Top Ten Misunderstandings in Using Boron Fertilizer

In 1923, K. Warington discovered that boron is an essential element for plants. The content of boron in crops is generally 2/10,000, 3 to 1% by dry weight. Among them, leguminous and cruciferous crops have the highest content, while gramineous crops have low content. Among the various organs of crops, flowers and leaves have the highest content, followed by stems, roots and fruits, and seeds have the lowest content.


Boron is not a component of various organic substances in crops, but it can enhance some important physiological functions of crops. If the supply of boron is sufficient, the plants will grow luxuriantly, the seeds will be full, the root system will be good, and the harvest will be guaranteed; on the contrary, if the supply of boron is insufficient, the crops will be severely reduced or even lost.

Misunderstanding 1. Boron has only a significant effect on high-growth crops.


Boron plays a vital role in crop reproductive growth, and all crops require only different amounts of boron. High boron demand crops rape, cotton, fruit trees. Vegetables require a lot of boron, and rice, corn, and wheat require less boron, but even for crops that require less boron, symptoms of boron deficiency can seriously reduce yields. During the 60 years of boron use, the application of boron fertilizers to 132 crops in more than 80 countries can significantly increase yields and improve quality.


Misunderstanding 2. There is no shortage of boron in crops, so there is no need to apply boron fertilizer.


A large number of experiments have confirmed that crops have a demand for boron shadow storage. Even if there are no symptoms of boron deficiency, the application of boron fertilizer can greatly increase the yield.


Misunderstanding 3. Crops only need to apply boron once a year.


Crops need a constant supply of boron. Even if the supply of boron is interrupted for a short time, crop yields and quality will be affected. Therefore, the application of boron fertilizer should be combined with foliar fertilizer, and foliar spray should be applied in small amounts frequently.


Misunderstanding 4. Boron fertilizer mainly adopts base application method


The boron fertilizer introduced in early agricultural production is industrial borax, which can only be applied at the base, and cannot be sprayed or the effect of spraying is not good. The combination of soil basal application and foliar spray application of boron fertilizer has the best effect.


Misunderstanding 5. When crops with high boron demand and low boron demand are rotated, the application of boron fertilizer will affect subsequent crops.


Studies have confirmed that even if broccoli is applied several times more than the recommended dose during the rotation of cauliflower and beans, it will not affect the next crop of beans.


Misunderstanding 6. Lack of boron in crops has only a small impact on yield or quality.


Lack of boron in crops will cause the loss of all yields, and the high-end market value of all fruits. In some parts of the United States, farmers will pull out crops once they find they are deficient in boron.


Misunderstanding 7. Boron is a microfertilizer, which is not as important as N, P, and K fertilizers.


Boron has an irreplaceable effect on the flowering and fruiting of crops. The role of N, P, and K cannot replace boron. The concept of balanced fertilization: stabilize nitrogen, reduce phosphorus, increase potassium, and supplement micronutrients (boron, silicon, calcium, etc.), so boron and nitrogen, phosphorus and potassium are equally important. Only pay attention to the application of nitrogen, phosphorus and potassium fertilizers and ignore the application of boron fertilizers. Productivity and quality will decline, and inputs of nitrogen, phosphorus, potassium fertilizers, seeds, and pesticides will also be lost.


Misunderstanding 8. Boron and magnesium fertilizers can replace boron fertilizers


Boron-magnesium fertilizer is commonly known as boron mud. Its main component is magnesium sulfate, which contains less than 0.2% boron. It is only leftovers from the production of magnesium sulfate. It cannot be compared with borax and high boron content. Granular boron is 75 times the content, boron and magnesium fertilizers cannot supplement the boron needed by crops.


Misunderstanding 9. Multi-element foliar fertilizer is better than single trace element boron


Boron is the most important trace element for flowering and fruiting crops. Most economies, fruit trees and vegetable crops are in high demand. The trace boron contained in various foliar fertilizers cannot meet the crop's demand for boron. Therefore, single boron supplementation is better than applying multiple elements to boron-determining crops.


Misunderstanding 10. When buying boron fertilizers, do not look at the pure boron content of the product.


Many inferior or counterfeit boron fertilizers do not indicate the pure boron content according to the national requirements, but only vaguely indicate the so-called purity of the product. Even if the 100% pure garbage and waste is still garbage and waste, you must clearly recognize the product when purchasing the product and indicate that it has pure boron content.
