In today’s society, environmental protection and sustainable development have become the focus of global attention. With the continuous development of agricultural production, the excessive use of traditional fertilizers has led to a series of environmental problems such as soil degradation, water pollution, and ecological imbalance. Therefore, seeking environmentally friendly and sustainable fertilizer production methods is particularly important. In this context, humic acid fertilizer, as a new type of environmentally friendly fertilizer, is gradually receiving attention.
1、 The concept and sources of humic acid
Humic acid is one of the main components of organic matter in soil, mainly derived from the decomposition and transformation of plants, animals, and microorganisms. Humic acid is not only present in soil, but also widely present in peat, coal, and other organic materials. Its molecular structure is complex, with strong adsorption, ion exchange, and buffering capabilities, which can effectively improve the physical and chemical properties of soil.
2、 The production process of humic acid fertilizer
（1）Raw material selection
The production of humic acid fertilizers usually uses raw materials rich in humic acid, such as peat, peat, lignite, etc. These raw materials are not only rich in humic acid, but also contain abundant trace elements and nutrients, which can provide comprehensive nutrition for plant growth.
（2）Humic acid extraction
The extraction methods of humic acid mainly include chemical and physical methods. Chemical methods usually use chemical reagents such as sodium hydroxide and ammonia water to extract humic acid through dissolution and precipitation. The laws of physics are more environmentally friendly through methods such as hot water extraction.
（3）Granulation and drying
The extracted humic acid is usually in liquid form and needs to be granulated and dried for storage and application. The granulation process can be carried out through spray drying, drum granulation and other methods to ensure that the fertilizer particles are uniform and easy to apply.
（4）Packaging and Storage
After production, humic acid fertilizers need to be properly packaged to prevent moisture and pollution. The storage environment should be kept dry, ventilated, and avoid direct sunlight to ensure the stability and effectiveness of fertilizers.
3、 The advantages of humic acid fertilizer
（1）Improve soil structure
Humic acid fertilizer can effectively improve the physical properties of soil, increase soil permeability and water retention capacity, and enhance soil particle structure. This is of great significance for improving the root development and water use efficiency of crops.
（2）Improve plant nutrient absorption
Humic acid has good ion exchange ability, which can promote the release of nutrients in soil and the absorption of plants. Research has shown that crops treated with humic acid fertilizers have significantly improved nutrient absorption efficiency and healthier growth.
（3）Enhance plant stress resistance
Humic acid can enhance the stress resistance of plants and improve their adaptability to adverse environmental conditions such as drought and salinity. This plays an important role in addressing climate change and ensuring agricultural production safety.
（4）Environmental Protection and Sustainable Development
The production process of humic acid fertilizer is relatively environmentally friendly, which can reduce dependence on chemical fertilizers and lower the risk of soil and water pollution. At the same time, the use of humic acid fertilizers helps to restore the ecological functions of soil and achieve sustainable agricultural development.
4、 Application of Humic Acid Fertilizer in Agriculture
（1） Crop cultivation
Humic acid fertilizers are widely used in the cultivation of various crops, including grain crops, cash crops, and fruits and vegetables. Research has shown that crops treated with humic acid fertilizers generally have higher yields and better quality.
（2）Ecological agriculture
In ecological agriculture, humic acid fertilizer is considered an important soil amendment. By applying humic acid fertilizers reasonably, the ecological balance of soil can be effectively restored and maintained, and biodiversity can be promoted.
（3）Organic Agriculture
With the rise of organic agriculture, humic acid fertilizer has become one of the important organic fertilizers. Its natural and harmless properties make it an indispensable fertilizer choice in organic agriculture production.
