What types of chemical fertilizers are there? Understanding common fertilizer classifications in one article
When it comes to chemical fertilizers, everyone must be familiar with them by now. They are made through chemical and artificial processes to contain one or several nutrient elements needed for crop growth: fertilizers. Among them, nitrogen, phosphorus and potassium fertilizers are the most basic fertilizers for crop growth. Their compositions are relatively simple, their nutrient content is very high, and their fertilizer efficiency is very good. They are now widely used on various crops. So what are the common types of chemical fertilizers today? Let's take a look together!
1. Nitrogen fertilizer
Nitrogen is the main element that makes up proteins, and proteins are the basic substances in the composition of cell protoplasm. Applying more nitrogen fertilizer can promote the formation of proteins and chlorophyll, making leaves dark green and increasing leaf area, promoting carbon assimilation, and helping increase yield and improve quality. Common nitrogen fertilizers include ammonium sulfate, ammonium bicarbonate and urea. These nitrogen fertilizers will not damage soil structure even when applied year after year during crop cultivation.
2. Phosphorus fertilizer
Phosphorus is an indispensable element for forming nucleoproteins, lecithin and other substances. The phosphorus element can accelerate cell division, prompt faster growth of roots and aboveground parts, promote flower bud differentiation, advance maturity, and improve fruit quality. Common phosphorus fertilizers include superphosphate and triple superphosphate, generally used as foliar topdressing or base fertilizer, so that crops can absorb them directly more easily.
3. Potassium fertilizer
The nutritional effect of the potassium element can increase the intensity of photosynthesis, promote the formation of starch and sugar in crops, enhance crop stress resistance and disease resistance, and also improve crop absorption and utilization of nitrogen. Common potassium fertilizers include potassium chloride and potassium sulfate, often used as base fertilizer and topdressing. For acidic soil, they can also be used together with lime and organic fertilizers.
4. Compound fertilizer
Compound fertilizer refers to chemical fertilizer that simultaneously contains the three major elements nitrogen, phosphorus and potassium, or contains only any two of them. It has advantages such as high nutrient content, few secondary components, uniform nutrient release, stable and long-lasting fertilizer efficiency, and easy storage and application.
Common compound ingredients include ammonium phosphate, nitrogen-phosphorus-potassium compound fertilizer and potassium dihydrogen phosphate, often used as base fertilizer or foliar topdressing, with very good results.
At this point, the introduction to common types of chemical fertilizers ends here. If everyone wants to grow high-yield and high-quality crops, it is recommended to choose reasonable fertilizer varieties and master professional fertilization techniques. I hope this article is helpful to everyone.
