Stop focusing only on NPK! What the soil lacks the most are medium and trace elements!
Since the application of chemical fertilizers, it has been used for decades. Every year and every season, the soil will have a large amount of nitrogen, potassium, phosphorus, and compound fertilizers. However, although the cost of agricultural inputs is increasing, the output and There is still no significant increase in quality, but a partial decline!
According to the statistics of the soil research report of the Academy of Sciences, the soil and regional distribution data of lack of trace elements in my country show that more than 50% of the soil in my country is deficient in trace elements, which directly leads to the fact that no amount of supplementation of chemical fertilizers (nitrogen, phosphorus, and potassium) can increase crop production. Reduced crop yields and lower quality agricultural products!
Because in the past few decades, large amounts or even excessive inputs of large amounts of nitrogen, phosphorus, and potassium fertilizers have been invested in my country's agricultural production, but the systemic supply of medium and trace elements has been ignored, resulting in an imbalance in the proportion of nutrients in the soil, coupled with crop output. The medium and trace elements in the soil are seriously deficient! Several situations of deficiencies of trace elements in the soil.
1. Decades of farming soil has little or no micronutrient nutrition.
2. The remaining part of the soil is limited to soluble trace elements. Because the soil is unhealthy and the aggregate structure is too poor, it has been completely solidified into the soil, resulting in the crops not being able to absorb it.
3. Even if micronutrient elements are supplemented, due to soil degradation, poor soil fertility, and changes in microbial communities, the supplemented nutrients cannot be effectively used and crops cannot absorb them.
Although there are few trace elements, they are essential elements!
Why is it called a required element?
1. Without this element, crops cannot complete the whole process from seed to seed formation.
2. If there is a lack of certain essential elements, there will be specific deficiency symptoms. Only after supplementing this element can the symptoms be relieved and disappear.
3. The element must have a direct nutritional effect on the crop, and its specific physiological function must be clarified.
Medium and trace elements are very important!
1. Increase crop yield
Due to the long-term excessive use of nitrogen, phosphorus, potassium and other large-element fertilizers in some farmlands, the soil quality has deteriorated, and the increase in production has been very limited. Targeted application of micro-fertilizers is an effective technical measure to increase the yield of medium and low-yield fields, and it is also an important means to maintain continuous increase in high-yield fields.

By increasing the application of medium and micro fertilizers, the needs of crops for various nutrient elements are met, so that the crops can grow and develop normally, so as to obtain ideal yields and benefits.
2. Improve crop quality
The application of medium and trace element fertilizers has greatly improved the inorganic nutrient balance of crops, not only greatly increased crop yields, but also greatly improved the quality of agricultural products, and effectively reduced the content of nitrite in agricultural products. Diseases can also be effectively prevented and treated.
The scientific application of micro-fertilizers not only meets the needs of crops for nutrient elements, makes them grow normally and fully mature, improves the quality of agricultural products, but also reduces the surplus of a large number of elements nitrogen, phosphorus and potassium, avoids waste of fertilizers, and reduces soil pollution.
3. Improve the utilization rate of chemical fertilizers
According to the law of minimum nutrients, supplementing medium and trace element fertilizers is beneficial to balance the ratio between large, medium and micronutrient elements, and has a good effect on promoting the absorption of nutrients by crops, instead of one-sided application of a certain element fertilizer, causing waste .
4. Reduce crop pests and diseases
Due to the application of trace element fertilizers, the various elements required by crops are supplied in a balanced and reasonable manner, which greatly enhances the ability of crops to resist disease, cold, high temperature, and drought. Existence, so that crops can grow healthily.
For example, after boron is applied to crops, it can promote the normal operation of sugar in the body and strengthen the resistance. The boron sugar complex is a complex with strong acidity, which makes the cell fluid reaction acidic and is not conducive to the growth of pathogens.
5. Reduce environmental pollution
Many soil and water sources are polluted, most of which are caused by excessive waste of nitrogen fertilizers. Increasing the application of medium and trace element fertilizers can make crops absorb various nutrients in proportion, effectively improve the utilization rate of fertilizers, and reduce the loss of fertilizers. environmental pollution and play a positive role in environmental protection.
6. Improve economic efficiency
Because the amount of trace elements is extremely "tiny", a relatively small price can be exchanged for greater economic benefits, and the input-output ratio is as high as 1:50~1:100, or even higher, while the input-output ratio of large chemical fertilizers is generally 1:5~1:10, or even lower. Therefore, adding micronutrients is a cost-effective investment!
In recent years, people's requirements for agricultural products have gradually shifted from quantity to quality. Therefore, the rational application of medium and trace element fertilizers can not only increase the yield, but also have a very obvious effect on improving the quality of agricultural products and can effectively enhance the resistance of crops to diseases, low temperature, high temperature and drought.
