Why Use of Nitrogen Fertilizer as the Top Dressing Improves the Utilization Rate

At present, the existing nitrogen fertilizers are water-soluble. If nitrogen fertilizer is used for the whole growth period as a base fertilizer before application, the residence time of nitrogen fertilizers in the soil is very long, and the early growth of the crops is slow, the absorption is low, and it is easy to cause Nitrogen fertilizer loss. When the high temperature and rainy season arrives, the crop enters a rapid growth stage and requires a lot of nutrients. At this time, some nitrogen fertilizers already applied to the soil have already been lost, and the nutrient supply is insufficient, which will cause the post-crop growth and deferment and reduce the yield. The demand for nutrients during the growing period of crops has a phased characteristic. Seedling period is the critical period of nutrition. The amount of nutrients needed is not large, but it is very important. It is generally supplied through seed fertilizers. In summer, it is the rapid growth period of crops and also the maximum efficiency period of crop nutrients. At this time, topdressing, the efficiency of absorption and utilization of nutrients by crops is high. Therefore, the utilization rate of fertilizers is also significantly increased. However, it should be noted that topdressing N and K fertilizers should be covered with soil to avoid the loss of nitrogen during the high temperature and rainy season.
