ซัพพลายเออร์ที่ผ่านการตรวจสอบแล้ว Chemical fertilizers are usually divided into two types: macro-element fertilizers and micro-element fertilizers. What are the macro-element fertilizers? Macro-element fertilizers are fertilizers that are absorbed and consumed in large quantities by crops, such as nitrogen fertilizer, phosphate fertilizer, potash fertilizer, calcium fertilizer, magnesium fertilizer, and sulfur fertilizer.
Microelement fertilizers are usually referred to as micro-fertilizers for short. Refers to fertilizers containing micronutrients, which are less absorbed and consumed by crops (compared to macronutrient fertilizers). Although crops require very little trace elements, they are as important to crops as macro elements and cannot be substituted for each other. The application of micro-fertilizers must be based on nitrogen, phosphorus, and potassium fertilizers to give full play to their fertilizer effects. At the same time, under different levels of nitrogen, phosphorus, and potassium, crops respond differently to trace elements. Generally speaking, low-yield soils are prone to lack of trace elements; high-yield soils, as the yield level continues to increase, crops' demand for trace elements will increase accordingly. Therefore, it is necessary to supplement the application of micro-fertilizers, but it would be wrong to attempt to reduce the application of macro-element fertilizers and only rely on the application of micro-fertilizers to obtain high yields.
