Superphosphate ammoniated granular NP 3:16 is a basic water-soluble phosphate fertilizer that is obtained during saturation of superphosphate with anhydrous ammonia, ammonia solution or ammonia. Its composition depends on the amount of introduced ammonia.

Superphosphate ammoniated has good physical properties. The composition includes phosphorus (P2O5) – 13 ± 1% and nitrogen (N) 1.0 ± 0.5%.

This fertilizer is used for the main application – before sowing, simultaneously with sowing and as a fertilizer for all plant cultures at all types of soils. Superphosphate is particularly effective in alkaline and neutral soils. Granular superphosphate, unlike powdered, doesn’t cake and stick together.

Superphosphate ammoniated granular as a valuable component for the preparation of fertilizer blends, doesn’t acidify the soil. It’s applied on all types of soils, for all crops and in a variety of ways. Nitrogen of ammoniated phosphate is well absorbed by plants. Therefore, when introducing this fertilizer, it’s necessary to take into account the nitrogen content and to change the norms of nitrogen fertilizers accordingly.
