The simple way to identify the quality of organic fertilizer
First, you should put the organic fertilizer sample in a cup of water, then crush the organic fertilizer soaked in the water by hand. After stirring, the raw materials of the organic fertilizer can be seen intuitively. And you leave it for a while. If the organic fertilizer and water are separated in a short time, it means that the organic fertilizer has a large proportion and contains more soil.
When you smell, you should smell carefully to see if there is the smell of ammonia, feces and sludge. The good organic fertilizer should have a smell of thorough fermentation.
