abstract = {In face of the alarming world population growth predictions
and its threat to food security, the development of
sustainable fertilizer alternatives is urgent. Moreover,
fertilizer performance should be assessed not only in terms
of yield but also in root system development, as it impacts
soil fertility and crop productivity. Fertilizers containing
a polysulfide matrix (PS) with dispersed struvite (St) were
studied for S and P nutrition due to their
controlled-release behavior. Soybean cultivation in a closed
system with St/PS composites provided superior biomass
compared to a reference of triple superphosphate (TSP) with
ammonium sulfate (AS), with up to 3 and 10 times higher mass
of shoots and roots, respectively. Root system architectural
changes may explain these results, with a higher
proliferation of second order lateral roots in response to
struvite ongoing P delivery. The total root length was
between 1,942 and 4,291 cm for plants under St/PS composites
and only 982 cm with TSP/AS. While phosphorus uptake
efficiency was similar in all fertilized treatments
$(11–14\%),$ St/PS achieved a $22\%$ sulfur uptake
efficiency against only $8\%$ from TSP/AS. Overall, the
composites showed great potential as efficient slow-release
fertilizers for enhanced soybean productivity.},
