How to Make Organic Fertilizer at Home?

Organic animal manure composting is necessary and inevitable when households make your own fertilizer at home. Composting waste is also an efficient and economic way in livestock waste management. There are 2 kinds of composting methods available in homemade organic fertilizer process. 
1. General Composting
Temperature of general compost is less than 50℃, having a longer composting time, usually 3-5 months. There are 3 piling types: flat type, semi-pit type, and pit type
Flat Type: suitable for areas with high temperature, much rainfall, high humidity, and high groudwater level. Choosing a dry, open land close to water source & convenient to transport. The width of stack is 2m, height being 1.5-2m, length managing by raw materials quantity. Ramming down the soil before stacking, and covering each layer of materials with a layer of grasses or turfs to absorb oozed juice. The thickness of each layer is 15-24cm. Adding right amount of water, lime, sludge, night soil etc. between each layer to decrease evaporation and ammonia volatilization. Driving self-propelled compost turner(one of the most important composting machine) to turn the stack after one month’s stacking, and so forth, until eventually materials are decomposed. Adding suitable amount of water in accordance with the wetness or dryness of soil. The composting rate varies by season, usually 2 months in summer, 3-4 months in winter. 
Semi-pit Type: usually used in early spring and winter. Choosing a sunny and lee site to dig a pit with 2-3 feet depth, 5-6 feet width, and 8-12 feet length. On the bottom and wall of the pit, there should be air passages built in the form of a cross. The top of the compost should be sealed properly with earth after adding 1000 catties dry straws. Temperature will rise after one week’s composting. Usinggroove type compost turner to turn the fermentation heap evenly after temperature decrease for 5-7 days, then keep stacking until eventually raw materials are decomposed. 
Pit Type: 2m depth. It is also called: Underground Type. Stack method is similar to semi-pit type. During the decomposing process, double helix compost turner is applied to turn the material for a better contact with the air. 
2. Thermophilic Composting
Thermophilic composting is a principal method to innocuously treat organic materials, especially human wastes. Harmful substances, such as germ, eggs, grass seeds etc. in straws and excretion, will be destroyed after high temperature treatment. There are 2 kinds of composting methods, flat type and semi-pit type. The technologies are same with general composting. However, to speed up the decomposition of straws, thermophilic composting should inoculate high temperature cellulose decomposition bacteria, and establish aeration equipment. The cold-proof measures should be done in cold areas. High temperature compost passes through several stages: Fever-High Temperature-Temperature Dropping-Decomposing. In high temperature stage, harmful substances will be destroyed.
