Product description

Struvite is a potentially marketable product for the P fertilizer industry. Its genuine slow release property can be more efficiently used by crops, because it meets nutritional demands of crops in a better way and prevents the burning of plant roots, even when applied in excess quantities, guarantees a slow but steady nutrient supply. Moreover, struvite is an effective water-soluble phosphorus fertilizer in neutral and slightly acidic soils.

The amount of phosphorus and magnesium that the struvite could provide is higher than typical fertilizers (12% P and 9% Mg). However, the amount of nitrogen is lower than typical fertilizers (around 5 %N) and the percentage of potassium is very low so it is recommended to apply combined with conventional fertilizers to satisfy N and K demand. It can be easily combined with other solid fertilizers or dissolved in a slightly acidic solution.

Cd has not been detected and the amount of organic matter is very low, TOC (total organic carbon) is lower than 0.8%, thus it is a secure environmental friendly product.
