How to use natural mineral fertilizers?

    Natural mineral fertilizers mainly refer to mineral or rock resources that can be directly used for agriculture, without the need for complex processing, other than traditional NPK fertilizers. Nutrient content varies with specific minerals, such as glauconite containing potassium and various trace elements, nitrates containing nitrogen and potassium, and apatite containing potassium, phosphorus, and calcium.

However, it is generally free of nitrogen, phosphorus or low in content. The advantage is that it does not agglomerate after pulverization, can provide certain nutrients for crops, increase soil water retention and fertilizer retention, and improve crop disease resistance, and can be used as fertilizer, fertilizer additive or soil improver. Generally, various soils and crops can be applied, mainly as base fertilizer, and then ploughed into soil or mixed with organic fertilizer.
