What are the high-quality categories of new compound fertilizers? A detailed introduction
Compound fertilizer is a commonly applied fertilizer in agricultural production. It is well known for its excellent fertilizing effect on crops, especially for increasing crop yields. It has the characteristics of high nutrient content, high utilization rate, and convenient application. However, there are now many categories of compound fertilizer on the market. Next, let us learn about several new categories of compound fertilizer together. Their fertilizing effects are all very good.
1. Urea-formaldehyde compound fertilizer
Urea-formaldehyde compound fertilizer is also a relatively early new fertilizer variety. Its main mechanism is that urea and formaldehyde react at high temperature to form two colloids, 1-methylene-2-urea and 2-methylene urea, which are then combined with monoammonium phosphate and potassium fertilizer for granulation. By extending the reaction time of nitrogen transformation, the fertilizing effect is prolonged, and the requirements for controlling the production process are relatively high.
2. Humic acid compound fertilizer
Humic acid compound fertilizer has always been active in the field of new fertilizers. Because raw materials are easy to obtain and cheap, humic acid compound fertilizer can be regarded as a relatively ordinary new compound fertilizer. It is inexpensive and of good quality, with high cost performance, and is very popular among farmers.
3. Seaweed compound fertilizer
Seaweed compound fertilizer uses algae growing in the ocean as raw material. Through certain technologies, the effective components in seaweed are extracted. In combination with the explosive growth of aquatic plants caused by water eutrophication in recent years, large amounts of seaweed need to be treated, and the application fields of seaweed products have continued to expand, ultimately combining with fertilizers. Seaweed products contain many types of substances and mainly rely on the sugars and polyphenols they contain to regulate plant growth. At the same time, they contain some trace elements and amino acid substances that can provide part of the nutrition for crops. The final effect is similar to that of humic acid, and it is a relatively complex and comprehensive effect.
4. Amino acid compound fertilizer
Many types of amino acids are promoted in the fertilizer field. On the one hand, the role of amino acids is biological regulation; on the other hand, they can directly serve as nutrients for plants, and their effect is also relatively comprehensive.
5. Coated fertilizers
As the earliest new fertilizers, coated fertilizers have already developed relatively maturely, mainly including sulfur coating, fertilizer coating fertilizer, and resin coating. Resin coating has the best and most stable effect but is relatively expensive. For different crop types, temperatures, and hydrological conditions, the controlled-release time and formula of coated fertilizers need to be adjusted accordingly in order to produce a very good fertilizing effect.
At this point, I believe everyone has a deeper understanding of compound fertilizer. Farmer friends who grow crops will certainly often need to use compound fertilizer. The above categories are all very good and are very useful for increasing crop yields.
