For spraying cereal crops or smooth-growing crops, add 0.1% of adhesive (such as washing powder, wash clean). Otherwise, the effect is not good.
For urea, the content of biuret can not be higher than 0.5%, otherwise it will easily damage the blade.
Different crop types require different concentrations of urea solution to be sprayed. Generally, cereal crops require a spray concentration of 1.5% to 2%, and when sprayed at the flowering stage, the concentration is lower. The spraying concentration of vegetables and cucumbers of leafy vegetables is 1% to 1.5%, and that of tomatoes is 0.3%. Apples, pears, grapes and other fruit trees are preferably 0.5%.
