Struvite is considered as promising P fertilizer compared to mineral commercial phosphorus fertilizers which may in future replace phosphate fertilisers in the face of dwindling phosphate resources. Its fertilising value is due not only to its significant phosphorus content, but also to its magnesium and nitrogen content, and the slow release of the components.  We proposed the application of Crystal Green in examining the response of soybean cultivar Abaca to struvite fertilization in terms of yield, chlorophyll content and soil microbiological changes. A pot experiment was set up at the Pawłowice Research and Education Station on soil with low phosphorus abundance with two variable factors: differential placement of phosphorus fertilizer (band and broadcast) and phosphorus fertilisers (superphosphate and struvite). The method of phosphorus placement had a significant effect on biometric traits, chlorophyll a content and microbial activity. Struvite fertilization caused significant changes in chlorophyll and carotenoid contents. Significantly higher contents of chlorophyll a and carotenoids were noted under struvite fertilization as well as total chlorophyll. Fertilizer placement caused a significant effect on chlorophyll a content placed band. Both the methods of application and the type of phosphorus fertilizer had a significant effect on microbiological activity at the two measurement dates. Total glomalins content was significantly higher only in the case of band application of phosphate fertilizers at the end of the experiment, and the dehydrogenase activity was significantly increased, with this method of fertilizer application, at the flowering time of soybean. Despite the lack of significant differences in the studied elements of yield structure, their values in many cases were comparable and even slightly higher; hence, a fertilizer that aligns with the assumptions of the circular economy is worth attention and further study in field conditions. However, long-term studies are needed to test the cultivation of plants under field conditions and their reaction to struvite as well as their effect on the content of phosphatases, which stimulate the conversion of organic phosphorus compounds into inorganic phosphates directly available to plants and soil organisms.
