The correct method for broadcasting compound fertilizer during the rice stem elongation stage
During the rice stem elongation stage, topdressing is generally carried out 1 to 2 times. In previous years we used urea, but this year we switched to a high-tower granulated fertilizer. This is a compound fertilizer with high nitrogen and low phosphorus and potassium. The fertilizer granules are round and smooth on the outside, with holes inside, and have a relatively low specific gravity. Before fertilizing, we first drained the flooded water, then broadcast the compound fertilizer granules on the soil surface, and immediately let water back into the field. After the water layer was full, we found that some fertilizer granules appeared on the water surface. These floating granules were blown to one side by the wind, and some stayed in the sheltered corners.
