1.How does boron element exist in soil?

Boron mainly exists in the form of boric acid (H3BO3) in soil. This is also the form in which it is absorbed by the roots of plants. However, the absorption and utilization efficiency of boron by plants is influenced by different factors, including soil pH value, soil moisture content, and levels of calcium and nitrogen in the soil. In addition, excessive rainfall or irrigation can also filter out boron from the soil. Boron enters the soil through the decomposition of organic matter in the soil. The texture of the soil also affects the absorption and utilization of boron. Especially in sandy soils with low organic matter content, the deficiency of this element becomes particularly significant.

2.What are the factors that affect boron absorption and utilization in plant?

When applying boron to soil, soil quality is very important. For boron deficient soils with high clay or organic matter content, or soils that have been lime treated, it is recommended to apply higher doses of boron. This is because the adsorption of boron by the soil makes it difficult for plant roots to absorb boron.

The pH value of the soil can also affect the absorption of boron. A pH value between 5 and 7 is the ideal range for crops to absorb boron, under which most of the boron remains in an undissociated boric acid state. If the pH value is between 6 and 9 above this range, boron will be adsorbed by the oxides of iron and aluminum. In calcareous or high pH soils, boron will combine with carbonates, precipitate in the form of calcium borate, or be adsorbed into calcium carbonate, which plants cannot absorb and utilize.

Generally speaking, most of the boron required by plants is provided by organic matter. The soil conditions favorable for plants to obtain boron through organic matter decomposition are high temperature, soil moisture, microbial activity, and soil permeability.

Soil moisture may become a limiting factor for plants to absorb boron. Boron exists in soil solutions. Under dry conditions, there is less water in the soil, so the roots of plants cannot absorb boron. In addition, drying reduces the mineralization of organic matter, further reducing the absorbability of boron.

Heavy rainfall can lead to leaching risks, especially in sandy soils where boron may leach out from plant roots, which is more pronounced in non lime soil.

 3.Where are the symptoms of boron deficiency manifested?

Once absorbed by the root system, boron is transported unidirectionally from the root system to the aboveground part of the plant's xylem. And in the phloem responsible for transporting nutrients produced by leaves to other parts of the plant, boron is considered to be actually immovable. This means that boron deficiency symptoms occur at the growth points of young tissues.

 Symptoms of boron deficiency: Leaves become brittle, thickened, and the surface may be rough, wrinkled, and some may turn yellow, resulting in yellowing.

4.What are the functions of boron in plants? Boron is key to achieving various plant functions, including:

ma membrane stability

(2) Nucleic acid metabolism

(3) Sugar delivery

(4) Organizational differentiation

(5) Root elongation

(6) Synthesis of phenolic compounds

(7) Biological nitrogen fixation

(8) Pollen tube growth

5.What are the sources of boron fertilizer?

The boron content of most boron fertilizers is about 10%. However, the form of the product can affect the absorption rate of boron. The main sources of boron include pyroxene, sillimanite, hydroborite, and hornblende. In addition to the differences in characteristics between different ores, there are also differences within the same ore group. The production process can affect the solubility of boron fertilizer applied in the field, thereby affecting the plant's absorption rate of boron. Therefore, although different products may contain similar boron content, there may be significant differences in the boron absorption rate of plants.

For example: boron sodium calcium stone, the two commonly used manufacturing processes are calcination or acidification. Calcination uses high-temperature drying raw materials with the aim of increasing the boron content in fertilizers through dehydration. Although the boron concentration of these fertilizers is usually high, about 12-15%, their solubility is usually low, which means that boron is not easily absorbed by plants.
