There is a relationship between the fertilizers, and there are also contradictions. For example, if more phosphorus is applied, the excess available phosphorus will combine with the effective zinc in the soil to form a poorly soluble zinc phosphate precipitate, which will cause an effective zinc deficiency in the soil. Not only that, the excess available phosphorus will inhibit the absorption of nitrogen by crops, and will also cause boron deficiency and copper deficiency. Another example is the application of potassium fertilizer, which will reduce the absorption of nitrogen, magnesium, calcium, boron and zinc by crops. Lime is a kind of calcium fertilizer, but the excessive application of lime makes the soil alkaline, which will cause the lack of effective zinc, iron, manganese and boron in the soil. Even organic fertilizers should not be applied too much. Due to the excessive application of organic fertilizer, the microbes and crops in the soil will also have the contradiction of “striving nitrogenâ€, causing the soil to temporarily lack nitrogen for a period of time.
Partial application of crops and multi-application of simple fertilizers (such as urea, phosphate fertilizer, potassium fertilizer, etc.), I am afraid it is not an individual phenomenon. This not only wastes fertilizer, increases production costs, pollutes the environment, but also leads to the lack of certain effective elements of the crop. Therefore, when fertilizing crops, it is necessary to increase and increase according to the proportional relationship between various nutrient elements. The use of compound fertilizers and compound fertilizers is advocated because they are based on soil census results and crop fertilizer requirements, and the proportion of nutrient elements is relatively coordinated.
