In agriculture, the use of foliar fertilizers seems to have been an indispensable part to help plants receive the best nutrition. However, each type of fertilizer will have its own advantages, uses and notes. Foliar fertilizer also, if not used properly, it will have the opposite effect affecting the growth and development of plants. Today’s article we will exclusively share with you important information related to foliar fertilizers. Follow along with us.
Advantages of applying foliar fertilization
Using foliar fertilizers, plants will absorb nutrients through the stomata system on the leaf surface. Meanwhile, researchers have shown that leaves help in nutrient absorption efficiency up to 95%. Therefore, foliar fertilization will help the plant absorb quickly and receive more nutrients.
Foliar fertilizers often contain nutrients in macro- and intermediate forms. Although these elements do not play a major role in providing nutrients, in the soil environment, they are very few and even absent. Therefore, in order for the plant to receive enough nutrients, it is imperative to use more foliar fertilizers.
The ingredients in foliar fertilizers also have the ability to enhance growth regulation to help plants quickly branch, shoot, flower and set fruit. Especially, fertilizers also help limit the drop of young fruit, bring a more standard aesthetic appearance and help the tree to resist pests and diseases.
Cases that need to spray foliar fertilizer
- Soils with low levels of essential nutrients
Each type of soil will have its own problems, the source of essential nutrients for plants will also be at different levels. The foliar application of fertilizers helps plants receive essential nutrients that are not available or eliminated in the soil clean land have added certain nutrients but not enough to supply plants for a long time.
- The top layer of soil is dry
With soils characterized by aridity, it is certain that the useful substances in the soil will decrease, thus not providing enough of what the plant needs throughout the growing period. In this situation, foliar fertilization will give better results than foliar fertilization fertilize the soil.
- Roots are underactive during the reproductive period
During the reproductive stage, the root system will work less efficiently. At this time, the spraying of nutrients through the leaves will help the plant absorb a more abundant source of nutrients to compensate for the lack of nutrients from the roots. However, when you want nourish the leavesin some cases can still use the original fertilizer can still achieve the desired effect.
- Increase the amount of Ca in the fruit
There are many crops that often show a Ca disorder when fruiting (the inner part of the fruit and the bottom of the fruit is black rot). Therefore, farmers need to use foliar spray many times or spray directly on the fruit to limit the above situation.
Things to note when using foliar fertilizers
Farmers should clearly note one problem that foliar spraying is not the main method to provide nutrients to plants. The use of foliar fertilizers is just an additional form of support to provide nutrients that the roots cannot absorb from fertilizing through the soil. So root fertilizer and foliar fertilization depending on the stage will help support the best plant growth.
The ratio and nutrient composition in each fertilizer are not the same. Therefore, each type of crop will have nutritional requirements from one or more certain fertilizers at the allowable concentration. At the same time, each stage of plant growth, the purpose of use, the harvest of the crop for which the fertilizer is prioritized to use is also different.
Using a foliar fertilizer several times throughout the plant’s life is the best way to keep the plant getting enough and balanced nutrients. With a small amount of Ca and difficult to move during the nutrient cycle of the plant, frequent foliar spraying is essential.
Not because foliar fertilizers are used too much because they think it will be good for plants. When plants receive excess foliar fertilizer, it can affect the growth, development and reduce the quality of agricultural products.
When the plants are in bloom, foliar fertilizers should not be used, during heavy rain or too hot weather, it is also necessary to limit the use of fertilizers in this form.
Farmers should note that for plants with 2 cotyledons, foliar fertilization should be focused on the underside of the leaves. The amount of water when spraying ensures a wide distribution throughout the leaf surface.
Foliar fertilizer is not a growth stimulant, because in foliar fertilizer there are only nutrients that help plants grow in stages. Meanwhile, growth stimulants cause plants to grow quickly in a short time, skipping many important growth stages, causing poor quality of agricultural products, affecting users’ health.
Above are our shares about foliar fertilizers. Hopefully through this article you will somewhat better understand the things related to foliar fertilizers.
