3, store in a cool and dry place, and keep away from children.

Factors affecting soil available boron:

1. When PH is between 4.7 and 6.7, boron has the highest availability, while when PH is between 7.1 and 8.1, boron availability decreases with the increase of PH. The availability of boron in acid soil is high, but it is easy to lose by leaching. If a large amount of lime is applied, the availability of boron will be reduced and boron deficiency will result.

2, soil texture, soil texture affects the movement of boron in the soil. In the adsorption of the clay, more available boron can be maintained; In light soil, boron is easy to be leached, which reduces water-soluble boron. Therefore, boron deficiency tends to occur in light soils.

3. Soil organic matter. General texture affects boron availability in soil because boron bound to or immobilized by organic material can be released after the organic material decomposes.

4. Climatic conditions. Drought reduces the availability of boron in soil. In wet and rainy areas, boron loss is often caused by strong leaching and the content of available boron is reduced.

5. Crop types. According to the experiment, under the condition of mild and moderate boron deficiency, the yield of applying borax fertilizer was as follows: rape 51.%, wheat 14.6%, early rice 9.4%, late rice 13.7%.
