Some farmer friends find that the effect is very good after using foliar fertilizer, and some farmer friends find that the effect is very poor when using foliar fertilizer, what is the reason for this?

The onset time of foliar fertilizer is generally 5-7 days after use, so when using foliar fertilizer, depending on the condition of the crop, it is necessary to start using it 5-7 days in advance.

For farmers with rich planting experience, the nodes can generally be grasped very well, and the reason for the poor effect of foliar fertilizer is mainly because of the concentration problem. Especially at present, many bad manufacturers in order to publicize their products for profit, exaggerated publicity, can be mixed with 600 pounds of water foliar fertilizer let growers with 1200 pounds of water, the effect can be good to go?
