How about chemical fertilizer Mei Jia?

It should be mineral fertilizer. A product of American Meisheng Company is mined underground and is rich in mineral elements such as potassium, magnesium and phosphorus. This is a good fertilizer. Domestic stones containing various minerals are calcined, so that elements that crops cannot absorb are easily absorbed by crops. There are several factories in Shanxi and Shaanxi of China. In view of the fact that farmyard manure is not used in the field at present, there is a lack of nutrients and the use effect is good.
