There is also a general understanding of organic fertilizers. The raw materials are agricultural straw waste and livestock and poultry waste. Through large-scale straw crushing equipment, straw crushing and livestock and poultry manure are mixed with each other. After high temperature fermentation and maturity, they are processed through organic fertilizer production machine.The organic fertilizer production equipment process: organic material inoculation fermentation (pre-fermentation), main fermentation, crushing, compounding and mixing, drying, granulation, cooling, screening, measurement and packaging and other processes. There are problems in any link of organic fertilizer production, such as too many raw materials, too long straw crushing particle size, improper selection of granulator equipment, improper humidity control, etc. Therefore, fertilizers are rich in nutrients, but there are also good or bad factors.
There are several ways to identify the quality of fertilizers:
1) Take a water cup by the bubble method, soak the organic fertilizer sample in water, then pulverize the organic fertilizer soaked in water by hand, stir the raw materials of the organic fertilizer intuitively, leave it for a period of time, if the organic fertilizer and water are in a short time Layering means a large proportion of organic fertilizer and more soil.
(2) The hand twist method uses organic fertilizer as raw material, and rolls back and forth with the thumb and index finger. If there is a feeling of hurting the hand, there will be sand or other impurities.
3) Smell the smell of the fertilizer carefully to see if there is ammonia, feces or silt. A good organic fertilizer should be a mature smell.
4) Select some organic fertilizers to be applied to the soil, and some organic fertilizers not to be applied to the crops, and observe the performance of the plants. Good organic fertilizers have obvious effects on the growth, yield and quality of the plants.
5) Using the strain test method, take a water cup and put the organic fertilizer into it, sprinkle a little water (be careful not to soak the water, get wet on the line), and place it in a warm and suitable place. Good organic fertilizer will remove the head from the white Pythium Take it out from the middle, and the broken organic fertilizer particles will also see white mycelium inside.
