What are the effects of macronutrient water-soluble fertilizers?

Macronutrient water-soluble fertilizers have the effects of promoting growth and activation, promoting roots and strengthening seedlings, preserving fruit and promoting swelling, detoxifying and preventing senescence, biologically resisting continuous cropping obstacles, and resisting disease while preserving fertilizer. According to the fertilizer requirements and characteristics of different crops, the corresponding fertilizers have different formulas. Those sold on the market include special water-soluble fertilizers for various crops such as vegetables, fruit trees, flowers, grain, cotton, and oil crops.

How are macronutrient water-soluble fertilizers used?

1. Avoid directly applying by flushing; use the secondary dilution method. Because water-soluble fertilizers differ from general compound fertilizers, they cannot be applied by conventional fertilization methods, which causes uneven fertilization and leads to phenomena such as burning seedlings and damaging roots, and small and weak seedlings. Secondary dilution ensures uniform flushing fertilization and improves fertilizer utilization efficiency.

2. Strictly control the amount of fertilizer applied. Water-soluble fertilizers have a higher nutrient content than general compound fertilizers, so the amount used is relatively smaller. Because of their strong quick-acting properties, they are difficult to retain in the soil for a long time, so the amount of fertilizer applied must be strictly controlled to avoid fertilizer loss, which reduces the economic benefits of fertilization and fails to achieve the goals of high yield, high quality, and high efficiency.

3. Use alone as much as possible or mix with non-alkaline pesticides. For example, when vegetables show nutrient deficiency symptoms or poor root growth, many farmers often use spraying water-soluble fertilizer to alleviate them. Water-soluble fertilizers should be applied alone as much as possible or mixed with non-alkaline pesticides, so as to avoid metal ions reacting and producing precipitates, causing fertilizer damage or pesticide damage to leaves.

The above is a relevant introduction to the effects of macronutrient water-soluble fertilizers. I hope it is helpful to everyone.
