People cultivate traditional farmyard manure are mainly livestock manure, fermented by indigenous and then applied to the field. Not only labour-intensive and time-consuming, and low crop yields, making fertilizer, low efficiency. While the development of modern agriculture relies on more modern fertilizer industry, fertilizer to agriculture has brought revolutionary change; also made modern agriculture developed rapidly, particularly in China, agricultural yield, fertilizers credited. But in the long run excessive application of fertilizers. Especially excessive dependence on chemical fertilizers, not only a lot of fossil energy, also caused soil compaction, soil fertility decline.
Nearly 30 years, world agricultural experts and the Government are actively promoted to reduce fertilizer application, application of organic fertilizers. Rise of Agriculture's "green revolution". Here we will introduce a new type of green manure one by one microorganism fertilizer.
Soil crop growth and development of plants, it is made of inorganic (mineral), organic matter and microorganisms, the three parts of the interdependent ecosystems. Soil mineral composition of the soil materials, namely plant growth substrate is a major source of plant inorganic nutrients and organic matter in the soil for fertilizer, fertilizer important material Foundation and the formation of soil aggregates and necessary ingredient to prevent soil compaction. Microorganisms in the soil, living organisms, is indispensable to active substances into soil fertility. Activity of soil microorganisms directly involved in the matter and energy transformation in soil, humus formation and decomposition. Nutrient release, nitrogen fixation, and other important processes of soil formation and development. Therefore, to increase the number of beneficial microbes in the soil will also enhance soil microbial activity, thereby increasing the fertility of the soil.
China of soil fertilizer research personnel after years tireless of efforts, has success to will nature in the has minority type can into soil difficult dissolved sex of p potassium mineral in the of p potassium elements for effective raised copies of microbial added also only very minority original nuclear class can will gaseous nitrogen curing into plant can absorption of ammonia State, and nitrogen pigment of solid nitrogen bacteria with made a new concept of fertilizer--microbial fertilizer (Microbialfertolizer).
Starting from the early 80 's, soil microbiologist found that many microbial secretions promote seed germination and root growth and plant growth hormones, have a variety of antibiotics inhibit the pathogen bacterium. Large amounts of beneficial bacteria by direct inoculation in the form of fertilizers to crop rhizosphere, not only for the crop with adequate fertility and crop growth, reducing disease, increase the absorption of moisture, increase crop drought resistance.
Therefore, the development of microbial fertilizers has many advantages, which can save energy, reduce production costs and provide sufficient energy; improving the quality of agricultural products and tastes. But its biggest advantage is that no contaminated food, does not pollute the environment.
