摘要

介绍了使用两种技术选择获得的鸟粪石作为控释氮磷肥样品的营养成分定量分析结果。研究表明，使用传统的鸟粪石沉积技术会形成粗粒产品（平均晶粒尺寸578μm）。研究证实，与传统技术相比，改进的技术可以获得高度分散的鸟粪石（平均晶体尺寸19μm），颗粒表面更宽，铵含量为理论值的98–99%，养分释放率更高。研究发现，采用改良工艺合成的Struite作为控释MgNP肥料具有更好的性能。

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

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.

期刊介绍： The Journal "Ekologia i promyshlennost Rossii" («Ecology and Industry of Russia») is aimed to promote acquaintance of the world scientific and technical public and specialists, interested in the problems of the environment protection, with advanced achievements of the science and engineering practice on securing of stable (self-supporting) evolution within the limits of the United Nations accepted recommendations (RIO 92 and RIO+20). A circle of papers includes basic researches and engineering decisions, analytical and methodical operations, reviews on journal subjects. The journal lays special emphasis on methodical elaborations, analytical investigations in the sphere of creating the ecological culture of the population, to the features of ecological education in higher schools of the country for the sake of actualization in specialists'' consciousness of the scientific necessity to know environmental problems of the modern civilization and paths of their settlement. Original papers and investigations of scientists and specialists on separate themes occupy an independent niche of issues under the «Cover story» heading. The journal task is to promote practical implementation of scientific and engineering decisions in the field of decrease of anthropogenic load on the biosphere and environment protection (open lectures, round tables, discussions and so forth). Ecology and Industry of Russia is an informational reference book about the newest developments of the Russian and foreign scientists and the companies realized in Russia, the CIS and Baltic countries, and far-abroad countries. The journal publishes information reports about holding in Russia and abroad the international, all-Russian and regional congresses, conferences, and symposiums related to the journal subjects.
