Microbial organic fertilizer production line

Microbial organic fertilizer is a type of fertilizer that combines microbial and organic fertilizer effects, consisting of specific functional microorganisms and organic materials mainly derived from animal and plant residues (such as animal manure, crop straw, etc.) that have undergone harmless treatment and maturation.

Appearance: Powder should be loose and free from unpleasant odors; Granular should have no obvious mechanical impurities, uniform size, and no putrid odor.

Microbial organic fertilizer has complete nutritional elements, which can provide comprehensive nutrients for crops; and has high organic matter content, which can improve soil, improve soil physical and chemical properties, enhance soil water retention, fertilizer retention, and supply capacity, and alleviate soil compaction caused by long-term use of chemical fertilizers.
