There are many types of fertilizers, so where exactly do the differences between them lie?

China is a major agricultural country. With the long-term abuse of chemical pesticides, incalculable damage has already been done to the land. "Soil salinization," "compaction and desertification," "fertility imbalance" - our ecological environment is already in grave danger. For the sake of future generations, the state has begun to strongly advocate and support new green, efficient and healthy fertilizers. Various organic fertilizers keep emerging on the market, and their prices differ accordingly (microbial inoculant > bio-organic fertilizer > organic fertilizer). So how exactly should these new fertilizers be defined, and how should one choose?

Organic fertilizer

(NY-525-2012) - industry standard

Fertilizer that contains organic matter is called organic fertilizer. This kind of fertilizer can provide crops with a variety of inorganic/organic nutrients and improve soil fertility. Farmyard manure, oil cake fertilizer, biogas fertilizer and composted fertilizer all belong to organic fertilizer.

But organic fertilizer also has drawbacks that cannot be ignored. Its nutrient content is low, it is not easily decomposed, it takes effect slowly and its efficiency is low, so it cannot promptly meet the growth needs of crops. Especially at a time when agriculture is developing extremely rapidly, low productivity equals losing market competitiveness.

In addition, in terms of accumulation and use, organic fertilizer is also extremely inconvenient. Organic waste such as human, livestock and poultry manure and garbage is unsanitary material, carrying many pathogenic microorganisms or containing some toxic substances that contaminate crops. If not handled properly during operation, people can also be contaminated, causing harm to health. Most importantly, with the continuous development of modern animal husbandry, the feed eaten by farm livestock contains relatively many kinds of additives. These additives often contain a certain amount of harmful substances or heavy metals. These substances are excreted with livestock manure and accumulate, and once mixed into the soil they pollute the environment and affect people's health.

Bio-organic fertilizer

（NY-884-2012）- Industry standard

Bio-organic fertilizer is a kind of fertilizer produced by harmless treatment of traditional organic fertilizer. It is mainly made by combining organic materials such as livestock and poultry manure and crop straw that have undergone decomposition and purification treatment.

Compared with traditional organic fertilizer, bio-organic fertilizer, through high-temperature decomposition, eliminates most pathogenic bacteria and insect eggs, thereby ensuring crop health and environmental protection, while also reducing the occurrence of pests and diseases, and it is relatively convenient to use and handle.

Agricultural microbial inoculant

(GB 20287-2006) - national standard

Specific microorganisms and effective bacteria are produced industrially and multiplied, then porous materials such as peat and vermiculite are used as fermentation liquid processed into live bacterial preparations for attaching and adsorbing the bacterial bodies. This is calledmicrobial inoculant。

This type of agricultural microbial inoculant fertilizer can effectively directly or indirectly improve the soil, restore soil fertility, and can also prevent soil-borne diseases, maintain the microbial balance in the root system and degrade harmful substances. Microbial inoculant fertilizer specially used in agriculture can effectively increase crop yields, improve the quality of agricultural products, and reduce the amount of chemical fertilizer used, thereby lowering costs. At the same time, it can improve the soil and protect the ecological environment. It is currently the most highly recommended new type of agricultural fertilizer.
