4 Fertilization Techniques to Give Foliar Fertilizer

Plants extract their food from the soil with the help of their roots, and for a crop to grow and produce, it must originate in nutrient-rich soil. The primary fertilization is to give fertilizer into the soil that contains the nutrients needed for crop plants, but research by agricultural engineers has proven that some minerals are not well absorbed from the soil level.

They include boron, magnesium, zinc, copper, iron, manganese and other minerals that are generally called “microelements”. It was found that these elements necessary for plant metabolism are more easily absorbed by the leaves, and thus foliar fertilization appeared.

Unlike basic fertilizers, foliar fertilizers are applied by spraying and below we present some management techniques that ensure maximum efficiency.

Application with other solutions

Foliar fertilizers are concentrated substances that are combined with water to obtain solutions that are sprayed on plants. It is very stable, so it retains its properties in combination with other solutions and at the same time does not affect the effectiveness of other active substances. This property is called miscibility and allows to combine foliar fertilizers with other solutions used for plant protection.

For example, Agricover foliar fertilizer can be used in combination with insecticides, herbicides or fungicides, in a single spray.

Addition to basic fertilizer

Foliar fertilizers are not designed to replace traditional fertilizers, but to supplement them and provide plants with nutritional supplements.

Thus, you can not hope for a good result if you use only foliar fertilizers for fertilizing. They do not contain all the essential nutrients, so there will be a significant deficiency that can harm the entire crop.

The rule of thumb is to carry out basic fertilization according to the established calendar, and then during the vegetation period they are sprinkled with foliar fertilizers.

They act as a food supplement for plants, accelerating the growth process and increasing their resistance to diseases and pests.

Spraying during periods of no rain

Like any spray, foliar fertilization should be done during a rain-free period. It takes a certain amount of time for the nutrients to be absorbed into the leaf tissues. Under these conditions, it is easy to understand that rainfall in this time period can reduce or even cancel the effect of fertilization.

For the same reason, crops are not irrigated for a few days after foliar fertilizer administration. It is equally important that the leaves of the plants are not wet when applying the remedy.

Spraying at the optimum period

Taking into account the fact that the absorption of nutrients is carried out at the foliar level, fertilizers in this range are used in more advanced periods of plant development. The more leaves grow, the greater the absorption surface, and the faster the effect of the treatment will be felt.

Foliar fertilizers have an effect at any stage of development, but administering them early is not very profitable, because a good amount of solution will be lost.

Instead of reaching the leaves, it will pour most of it into the soil. From this level it will not bring any benefit, since foliar fertilizers are not absorbed by the root.

The alternative is to fertilize more often when the leaves are sufficiently developed, and any nutrient deficiencies will be filled quickly.

By applying these techniques, crop plants will get all the necessary nutrients in sufficient quantities. If at the same time they benefit from good hydration, then there are all the prerequisites for obtaining a rich harvest, of the highest quality.
