Classification, function and application notice of organic fertilizer
The organic fertilizer is not easy to dissolve in water, the decomposition is slow and controlled-release fertilizer. The composition of organic matter, such as cellulose, hemicellulose, fat, protein, amino acids and humic acid; and nitrogen phosphorus and potassium, calcium, magnesium, sulfur and trace elements and other mineral nutrients, rich nutrition, is a kind of complete fertilizer.
01
Types of organic fertilizer
Considering the fertilizer sources, properties, methods and Prospect of composting, the organic fertilizer, manure, manure, fertilizer, straw and organic fertilizer product categories. In addition, there are peat, peat, pond mud and garbage River (River) is an important source of organic fertilizer.
02
The role of organic fertilizer
03
Commonly used organic fertilizer ingredients
From the above table we can see that the total content of chicken manure fertilizer in the highest total fertilizer content of soybean meal in the highest class of cake.
04
Common organic fertilizer and application notice
1, human excrement
Is a good organic fertilizer, fertilizer efficiency is faster than the general organic fertilizer, is organic fertilizer in the quick fertilizer. Fresh human excrement is neutral, nitrogen, and phosphorus, potassium, should be used with P and K.
Matters needing attention：
Long term use alone can destroy soil structure and cause soil compaction. Therefore, it must be fermented, mature and applied, usually stored in 10~15 days until maturity.
The storage should be selected in a septic tank can not Water Leakage shade areas, and should cover (anti ammonia volatilization); 2 ~3% SSP, can play a role but also nitrogen fertilizer, phosphorus fertilizer can supplement and improve the quality of.
2, manure
From animal manure, food residue and fiber gasket material by fermentation and. Rich in organic matter, generally reach 15%, high up to 30%.
Matters needing attention：
Fresh manure containing hard decomposition of cellulose and lignin, carbon nitrogen and nitrogen was relatively large, most of the organic state, such as the direct use of fresh manure, soil moisture and nutrient uptake by microbial decomposition process and fertilizer for crops.
3, cake
Also called Youbing (litter), oil seed extraction, the residual oil after become dross, cake fertilizer, nutrient rich. The cake is the best fruit quality organic fertilizer, mainly used as fertilizer and manure, compost, and mixed fertilizer, but also can be used as fertilizer.
Matters needing attention：
As topdressing after maturity can be used to direct application, should be fully applied into the cake after crushing, ditching, and slightly away from the root, to avoid fermentation fever burns root.
4, composting reactor
The use of straw, weeds, green manure, peat, waste and livestock manure and other raw materials mixing, composting or retting and fertilizer in a certain way.
Matters needing attention：
The nutrient content and organic matter of thermophilic compost were higher than those of conventional compost.
5. Green manure
Is an important producer of fertilizer, green manure crops to orchard legume crops, the rhizobia have the ability of nitrogen fixation. With the wide application of interplanting green manure fertilizer, labor saving, convenient self fertilizer, soil and increase soil fertility effect.
6 straw fertilizer
Straw except contain cellulose, hemicellulose, lignin, protein and other organic matter, also contains a variety of elements to crops; can promote soil microbial activity and soil fertility improvement, reduce the amount of chemical fertilizer.
7, commodity organic fertilizer
The fertilizer made from fermented livestock manure, animal and plant residue and so on, which contains abundant organic by-products as the main raw material, is fermented and matured. There are many kinds of organic fertilizer, and their performances are different.
