High-yield sulfur fertilizer for garlic
Garlic is a sulfur-loving crop. Allicin is mainly a disulfide compound. Most of the proteins in garlic contain sulfur, which plays an important role in improving the quality of garlic. At the same time, the study shows that the nitrogen and sulfur absorbed by the plant can get the most effective effect only when the fertilizer Nhammer S is close to the optimal value. In garlic, the content of Nipple S is about 12cm 1. The utilization rate of sulfur in calcareous soil in the north is 2%-3%, and it is easy to be fixed as calcium sulfate, and the nitrogen utilization rate is 30%-35%. The best Nmax S is 4amp 5. Sulfur can not be reused in garlic.
