1. Organic fertilizer:

Fertilizer containing mainly organic matter is called organic fertilizer. Such as compost, manure, green manure, peat (peat), humus, human feces, poultry manure, bean cake, etc. Organic fertilizer contains a variety of elements and is also called complete fertilizer. Because organic matter must be decomposed by soil microorganisms before it can be absorbed and utilized by seedlings, it is also called slow-release fertilizer.

2. Inorganic fertilizer:

Inorganic fertilizer is also called chemical fertilizer or mineral fertilizer. Most of them are industrial products, which do not contain organic matter and have high nutrient content. The main ingredients are soluble in water and can easily be converted into ingredients that can be absorbed by the seedlings. The fertilizer effect is fast. Most inorganic fertilizers are quick-acting fertilizers, such as nitrogen, phosphorus, potassium fertilizers, granular fertilizers, compound fertilizers, trace element fertilizers, etc.

3. Microbial fertilizer:

Microbial fertilizer is a general term for various microbial fertilizers made by cultivating microorganisms in the soil that are beneficial to the growth of seedlings. It includes nitrogen-fixing bacteria, rhizobia, phosphate bacteria, potassium bacteria and other bacterial fertilizers and mycorrhizal fungus fertilizers
