Polymer Coated Slow Release Fertilizer

Polymer coated slow release fertilizer is a new type of controlled release nitrogen fertilizer, which is developed by us for many years and has a national patent technology. Using advanced membrane coating technology urea granules are coated with polymer which controls the release as required thereby increasing nitrogen utilization rate. The release rate of polymer coated urea is consistent with the rate of nutrient uptake by crops, which improves the efficiency of fertilizer utilization. It is suitable for various of soil and crops, and wins an excellent reputation among our partners all over the world due to high performance.

● Smooth surface and uniform particle size is conducive to the mechanization of fertilization.

APPLICATION :

Fertilization method:

1. Polymer coated urea (PCU) as a base fertilizer can be applied alone, but with other base fertilizers (including available N, P, K), the effect is better.The application rate of PCU is about 300 to 750kg/ha, depending on the amount of nitrogen applied to other base fertilizers.

2. PCU can be applied as side bands or holes in soil to depths of 10 to 15 cm. Seeds and fertilizers should be separated when applied simultaneously. In dry areas, irrigation is needed to release nitrogen and promote crop growth. Although topdressing nitrogen fertilizer can meet the growth needs of the whole growth period, it still has certain benefits.

Storage:

Polymer coated fertilizer should keep in a cool, well-ventilated area.Keep away from water sources such as ponds, pools etc. Keep out of reach of children.

Harmful if swallowed - Do not inhale.
