At a glance, you can see the color of the organic fertilizer. The organic fertilizer dried by physical methods still retains the color of the original feces, only the water is reduced. The organic fertilizer treated by composting technology turns brown or dark brown after being decomposed, and there are no other impurities in the finished product. The second touch can grasp a high-quality organic fertilizer by hand, the hand feel is consistent, the wet fat is soft and elastic; the dry fertilizer is very brittle and easily broken. Inferior organic fertilizers can be used to touch impurities, especially sand. Three blisters can take two cups of water, and put a little high-quality and inferior organic fertilizer, respectively, in a few minutes can be good or bad. Organic fertilizer adulteration is generally added sand or soil particles, high-quality organic fertilizer is evenly distributed in water, and the bottom of inferior organic fertilizer sinks into a lot of sand or soil, the difference is obvious.
