials gradually leads to severe pollution of air, soil and water.
1) They can be replaced by mineral fertilizers to a high extent and as mineral fertilizers have high prices, utilizing organic fertilizers reduces the costs.
2) In these fertilizers it is possible to change the percentage of macro and micro elements arbitrarily. In other words, based on nutritional requirements of various areas, different formulas (containing desired percentages of macro and micro elements) can be produced.
3) In accordance with soil and water conditions, it is possible to add useful biological materials, like bacteria (Thiobacillus), fungi and useful microorganisms, to these types of fertilizers to improve soil characteristics and optimum absorption.
4) In contrast to most of the chemical fertilizers, the organic ones have more sustainability in soil and sometimes can be effective up to 2 to 3 years.
