Foliar fertilizer effect is good, spray concentration is how much
The concentration of urea cereals in general is 1%-2%; the concentration of vegetables, fruits, etc. is 0.5%-1%; the concentration of seedlings in seedlings can not be higher than 0.2%. Note that when the content of biuret in urea exceeds 1%, it is toxic to crops and cannot be sprayed.
Potassium dihydrogen phosphate commonly used spraying concentration of about 0.3%; preparation method is to take 300 grams of potassium dihydrogen phosphate plus 100 kilograms of water, fully dissolved after spraying. Urea and potassium dihydrogen phosphate can be used with the distribution.
Zinc sulfate is commonly sprayed at a concentration of 0.1% to 0.2%; a small amount of lime solution is added to the solution before spraying.
Superphosphate commonly used concentrations 1% to 3%. After the superphosphate was added with water, it was stirred well, allowed to stand for 24 hours and then filtered, and the supernatant was taken.
The common concentration of ferrous sulfate 0.2% ~ 0.3%. Due to the poor flow of iron, several shots should be made and the spray should be even.
