What is the effective period of the complexing slow release urea fertilizer in days.

The effective period of slow-release urea fertilizer is usually between 90 and 120 days. 

Compared with ordinary urea, slow-release urea has the advantages of longer usage time, less fertilizer application, and less environmental pollution. The reason for its longer fertilizer effect period is that slow-release urea can slowly release nitrogen elements through special technology treatment, providing long-lasting nutrition for crops. ‌

The factors that affect the effective period of slow-release urea fertilizer include temperature, moisture, soil microorganisms, and plant absorption capacity. High temperature will accelerate the release rate of nitrogen element, while low temperature will slow down the release rate. The moisture content in the soil has a significant impact on the release rate of slow-release urea. When there is sufficient moisture, nitrogen is more easily dissolved and infiltrated into the deep soil layers for crop absorption and utilization. In addition, the activity of soil microorganisms can also affect the decomposition and transformation process of slow-release urea, and abundant microorganisms may accelerate its decomposition.

In order to fully utilize the fertilizer efficiency of slow-release urea, farmers should adjust the application time and amount reasonably according to the local climate, soil conditions, and crop growth status. It is generally recommended to use slow-release urea as a base fertilizer to fully utilize its slow release characteristics. If it needs to be used as topdressing, attention should be paid to using it in combination with ordinary urea to meet the needs of crops at different growth stages.
