Zusammenfassung:The selenium liquid composite fertilizer consists of nitrogen, phosphor, potassium and the trace elements of magnesium, zinc, copper, manganese, boron and selenium. Th preparation method is that compounds containing nitrogen, phosphor and potassium are mixed and prepared with the chemical compounds of the trace elements of magnesium, zinic, copper, manganese, boron, molybdenum and sulfur into water solution, then added with industrial selenium dioxide and stirred to dis solve, regulated by ammonia water to make its pH value as 6.0-6.5. Advantage: high efficacy, quick results, non-toxcity, low cost, sfety, good quality and wide application range.
