Single Super Phosphate in Phosphate Fertilizers

Short Description:

Single Super Phosphate(SSP), is the most popular phosphatic fertilizer after DAP as it contains 3 major plant nutrients namely Phosphorus, Sulphur and Calcium along with traces of many micro-nutrients. SSP is indigenously available and supply can be made at short notice. SSP is an excellent source of three plant nutrients. The P component reacts in soil similarly to other soluble fertilizers. The presence of both P and sulfur(S) in SSP can be an agronomic advantage where both of these nutrie...

    Product Description

    Single Super Phosphate(SSP), is the most popular phosphatic fertilizer after DAP as it contains 3 major plant nutrients namely Phosphorus, Sulphur and Calcium along with traces of many micro-nutrients. SSP is indigenously available and supply can be made at short notice. SSP is an excellent source of three plant nutrients. The P component reacts in soil similarly to other soluble fertilizers. The presence of both P and sulfur(S) in SSP can be an agronomic advantage where both of these nutrients are deficient. In agronomic studies where SSP is demonstrated to be superior to other P fertilizers, it is usually due to the S and/or Ca that it contains. When locally available, SSP has found wide-spread use for fertilizing pastures where both P and S are needed. As a source of P alone, SSP often costs more than other more concentrated fertilizers, therefore it has declined in popularity.

    Single Superphosphate(SSP) was the first commercial mineral fertilizer and it led to the development of the modern plant nutrient industry. This material was once the most commonly used fertilizer, but other phosphorus(P) fertilizers have largely replaced SSP because of its relatively low P content.

    Phosphate Introduction

    Phosphate is one of the main downstream demand products of phosphoric acid, accounting for more than 30%. It is one of the natural components of almost all foods. As an important food ingredient and functional additive, phosphate is widely used in food processing. China is rich in phosphate and phosphate products with large production scale. There are about 100 varieties and specifications of phosphate and phosphide products, and Zongsheng has a production capacity of nearly 10 million tons. The main products are phosphoric acid, sodium tripolyphosphate, sodium hexametaphosphate, feed phosphate, phosphorus trichloride, phosphorus oxychloride, etc.

    At present, the demand for traditional bottom phosphate products in China is weak. Traditional phosphate such as sodium tripolyphosphate will cause the problem of "eutrophication" in the water area, the content of sodium tripolyphosphate in washing powder will gradually decline, and some enterprises will gradually replace sodium tripolyphosphate with other products, reducing the demand of downstream industries. On the other hand, the demand for fine and special phosphorus chemical products such as medium and high-grade phosphoric acid and phosphate (electronic grade and food grade), compound phosphate and organic phosphate has increased rapidly.
