The effective boron increases with increasing pH between pH 4.7 and 6.7, but the effective boron decreases with increasing pH between pH 7.1 and 8.1.
2. Soil organic matter In summary, when the soil organic matter is increased, the effective boron in the soil is correspondingly increased; the topsoil is rich in organic matter and the effective boron content is also high. Because organic matter has an adsorption effect on boron, when the organic matter is increased to a certain amount, it will cause a decrease in effective boron.
3. The relationship between boron and water precipitation and evaporation cause soil water movement, which also affects the growth and decline of soil boron. Analysis of the difference in available boron content in different precipitation areas indicates that the soil available boron content is also lower in areas with more precipitation, and the effective boron content is higher in areas with less precipitation. However, the effective boron in the soil enters the plant body by mass flow. Therefore, when the soil is dry, the amount of boron absorbed by the crop roots is reduced, which is easy to cause boron deficiency.
