Urea is a kind of fertilizer that farmers in our city prefer to use. Especially in the summer, vegetables, crops, etc. are suitable for top dressing with urea. So, how can we increase the effect of urea dressing? A few days ago, the reporter learned about several tricks from Quanzhou City Bureau of Agriculture.
Determine the amount of top dressing based on soil fertility. On high-fertility soils, topdressing 20 kg per acre; on moderately fertile soil, topdressing 23 kg per mu; on low-yielding soils, top-dressing 27 kg.
Do a deep cover. When urea is applied on the ground surface for 4 to 5 days at room temperature, most of the nitrogen will be volatilized by ammoniating. Its utilization rate is only about 30%, especially on the surface of calcareous and alkaline soils. Seriously. Therefore, when topdressing upland crops with urea, it is better to grind the pit or deeper than 10 cm.
Keep crops at a certain distance. Due to the high nitrogen content of urea and the high concentration of nutrients, it has great hygroscopicity. Therefore, when topdressing, it is necessary to prevent urea from being applied near the roots of crops, and it is even more important not to drop urea into the heart of the crop so as not to burn the seedlings and affect the growth. Therefore, it must be kept at a certain distance from the crop.
Do not apply water immediately after topdressing. After urea is applied to the soil, it cannot be absorbed by the soil before it is converted and transformed. If you apply water immediately after topdressing, it will cause a large loss of urea. Generally, it is advisable to fill the small water 3 to 5 days after topdressing.
