Product Discription
The organic fertilizer made from compost fermentation of organic materials contains abundant organic matters, humic acid, nutrient in organic state, medium and trace elements, and a plentiful beneficial microorganism. This product has obvious effect in improving crop quality and increasing yield and increment, in terms of improving plant root system of plant, soil activity, physical and chemical property, remitting soil hardening, promoting growth and development of crops, accelerating precocity, enabling the crops to have developed root, thick stem and thick leaf, enhancing the crops’ ability on drought resisting, anti-water-logging, cold resistance, logging-resistance and disease-resistance.
There are basically three stages for aerobiotic compost fermentation process: initial period, high-temperature period and cooling and curing period. Main microorganism species in the process is bacteria, fungus and actinomycetes.
1) Initial period
The non-heat resisting microorganism decomposes the easily degradable carbohydrate and fat contained in organic matters, and at the same time releases heat to rise temperature of materials which can be up to 40℃.
2) High-temperature period
The heat-resisting microorganism breeds rapidly. Under aerobic condition, most degradable protein and fiber are continuously oxidized and degraded, and meanwhile release a lot of heat which makes material’s temperature up to 60-70℃, by which a majority of the pathogenic bacteria and parasites can be killed.
3) Cooling and curing period
High-temperature period consequentially causes death and reduced activity of microorganism, and it then enters low-temperature period. At this period, thermophilic microorganism starts to dominate, and decompose the organic materials in remnant that is hard to decompose. However, the microbial activity declines generally, the heat from compost reduces, temperature starts to drop, organic matters become stable, and the oxygen demand dramatically reduces. Then the compost fermentation passes into thoroughly decomposed period or after-ripening period, forming into humus.
