As mainly product, high content of bio-organic fertilizer ( spore powder ) is compound bacterial powder of Bacillus Azotofixans, Bacillus megatherium and Bacillus mucilaginosus. It was bacteria with spore, which is able to bear -40℃~80℃, and resolve the problem that dry temperature cause low content of effective bacteria; Because of thick and concentrated spore wall, low humidity and unpenetrable, it can prevent chemical infiltrate, and applying with chemical fertilizer dispose of nutrient demand and fertilization balance; Its valid period extend 18 months, high content of bacteria reach up to 2.5 billion/g. In addition, combined microbial technique and prescription fertilization through soil mensuration to product kinds of distinct prescription of high nutrient of “ Big Three Element” bio-organic fertilizer, which will be used everywhere genuinely for its good commodity and suitability.

Major technical criterion:
•  5 billion/g ≥ Content of effective bacteria ≥ 1 billion/g
•  Valid period: 24 month
•  Annual decrease rate of effective bacteria: about 10%
Application: different crops according to different formula for producing microbial fertilizers
Directions:
1. According to the requested content of effective bacteria in fertilizers (A), the formula for adding the bacterial stain agent powder (N) is as following:
N=A （ 100 million/g ）÷ C （ 100 million/g ） *1000 （ kg ）
C stands for the content of effective bacteria of the strain agent powder.
Example:
The content of effective bacteria of the strain agent powder (C) is 2 billion/g, and the request is to produce fertilizers with 25 million/g for content of effective bacteria, then the strain agent powder to add in fertilizers per ton:
N1=(0.25/20)*1000 （ kg ） =12.5kg
2. Mix the strain agent powder evenly with other organic fertilizers and chemical fertilizers evenly to make granular-shaped or powder-shaped complex microbial fertilizers and packed.
