Improve urea fertilizer efficiency
Urea is a widely used fertilizer among farmers in our city, especially during the summer when it's ideal for top-dressing vegetables and crops. But how can we make the most of urea application? Recently, a reporter from Quanzhou City Bureau of Agriculture shared some useful tips that could help improve its effectiveness.
First, it's important to determine the right amount of urea based on soil fertility. On highly fertile soils, applying 20 kg per acre is sufficient. For moderately fertile land, 23 kg per mu is recommended, while on low-yielding soils, up to 27 kg per mu may be needed. This ensures you're not over or under-fertilizing, which can affect crop yield and quality.
Another key tip is to do a deep cover after applying urea. When urea is left on the surface for 4–5 days at room temperature, a significant portion of the nitrogen can be lost through volatilization, especially in calcareous or alkaline soils. This reduces the efficiency of the fertilizer, with only about 30% being absorbed by the plants. To avoid this, it's better to incorporate urea into the soil by digging a shallow pit or working it into the ground at least 10 cm deep, especially when applying it to upland crops.
Also, keep a safe distance between the urea and the plant roots. Urea has a high nitrogen content and is very hygroscopic, meaning it can absorb moisture from the air and potentially burn young plants if applied too close. It’s crucial to avoid placing urea directly near the base of the plants or dropping it into the center of the crop, as this can damage the seedlings and hinder their growth.
Finally, don’t water immediately after top-dressing. Urea needs time to convert into a form that plants can absorb. If you water too soon, it can wash away the fertilizer, leading to significant losses. It’s best to wait 3–5 days before applying light irrigation, allowing the urea to properly integrate into the soil.
By following these simple yet effective methods, farmers can maximize the benefits of urea and ensure healthier, more productive crops.
