20-20-20+TE indicates that the total nitrogen content of this brand of water-soluble fertilizer is 20%, the content of phosphorus pentoxide is 20%, and the content of potassium oxide is 20%. TE says that trace elements are contained in fertilizers. Manufacturers generally specify the content and morphology of trace elements in fertilizers in their technical manuals. The added trace elements mainly include boron, iron, zinc, copper and molybdenum, among which the addition of chelated trace elements is optimal.
Since the absorption and utilization efficiency of chelated trace elements is about 40 times that of inorganic trace elements and it is very safe, even if the amount is low, there is no need to worry about the symptoms of nutrient deficiency in crops. Of course, trace poisoning is not possible. Not to worry about different elements being mixed together can cause tamper resistance.
