The difference between organic fertilizer and chemical fertilizer and scientific fertilization and fish farming

Types and characteristics of organic fertilizer products

Compost products can be divided into common organic fertilizer, bio-organic fertilizer and organic-inorganic compound fertilizer according to different processing technologies. Ordinary organic fertilizer is a kind of commercial organic fertilizer, which is made of various organic wastes and fully decomposed by high temperature fermentation. It is powdered or granular. Commercial organic fertilizer has complete nutrient elements, which can improve soil, improve soil physical and chemical properties, and enhance soil water, fertilizer and fertilizer retention capacity.

The difference between organic fertilizer (bio-organic fertilizer crops will be compared below) and compound fertilizer

organic fertilizer

Total nutrient elements

improve soil

Improve product quality

Improve the microbial community in the rhizosphere of crops and improve the ability of plants to resist pests and diseases.

It can promote the utilization of chemical fertilizer and improve the utilization rate of chemical fertilizer.

Compound fertilizer (a chemical fertilizer)

Two or more nutrient elements

Frequent use will cause soil hardening.

The microbial population of crops is single, which is prone to pests and diseases.

It is easy to cause nutrient fixation and loss.

Summary: Organic-inorganic compound fertilizer refers to a compound fertilizer with both organic and inorganic nutrition, which is produced by adding an appropriate proportion of inorganic nutrition on the basis of organic fertilizer and further processing.
