Sulfur powder can prevent soil alkalization. How is this achieved? Today I will talk to everyone about it.
Sulfur powder should be evenly sprinkled on the ground according to the calculated application rate, and manually or mechanically turned 30cm deep to mix the sulfur evenly with the soil that needs improvement. The application of sulfur should be carried out one year before planting, and the effect in that year is not significant. The improvement effect of the entire park is good, and in order to reduce costs, planting ditch improvement or planting improvement can also be adopted. Generally, reducing the pH value is carried out in conjunction with other soil improvement methods such as increasing organic matter. Therefore, the currently widely used method in China is to improve the planting ditch or improve the planting.
The low-cost way to reduce soil pH is to add sulfur powder to the soil, which is converted into sulfuric acid by soil bacteria, thereby reducing the soil pH value. If the soil pH value is greater than 5.5, reduce the soil pH value to 4.5 by adding sufficient agricultural sulfur. Spring mixed use has a good effect. Agricultural powder can also be converted into sulfuric acid through soil bacteria, reducing soil pH value.
In addition to adjusting the soil pH with sulfur powder, adding acidic peat can also effectively lower the soil pH. The mixed use of peat and sulfur has a better effect. In addition, soil covering with sawdust, pine bark, application of acidic fertilizers, and application of crude tannic acid all have the effect of reducing soil pH value.
