1. Do not simply apply nitrogen, phosphorus and potassium macronutrient fertilizers
Among all the nutrients, nitrogen, phosphorus and potassium are the three elements that vegetables absorb more during growth, and their impact on vegetable yield is crucial. Some growers often only pay attention to the input of these three types of fertilizers during cultivation, and ignore the use of other fertilizers. Under the guidance of wrong concepts, using only nitrogen, phosphorus and potassium fertilizers is not enough to ensure the normal growth of plants! There are too many things missing in the soil, so we must consider them comprehensively. In addition to the three elements of nitrogen, phosphorus and potassium, we must supplement the missing trace elements in the soil, various acid mediators, such as fulvic acid, amino acids, and microbial flora that repair the soil environment.
2. What are the symptoms of excess potassium in apples?
Now the land has been cultivated for many years, and the content of nitrogen, phosphorus and potassium is not lacking. Due to continuous cultivation, the proportion of nitrogen, phosphorus and potassium absorbed by crops is relatively fixed. The higher the nitrogen, phosphorus and potassium content of fertilizers, the crops cannot absorb them all. The remaining nitrogen, phosphorus and potassium elements are deposited in the soil, causing the soil to become compacted, which is counterproductive. Crop fertilization emphasizes the three principles of balance. In summary, it is to supplement what is lacking, how much is lacking, and when it is lacking, when it is lacking.
3. Apply more fertilizers containing microbial agents
Microbial bacteria can decompose and digest the nutrients in the soil into substances that are easily absorbed, promote crop absorption, and loosen the soil. At the same time, it can release heat and increase ground temperature during the decomposition process. It can also quickly increase the beneficial bacteria in the soil, improve the effectiveness of trace elements in the soil, reduce the sodium salt content in the soil, and have the function of improving the soil.
4. Buy compound multifunctional fertilizers: Compound multifunctional fertilizers are the better
third-generation fertilizers at present. They can repair the soil environment, improve fertility, ensure all the nutrients needed for plant growth, improve soil pH, and supplement the missing microbial flora in the soil. Make the compacted soil loose, breathable, and lock water, and then achieve a high yield effect.
