Fertilizer: What are the differences between organic fertilizer, compound fertilizer, and complex fertilizer?

9-16 2023
  1. Introduction to organic fertilizer, compound fertilizer and complex fertilizer

Organic fertilizer made by fermenting and processing various animal manure, plant residues, or metabolites. Compound fertilizer refers to a fertilizer made by chemical or blending methods with at least two designated amounts of nitrogen, phosphorus, and potassium nutrients; Complex fertilizer refers to the chemical method used to produce at least two of the three nutrients, nitrogen, phosphorus, and potassium, with designated amounts.

  1. Advantages

Organic fertilizer:Improving soil quality; Protecting the environment; Increase crop output value and quality

Compound fertilizer: with high effective ingredients and a variety of nutrients; Less side components and minimal adverse effects on soil; Low production cost; Good physical properties

Complex fertilizer: High fertilizer efficiency and utilization rate; Good physical properties and convenient application; Promote soil nutrient balance; Accelerating the promotion and application of formula fertilization technology.


  1. Differences

1.Different fertilizer production process

Organic fertilizer:It requires the processing,composting, fermenting of organic materials, and finished product processing. Key factors need to be well controlled in different stages to ensure the quality and stability of organic fertilizers.

Compound fertilizer: It is made by chemical processes, usually by first reacting or mixing the raw materials with ammonia, and then processing them to produce new particles. Each fertilizer particle contains two or more nutrients from the three major elements of nitrogen, phosphorus, and potassium. At present, spray granulation, tower granulation, disc granulation, and rotary drum granulation are commonly used process methods in the production of composite fertilizers.

Compound fertilizer: Generally produced by physical mixing method, it only adds different types of raw materials (such as urea, ammonium chloride, ammonium sulfate, potassium chloride, diammonium phosphate, etc.) in a certain proportion according to demand, and is made through physical crushing, mixing, processing, and granulation. The production process level is relatively low.

  1. The quality and efficiency of fertilizers are different

Organic fertilizer: The particles have a uniform particle size and shape, making them easy to use and eliminating the need for secondary crushing. Secondly, it has high fertilizer efficiency, which can improve soil fertility and promote plant growth. In addition, organic fertilizer particles also have high stability and are not easily volatile or lost, which can reduce fertilizer waste and environmental pollution.

Compound fertilizer: In terms of particle appearance, it has a consistent and more uniform size, better physical properties, fewer side components, and better water solubility. In terms of nutrient content of particles, compound fertilizer has a higher nutrient content, each fertilizer contains multiple nutrients, and the content and release of nutrients are more balanced. In terms of fertilizer application efficiency, it is more balanced and stable, and the utilization rate of fertilizer efficiency is higher.

Compound fertilizer particles: There are often unstable physical properties, multiple side components, and varying particle sizes on the appearance, as well as unstable quality of raw materials, uniform distribution of nutrients in individual particles, and unstable water solubility. In terms of fertilizer nutrient status and performance in the field, compound fertilizer has lower nutrient content, uneven nutrient release, unstable fertilizer efficiency, and low fertilizer utilization rate.

  1. Compound fertilizer production line and organic fertilizer production line

The compound fertilizer production line is used to produce compound fertilizers that mix multiple nutrients. It consists of equipment such as fertilizer granulator, mixer, screening machine, packaging machine, etc. It can be adjusted and expanded according to needs. The compound fertilizer production line can mix different types and proportions of fertilizer raw materials together to produce granular, easy to store, and easy to decompose compound fertilizer products.


The compound fertilizer production line has advantages such as efficiency, automation, and environmental protection. According to the needs of crops, compound fertilizers with balanced nutrition and stable quality can be produced to improve the efficiency and yield of agricultural production. The compound fertilizer production line can also achieve environmental protection and resource conservation through the treatment and recycling of waste gas and wastewater.
