Why can the end of tea be used as fertilizer, is there any value in developing fertilizer? It was determined that the waste tea contains 4.16% nitrogen, 0.43% phosphorus pentoxide, 1.44% potassium oxide, 28.1% organic carbon, and a carbon/nitrogen ratio of 6.19. After tea slag stacking, the content of ammonium nitrogen and nitrate nitrogen Rapid increase, so the tea slag or tea dried tea is applied to the soil after fermentation, not only can improve the soil fertility, improve the soil structure, but also can inhibit ammonium sulfate, urea and other ammonium nitrogen fertilizer nitrification, reduce the loss of inorganic nitrogen fertilizer, It is a good organic fertilizer.
