Unreasonable Fertilization Methods? Avoid These Four Common Mistakes

Shallow Fertilization

Fertilizer is prone to volatilization and loss, or struggles to reach the crop roots, which is not conducive to crop absorption and results in low fertilizer use efficiency. Fertilizer should be applied 16-26 cm to the side and below the seeds or plants.

Improper Application of Chemical Fertilizer to Crops

It may cause fertilizer damage, with phenomena such as seedling burn and plant wilting. When nitrogen fertilizer is applied excessively, there is a large amount of ammonia or ammonium ions in the soil. On one hand, ammonia volatilizes and, upon meeting fog droplets in the air, forms alkaline droplets that burn the crops, producing scorched spots on the leaves; on the other hand, ammonium ions undergo nitrification in dry soil and, under the action of nitrosifying bacteria, are converted into ammonium nitrite, which gasifies to produce nitrogen dioxide gas that poisons the crops, causing irregular water-soaked spots on the crop leaves, with the areas between the veins gradually turning white.

Excessive Use of a Certain Nutrient Fertilizer

It will not only poison the crops, but also hinder the crops' absorption of other nutrient elements, causing deficiency symptoms.

Applying Fresh Human Excrement and Urine Directly to Vegetables

Fresh human excrement and urine contain large amounts of pathogens, toxins and parasite eggs. If applied directly without being decomposed, it will contaminate vegetables and easily spread diseases. It can only be applied after high-temperature composting and fermentation or harmless treatment.
