Summary: Inoculation with phosphate-solubilizing bacteria and the application of different phosphorus sources can enhance soil P availability, improving the productivity of Kikuyu grass. This study found that inoculation with a PSB consortium and fertilization with rock phosphate increased soil labile P and improved grass yield and quality. These findings highlight the importance of PSB inoculation for sustainable agricultural systems.

Summary: The study found that coating phosphorus fertilizers with polymer or complexing them with humic acid does not increase phosphorus availability or diffusivity in soil, as these processes are mainly driven by soil characteristics. Therefore, the potential of these controlled-release phosphorus fertilizers in increasing phosphorus use efficiency is low.

Summary: Controlled release phosphorus fertilizers combined with humic acid have a greater impact on maize yield and PUE compared to conventional fertilizers. Factors such as soil P content, photosynthesis, and hormone levels play a key role in maize growth. The combination of coated diammonium phosphate and humic acid improve soil nutrient supply and enhance photosynthetic capabilities, ultimately increasing yield and PUE.

Summary: The experiments focused on calcination and digestion to increase the grade of phosphate rock, investigating the release of fluorine and chlorine in the process. Fluorine and chlorine mainly existed in carbonate-bound and residual forms in phosphate rock. Optimal digestion conditions were found to be a liquid-solid ratio of 2.5:1, digestion temperature of 60 degrees C, and digestion time of 50 minutes.

Summary: The study compared the P use efficiency (PUE) of four different P sources with organic amendments in maize crop under calcareous soils, showing that phosphorus application significantly improved maize growth, yield, P uptake and PUE, especially when pretreated with organic amendments. The results suggest that pretreatment of P sources with organic amendments is an economical and feasible approach to improve maize yield and PUE, with on-farm acidulation of RP as a recommended strategy for P management in maize in alkaline calcareous soils.

Summary: The aim of this study was to evaluate the effects of silicon fertilization on phosphorus fertilizer use efficiency in acidic tropical soil, and to investigate the potential of using glacial rock flour as a source of silicon. The results showed that glacial rock flour can rejuvenate strongly weathered agricultural soils, improve stress tolerance in plants and ultimately increase yields, but it does not improve phosphorus availability in acidic soils.

Summary: This research aimed to investigate the dissolution changes of two Moroccan sedimentary phosphate rocks (PRs) under different rates of phosphogypsum (PG) addition, and evaluate their effects on acidic soils. The results showed that the addition of phosphogypsum can increase the available phosphorus content in the soil, but has no significant effect on the dissolution rate of phosphate rocks. These findings are of great significance for phosphate application in acidic soils.

Summary: The continuous application of phosphate mineral to soil leads to the addition of apatite during each crop growing season, which is a significant concern for sustainable agriculture. This study identified and characterized efficient phosphate solubilizing microbes from hydroxyapatite mines to solubilize apatite in the soil. Results showed that the isolated bacterial and fungal strains, particularly when combined with compost, increased plant phosphorus uptake and soil phosphorus content. This highlights the potential of efficient P solubilizers for sustainable agriculture by utilizing indigenous phosphate reserves of soil in combination with organic amendments.

Summary: An in vitro synthetic enzymatic biosystem was designed and constructed for the thermodynamics-driven production of D-allulose from low-cost starch, achieving high product yields. This strategy could significantly reduce the production cost of D-allulose and provide a promising alternative for the cost-efficient production of other rare sugars on an industrial scale.
