Quickly identify the "three methods" of organic fertilizer

Organic fertilizers are processed from organic waste materials such as livestock and poultry excrement. The quality of organic fertilizers directly affects the use of fertilizers. It is not difficult to distinguish organic fertilizers according to scientific methods. It is usually judged by "a look, two touches, and three blisters."

A look: Look at the appearance color of organic fertilizers. The physical method of dry organic fertilizer still keeps the color of the original manure, but the water content is reduced. The organic manure treated by the composting technology becomes brown or dark brown when it is decomposed, and there is no other impurity in the finished product. .

Second touch: Hand-grip a high-quality organic fertilizer, its feel is the same, soft and flexible when wet, when dry is very brittle, easily broken, poor organic fertilizer can touch impurities, especially sand.

Three blisters: Take two cups of clear water and put in some high-quality and inferior organic fertilizer. Organic fertilizers are adulterated by adding sand or soil to increase weight. High-quality organic fertilizers are evenly distributed in water, and the bottoms of inferior organic fertilizers sink into a lot of sand or soil.

In addition, it is only possible to select good organic fertilizers from the raw materials when selecting organic fertilizers. This is the reason why “good raw materials can produce good fertilizers”.
