I. How long does it take for water-soluble fertilizer to take effect after application
Water-soluble fertilizer is a fast-acting fertilizer, and the effect can be seen within a short time after fertilization. Generally, the specific effective time is based on The formula material of water-soluble fertilizer is related:
After applying water-soluble fertilizer, because crop absorption is a dynamic process, it takes a certain time, so it is not effective immediately, and ordinary water-soluble fertilizer generally waits 5-7 days after application You can see the effect; however, there are also some water-soluble fertilizers on the market that have a particularly fast effect, which can be effective in a day or two. These are generally added with hormones such as sodium naphthalene acetate and potassium indole. Although the effect is fast, the fertilizer effect is also Short, long-term use will also cause premature senescence of crops, flower and fruit drop, etc., it is not recommended to use it frequently.
Second, is it effective to rain three hours after the water-soluble fertilizer is applied?
No.
Water-soluble fertilizer is generally fertilized before or after rain. It should not rain within a day before and after fertilization, so that the fertilizer effect can be exerted. If it rains three hours after the application of water-soluble fertilizer, the fertilizer effect will be diluted, Loss; generally, it rains soon after fertilization with water-soluble fertilizer. After the rain stops, a small amount of water-soluble fertilizer should be added when the soil is semi-dry.
3. How long does the water-soluble fertilizer last for fertilizer use
Generally speaking, the duration of water-soluble fertilizer as a top dressing is about 15-20 days.
Because the water-soluble fertilizer is instant and quick-acting, it can be dissolved into water and applied directly to the soil before use, which can be directly absorbed and utilized by the crop root system, and can quickly supplement the required nutrients for crops during the peak fertilizer demand period. Due to this feature of water-soluble fertilizer, it can take effect quickly after use, and the duration is generally 15-20 days, and the fertilizer period is generally 7-15 days in winter and high temperature weather.
