Ensuring the steady increase of the comprehensive agricultural productivity and guaranteeing the quality and safety of crops have become a point of high concern for all sectors of society. Then, the first to be affected are naturally the farmers. To ensure their profits, they not only need to put effort into the selection of seedlings, but also cannot neglect the application of fertilizers. Today, we will introduce when is the best time to apply foliar fertilizer.
When is the best time to apply foliar fertilizer?
First of all, it is necessary to know what foliar fertilizer is. Foliar fertilizers are those that take foliar absorption as the main pathway and directly apply the required nutrients to the leaves. Rapid fertilizer effect and high fertilizer utilization rate are its characteristics, but the nutrients sprayed are easily washed away by rainwater; The application of foliar fertilizers should be timed properly to address issues such as rapid drying of the foliar surface by the spray solution. The following takes the high-yield and quality-improving foliar fertilizer as an example:
1. Foliar spraying is generally carried out on days without wind or direct sunlight. Generally speaking, the evaporation of plants is small before 9 a.m., which is suitable for foliar spraying. After 4 p.m., it is also a good time. At this time, the intensity of light will gradually weaken over time, which can reduce the evaporation of fertilizer solution and prolong the retention time of the fertilizer solution on the leaves, allowing the crop leaves to fully absorb nutrients.
2. in case of sudden precipitation, such as rain after fertilizer application, the fertilizer solution on the leaves will be washed away or its concentration will be significantly reduced. Generally speaking, a re-application is required. However, the high-yield and quality-improving foliar fertilizer adopts the chelating energy technology from Israel. The chelating energy process is safer and easier to absorb. There is no need to re-apply after ten minutes of rain, which is very convenient for farmers.
3. during the process of leaf selection, it is recommended that everyone choose reliable brand products, which are reassuring to use and will not waste time or cost. The efficacy fertilizer is developed based on the "efficacy" required by the growers, meeting their needs and has been widely recognized by the growers.
After the above introduction, everyone should have some understanding of when to apply foliar fertilizer for the best effect. I hope it will be helpful to all of you. At the same time, remember to choose a regular foliar fertilizer brand and never be tempted by small bargains.
