Usage of potassium dihydrogen phosphate on soybean

Soybean leaf fertilizer absorption ability is very strong, therefore, soybean foliar topdressing, with less fertilizer, quick effect, high efficiency, promote early maturity and other characteristics.

200~400 grams of potassium dihydrogen phosphate was used to mix seeds with Xingxing water during soybean sowing. Coated, drum in seedling stage, early flowering, seed each spray a dihydrogen phosphate, potassium dosage for every 400 grams of potassium dihydrogen phosphate, water per acre about 50 kilograms, practice has proved that this method can improve the soybean kernel weight 0.25 ~ 0.3 grams, the average per mu yield increases of more than 6%, if we can match with 400 ~ 500 grams of urea water 50 kg/mu, effect is better.
