Although China's agriculture is developing faster and faster, crops and fertilizers are inseparable. Among them, organic fertilizer is indispensable in agricultural development. People who do not know the market are easily deceived. Therefore, we will tell you in detail how to distinguish the quality of organic fertilizer.

As we all know, organic fertilizer also has a common understanding that its 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 together. After high-temperature fermentation and maturation, a fertilizer is processed through organic fertilizer production line equipment. Fertilizers are rich in nutrients, but there are also good or bad factors, such as too many raw materials, too long particle size of straw crushing, etc., but there are also the following methods to identify the quality of fertilizers:

1) Take a water cup with bubble method, soak the organic fertilizer sample in water, then crush the organic fertilizer soaked in water by hand, intuitively stir the raw materials of organic fertilizer, and place for a period of time. If the organic fertilizer and water are layered in a short time, it means that the proportion of organic fertilizer is large and the soil is more.

(2) The hand twisting method uses organic fertilizer as raw material, and rolls back and forth with the thumb and forefinger. If there is a feeling of hurting the hand, there will be sand or other impurities.

3) Smell the smell of fertilizer carefully to see if there is ammonia, feces and sludge. A good organic fertilizer should have a mature taste.

4) After the selection of organic fertilizer, some organic fertilizer is not applied to crops, and the plant performance is observed. Good organic fertilizer has a significant impact on plant growth, yield and quality.

5) Check whether the packaging meets the specifications and whether it is approved for production (generally, the approved production has no own factory and no source of raw materials).

6) The manufacturer of the organic fertilizer turnner pointed out that using the strain test method, take a water cup to put the organic fertilizer into it, sprinkle a little water (be careful not to soak in water, wet the line), and place it in a warm and suitable place. Good organic fertilizer will take its head out of the white rot mold, and the broken organic fertilizer particles will also see white mycelium inside.
