Struvite Got by a Modified Technology as the Basis of an Environmentally Friendly Controlled-release MgNP-fertilizer

Abstract
The results of a quantitative analysis of nutrients based on samples of struvite as a controlled release nitrogen-phosphorus fertilizer, obtained using two technology options, were presented. It was shown that the use of traditional struvite deposition technology leads to the formation of a coarse-grained product (average crystal size 578 μm). It was confirmed that the modified technology allows to obtain highly dispersed struvite (average crystal size 19 μm) with a more extended particle surface and an ammonium content of 98–99% of the theoretical value with a higher nutrient release rates compared to struvite got by conventional technology. Struvite synthesized by the modified technology was found to show improved performance as a controlled release MgNP fertilizer.
