First, the amount of fertilizer applied should not be too large .

If the amount of one-time fertilization is large during drought, it will be easily washed away when it encounters heavy rain after drought. This will not only cause economic losses to farmers but also pollute the environment. Linyi Fertilizer Network Copyright

Second, the deep application of fertilizer, water pressure fertilizer Linyi fertilizer network copyright

In the case of drought, the fertilizer is volatile if only the fertilizer is applied to the surface. If there is heavy rain after a drought, it is easy to be washed away by the rain. Therefore, the fertilizer should be applied as deep as possible, and the fertilizer should be added after the application to maintain the fertilizer efficiency.  临沂肥网 Copyright

Third, pay attention to the reasonable mix of fertilizers, especially potassium fertilizer, boron fertilizer

Many studies have shown that suitable potassium can increase root-shoot ratio and enhance crop water absorption capacity; and under drought conditions, suitable potassium can also promote the accumulation of proline and regulate cytoplasmic swell pressure to enhance crop drought resistance. In addition, drought is easy to induce boron deficiency in crops, especially peanuts, fruit trees, rapeseed, etc. that are growing. Therefore, under drought conditions, attention should be paid to the appropriate application of potassium and boron fertilizers. Linyi Fertilizer Network Copyright
