“…17 Matrices are strategic for getting around the particle size problem, as they can be processed as granules while, simultaneously, keeping small P particles from agglomerating. 18 At the same time, the matrix acts as a barrier, preventing a fast P delivery. 19 The studied polysulfide is an especially interesting material as it can provide sulfur to plants, an important macronutrient for plant growth that is frequently unavailable in agricultural soils.…”

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 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 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. Additionally, St/PS achieved a 22% sulfur use efficiency against only 8% from TSP/AS. Root system architectural changes may explain these results, with higher proliferation of second order lateral roots in response to struvite ongoing P delivery. Overall, the composites showed great potential as efficient controlled-release fertilizers for enhanced soybean productivity.

“…The biological factors are bacteria, fungi and other microorganisms that biodegrade the coating based on a biodegradable or synthetic polymeric material, thus allowing the release of nutrients and its fixation into the soil. The chemicaltriggered mechanisms are moisture, solubilization, pH variation, soil type (Weeks and Hettiarachchi, 2019;Ramzan et al, 2020), and ion exchange reactions (Ribeiro and Carmo, 2019). The physical factors are ultrasound, magnetic field, heat and diffusion-controlled release (Mikkelsen, 2018;Ribeiro and Carmo, 2019).…”

Nitrogen (N) is the most critical element limiting agricultural production at a global scale. Despite many efforts, the N use efficiency (NUE) in agriculture remains in a range of less than 50%. Reaching targeted crop yields has resulted in N overuse, which is an economic and environmental concern worldwide. The continuous exploration of innovative solutions has led to the synthesis of novel nanomaterials, resulting in a powerful tool for the development of new technological products. Nanofertilizers are one of the most promising engineered materials that are being tested, either for soil or foliar applications. Encouraging results have been obtained using nanofertilizers in different plant species, however, limited information has been reported about its use in grasslands. Commonly, N is applied to grassland soils as granular fertilizers, which may result in significant losses via surface runoff or leaching, ammonia (NH3) volatilization and N oxides (N2O, NO, NOx) emissions. Nitrogen nanofertilizers are expected to increase NUE by improving the effectiveness of N delivery to plants and reducing N losses to the environment. Information on the efficiency of the use of N nanofertilizers in grasslands species is scarce and the application strategies that can be used to avoid N losses are poorly understood. New scenarios of increasing economic and environmental constraints may represent an opportunity for N nanofertilizers application in grasslands. This article reviews its potential use as an innovative approach to improve NUE and reduce N losses to the wider environment, analyzing potential shortcomings and future considerations for animal food chains.

“…Recently, our research group accomplished both of these criteria with the development of fertilizer composites based on a polysulfide matrix containing dispersed ground struvite ( Valle et al, 2021 ). Matrices are strategic for getting around the particle size problem, as they can be processed as granules, while simultaneously keeping small P particles from agglomerating ( Ribeiro and Carmo, 2019 ). At the same time, the matrix acts as a barrier, preventing a fast P delivery ( Mann et al, 2019 ).…”
