Triple Superphophate（TSP）

Double superphosphate, also called three-material superphosphate, is a highly concentrated phosphate fertilizer. It is a water-soluble phosphate fertilizer, ie the phosphorus contained in the fertilizer is easily water-soluble and can be directly absorbed and used by plants.

The effective method of application of  superphosphate is the same as that of ordinary calcium phosphate and can be used as a base fertilizer or top dressing.

Packaging: Usually packed in a plastic bag lined or woven with a 25kg plastic bag, or customized as required.

Q1: Are you a trading company or a manufacturer?

A: We are a manufacturing company. Located in Shanxi, China.

Q2: How is superphosphate applied as a base fertilizer?

A: When superphosphate is used as the base fertilizer, the rate of application per mu for the soil with no available phosphorus can be around 50 kg per mu, and half of it is evenly distributed in front of the cultivated land, combined with the cultivated land as the base fertilizer. Before sowing, evenly sprinkle the other half, combine it with the soil preparation and apply it flat into the soil for a multi-layer application of phosphorus. In this way, the fertilizing effect of superphosphate is better and the utilization rate of its active ingredients is also high. If it is mixed with organic fertilizer as a basic fertilizer, the application rate of superphosphate per mu should be about 20-25 kg.

Q3: Do you supply samples?

A: We can provide you samples of no more than one kilogram, but you need to pay for the freight.
