What to Do About Fertilizer Burn in Eggplants? Latest Remedial Methods Explained
Eggplant is a very common vegetable in our country, and because it has a very large market demand, the current planting area of eggplant in our country is still relatively large. And when we grow eggplants, various problems still often arise that affect the growth of eggplants. And fertilizer burn is one of them, so what causes fertilizer burn in eggplants? And what should be done about fertilizer burn in eggplants? Below, the editor will give everyone a brief introduction, let's take a look together!
I. Causes of Fertilizer Burn
1. Applying undecomposed farmyard manure
When fertilizing eggplants, farmyard manure is a very good fertilizer. But many farmers, when applying farmyard manure, do not fully decompose it, or mix it into the nutrient soil. And the farmyard manure will begin to ferment, producing a large amount of heat, thereby causing the seedlings to be scorched and resulting in fertilizer burn. After the seedlings are scorched, their color will gradually turn brown, the new roots will stop growing, causing the roots' fertilizer uptake to be blocked, affecting the growth of the entire plant.
2. Improper topdressing
When eggplants enter the peak fruiting stage, it is generally in summer and other high-temperature seasons. The topdressing work at this time requires our particular attention. If, when topdressing with chemical fertilizers such as ammonium bicarbonate, no attention is paid to the temperature, then the ammonia content in the air increases, causing ammonia poisoning in the plants. This causes the plants to develop water-soaked lesions, and then the color gradually turns brown. If too much fertilizer is applied, then it will cause a large number of leaves to dry up, a fertilizer burn phenomenon.
3. Improper spraying of foliar fertilizer
The application of foliar fertilizer is also very important for the growth of eggplants. But because many people do not understand foliar fertilizer well enough, they think that applying more foliar fertilizer is beneficial and harmless to the growth of eggplants. And some manufacturers, when producing foliar fertilizer, add a large amount of hormone substances that have a stimulating effect on crops. If too much is applied, then it will cause foliar fertilizer burn, causing the leaves to become stiff, deformed, the stems to become thick and sturdy, and various other adverse phenomena, causing trace element poisoning in the plants.
II. What to Do About Fertilizer Burn
When we apply organic fertilizer, we must ensure it is fully decomposed. When piling up organic fertilizer, microorganisms should be used to decompose and break it down into nutrients that eggplant plants can utilize. Only such organic fertilizer is suitable for eggplant absorption. If symptoms are found to occur, then water promptly, which can effectively alleviate them. Generally, after about a week, normal growth can be restored, but attention must also be paid to controlling the amount of watering, not watering excessively, to prevent waterlogging damage.
Then, when we topdress in summer and other high-temperature seasons, furrow application should be the main method, covering with soil after fertilizing. Fertilizer should not be applied at noon and other such time periods. If fertilizing in the evening, then it should be combined with ventilation and watering work. Then, when spraying foliar fertilizer, attention should be paid to controlling the dosage, and the foliar fertilizer should be mixed properly, and it also should not be done at noon. Generally, it is done after 3 p.m.
