Before explaining the types of agricultural fertilizers, let’s first give you some knowledge about fertilizers. Do you know “what is fertilizer” and “where does fertilizer come from”? This is an important knowledge that you need to understand about the classification of agricultural fertilizers. The composition of any knowledge starts from the most basic knowledge. Fertilizers are a very core part of the agricultural planting industry.
Substances that can provide nutrients for plant growth and development can be understood as agricultural fertilizers. As for the types of fertilizers, there are many classifications. The most common classifications are organic fertilizers and inorganic fertilizers. The nutrients they contain are mainly nitrogen, phosphorus, potassium and other three elements, but there are also some trace elements. During use, fertilizers can be used as direct or indirect nutrients to crops, promote crop growth, increase yields, improve crop quality, etc. In addition, fertilization can improve the structural environment of the soil, which has a continuous and stable effect on crop growth.
Where does agricultural fertilizer come from? Fertilizer is also a process of material circulation in nature. For example, the straw used for planting is not fertilizer itself, but needs a crushing and fermentation process to form fertilizer, and there is also organic fertilizer. There are other fertilizers, nitrogen fertilizer, which can be obtained from the atmosphere and is called nitrogen fertilizer in nature. When it rains or thunders, you can sometimes smell the smell of nitrogen fertilizer, which can be smelled in reality.
In terms of function, agricultural fertilizer is to promote crop growth and increase the yield of crop production. There are also many types of fertilizers on the market. For crop planting, when choosing fertilizers, it is necessary to choose fertilizers with appropriate functions based on the actual situation of crop growth and the type, characteristics, composition and efficacy of the fertilizer itself. The basic knowledge of the functions of these fertilizers is the key to the use of fertilizers.
Classification of agricultural fertilizers
① Organic fertilizer: For the term organic fertilizer, it is a written term. We are accustomed to calling farmyard manure organic fertilizer. There is nothing wrong with this point, but it is just a one-sided understanding. Generally speaking, farmyard manure is just a type of organic fertilizer, and this understanding is more correct. In practice, organic fertilizer is divided into traditional organic fertilizer and commercial organic fertilizer. This traditional organic fertilizer is often called farmyard manure, which mainly includes fertilizer made from human, livestock and other animals and crop straw. And this commercial organic fertilizer is organic fertilizer formed by a series of equipment processing.
②Inorganic fertilizer: Inorganic fertilizer can be understood as chemical fertilizer. It uses a certain chemical synthesis method to make the components of different elements through chemical reactions, and then through a series of procedures to form fertilizers with different contents. And this fertilizer is also more common. Every time crops are topdressed, they are basically purchased. Chemical fertilizers, especially corn topdressing, are mostly used for nitrogen fertilizer. It is the representative of chemical fertilizers, and its usage rate is very high.
③Biological fertilizer: Biological fertilizer can also be understood as bacterial fertilizer. For this fertilizer, its main purpose is to improve the physiological structure of the soil, especially when the soil is saline and alkaline, most of them will use such biological fertilizers. It can effectively improve the activity of biological bacteria in the soil, so that the oxygen content in the soil is greatly increased, so that the soil will maintain an activity. However, the main feature of using biological fertilizers is temperature. High temperature will reduce the activity of biological fertilizers and lose their original effect. This is mainly used in the greenhouse sterilization process. It must be used after the greenhouse is finished. It must not be applied before the greenhouse is finished, otherwise the biological fertilizer will be wasted in vain.
For the entire agricultural fertilizer, the three major classifications of fertilizers are like this. If you want to thoroughly understand the efficacy and characteristics of each fertilizer, it is not easy to understand at this point, especially the current chemical fertilizers. There are too many types of fertilizers sold on the market. There will be a very large gap in the element content of fertilizers produced by different manufacturers. There may be dozens or hundreds of companies producing the same type of fertilizers. There may be the same fertilizer effect, but there will be different names. For the classification of fertilizers, it can only be simply classified from a general direction. The fertilizers of different manufacturers can be seen in the specific instructions. I hope to read the instructions of the fertilizers before using them to reduce unnecessary troubles in the later stage.
