Six major misunderstandings about foliar feeding of crops to avoid
Foliar feeding, also called topdressing outside the roots, is a fertilization measure that cannot be ignored in fruit tree production. This method saves labor and effort, takes effect quickly, and has a high utilization rate. Within 24 hours, 80% of the sprayed fertilizer can be absorbed. For fruit trees such as apples, pears, and hawthorns, spraying during the flowering period can increase the fruit-setting rate; spraying during the leaf and fruit growth periods can promote...

Foliar feeding cannot be done at will; only by mastering the correct method can it be effective
Foliar topdressing of vegetables is a fertilization method in which fertilizer is dissolved in water and sprayed onto the leaf surface. This method is simple, convenient to apply, low in cost, quick in effect and high in benefit. It is especially suitable for topdressing trace elements and plays a positive role in increasing vegetable yield and quality, but it must be done scientifically and reasonably. 1. Fertilizer types...

What is the correct method for foliar feeding of fruit trees?
1. Types, timing and amounts of spray fertilizer. Nitrogen fertilizer should generally be used in the early and late stages of fruit tree growth, appropriately combined with phosphorus and potassium fertilizers. An appropriate spray concentration can effectively promote new shoot growth, increase fruit yield, and benefit flower bud differentiation. The concentration for urea is 0.2%-0.3% in the early stage and 0.3%-0.5% in the late stage; decomposed...

Can urea actually be used to feed livestock?
How can potassium fertilizer be applied to late rice to increase yield? The yield-increasing effect of potassium fertilizer on late rice has become increasingly obvious, especially for hybrid late rice. In recent years, with the large-scale planting of hybrid late rice. In recent years, with the large-scale planting of hybrid late rice, potassium deficiency responses are more sensitive than in conventional rice, and the effect of potassium deficiency on late rice yield is more obvious. Late rice is prone to...

What are the precautions for foliar feeding of crops?
What should be noted when doing foliar feeding of crops? Please give an introduction. There are many types of fertilizers used for foliar feeding of crops, but some are suitable for foliar spraying and some are not. For example, urea, potassium dihydrogen phosphate, borax, ammonium molybdate, zinc sulfate, etc. can all be sprayed on the leaves. Some fertilizers containing chloride ions, volatile fertilizers and poorly...
