What is the difference between compound fertilizer and organic fertilizer?

The difference between compound fertilizer and organic fertilizer

1. Organic fertilizer
   It is mainly organic matter, low in nitrogen, phosphorus and potassium, and generally does not need to add chemical fertilizers. Organic fertilizer is the lowest-end product of crops, and it is the same as farmyard manure (a kind of natural fertilizer that uses various organic materials such as animal and plant residues or human and animal excrement in rural areas, and is used on-site or directly buried) and green manure. . The main function is to improve the soil, provide organic nutrients, improve quality, etc.
2. Compound fertilizer
   Chemical fertilizer for short, in a chemical fertilizer, fertilizer containing two or more of the main nutritional elements such as N, P, K, etc., is called compound fertilizer. Compound fertilizers containing two main nutrients are called binary compound fertilizers, those containing three main nutrients are called ternary compound fertilizers, and those containing more than three nutrients are called multi-element compound fertilizers. A large number of elements nitrogen, phosphorus and potassium are synthesized and belong to inorganic nutrients.

difference between the two

1. Organic fertilizer contains a lot of organic matter, which can be used to improve soil fertility, while compound fertilizer can only provide inorganic nutrients. Long-term application can cause adverse effects on the soil.
2. Organic fertilizer contains a variety of nutrients. The nutrients in organic fertilizers are completely balanced. The types of nutrients contained in chemical fertilizers are single. Long-term application can easily cause crop nutrient imbalance.
3. Organic fertilizers have low nutrient content and require a large amount of application, while compound fertilizers have high nutrient content and require less application.
4. The organic fertilizer has a long fertilizer effect period, and the fertilizer effect period is short and fierce, which is easy to cause nutrient loss and pollute the environment.
5. Long-term application of organic fertilizer can improve the quality of agricultural products. Improper application of compound fertilizer will reduce the quality of agricultural products.
6. After the organic fertilizer is completely decomposed, it can improve the drought resistance, disease resistance and insect resistance of crops. The application of compound fertilizers reduces the immunity of plants, and often requires a large amount of chemical pesticides to maintain the growth of crops. This will lead to an increase of harmful substances in agricultural products.

How effective are compound fertilizers and organic fertilizers

Organic fertilizers contain a lot of organic matter that is low in nitrogen, phosphorus, and potassium. It mainly comes from organic materials such as animal and plant residues or human and animal waste. Its main function is to improve soil, provide organic nutrients and improve quality.
Compound fertilizer is a kind of chemical fertilizer that contains nitrogen, phosphorus, potassium and other elements at the same time. Generally speaking, compound fertilizers containing two nutrient elements are called binary compound fertilizers, which are inorganic nutrients. The amount of application should not be too large, otherwise it will affect the quality of crops.
