Carbon containing materials primarily derived from plants and/or animals applied to the soil to supply plant nutrients as their primary function. Processed from biological substances, animal and plant waste, and plant residues, it eliminates toxic and harmful substances and is rich in many beneficial substances, including various organic substances, peptides, and rich nutrient elements such as nitrogen, phosphorus, and potassium. Not only can it provide comprehensive nutrients for crops, but it also has long fertilizer efficiency, can increase and update soil organic matter, promote microbial reproduction, improve soil physical and chemical properties and biological activity, and is the primary nutrient for green food production.

In a broad sense, organic fertilizer, commonly known as farm manure, includes various animal and plant residues or metabolites, such as human and animal manure, straw, animal residues, slaughterhouse waste, etc.

The difference between organic fertilizer and biological bacterial fertilizer

Biological microbial fertilizer (microbial fertilizer) is a product that uses the life activities of microorganisms to produce specific fertilizer effects on crops, and is a type of fertilizer used in agricultural production. It has a history of nearly 50 years in China, and the evolution of its name from rhizobia agent to bacterial fertilizer to microbial fertilizer has elucidated the gradual development of microbial fertilizers in China. For a long time, there have been some misunderstandings and prejudices about microbial fertilizers in society.

One viewpoint believes that it has high fertilizer efficiency, treating it as fertilizer and even claiming to completely replace chemical fertilizers; Another viewpoint is that its foundation is not fertilizer.
