Summary: Phosphorous-containing heterocycles exhibit markedly different properties than common heterocyclic compounds, but the lack of synthetic methods has made the study of these molecules difficult, especially in terms of constructing P-stereogenic centers. This research presents a simple, versatile method for synthesizing PN-heterocycles with P(V) centers from phosphanamines through palladium catalyzed intramolecular C-P coupling.

Summary: This study investigates the effects of agricultural management on organic phosphorus (Po) and the Po/phosphate ratio in agricultural soils and adjacent ditchwater. The results show that Po content and Po/phosphate ratio are significantly higher in manure-amended pasture compared to fertilizer-applied cropland. Water quality data also indicate higher flux of dissolved non-reactive P and Po/phosphate ratio near the pasture.

Summary: This study aimed to quantify the losses of water, sediments, and phosphorus fractions in different textured soils due to surface runoff under varying terrain slopes and phosphorus application rates. Results showed that Nitisol soil experienced higher losses compared to Cambisol soil, attributed to factors such as higher rainfall volume, rate of transported material, lower water infiltration, and accumulation of phosphorus in the surface layer.

Summary: This study investigated the impact of irrigation water quality on phosphorus (P) dynamics and leaching from saline-sodic soil during reclamation using gypsum alone or in combination with organic materials. The results showed that adding organic materials with gypsum increased the concentration of water-extractable P and reduced P leaching. The properties of the leachate, such as CO32-, HCO3-, pH, and SO(4)(2-)content, were found to be closely related to P leaching.

Summary: The effect of long-term soil phosphorus on in situ nitrous oxide emissions from temperate grassland soil ecosystems is investigated in this study. It is found that low soil phosphorus significantly increases nitrous oxide emissions, inhibits nitrogen uptake, and affects the response to nitrogen fertilizers. Optimizing soil phosphorus levels can reduce nitrous oxide emissions and improve nitrogen use efficiency.

Summary: The stereoselective synthesis of molecules bearing stereogenic phosphorus (V) centers is a challenging task in organic chemistry. Existing methods rely on diastereocontrol using chiral auxiliaries, while catalytic, enantioselective methods offer an alternative approach.

Summary: The continuous application of organic fertilizers can lead to the accumulation of organic phosphorus in soil, with LMWOP compounds mineralizing faster in P-rich soil. Sorption to the solid phase may slightly repress the mineralization of LMWOP compounds in the short term.

Summary: This study evaluated the impacts of phosphorus fertilizer sources and rates on maize growth and the bioavailability of cadmium. The results showed that MAP and DAP had positive effects on plant growth and yield characteristics of maize in different soil textures. The accumulation and uptake of cadmium in soil were also significantly influenced by phosphorus sources, levels, and soil texture. Therefore, the type of phosphorus fertilizer should be chosen based on soil texture and the human consumption of the crop to avoid cadmium toxicity.

Summary: Phosphorus is critical for plant growth, but natural sources are limited, necessitating improved phosphorus recycling. The addition of bone char plus enhances solubilization potential, while low phosphorus concentrations in control plots and slow release from bone char favor phosphorus recycling from biomass.

Summary: The variability in phosphorus sorption and desorption among different soil types is not reflected in current agronomic guidance for sustainable phosphorus use. A framework integrating soil phosphorus sorption dynamics with soil test P is proposed to improve fertilizer decision-making. Predicted values from MIR spectroscopy or pedotransfer functions can be used for classifying soils into phosphorus management categories, with pedotransfer functions offering greater reliability but MIR spectroscopy being faster and less resource intensive.

Summary: This study found that soil texture, carbonates content, water retention capacity, and organic matter substantially affected phosphorus fractions in calcareous soils. Biological mineralization processes played a key role in the soil phosphorus cycle, while total phosphorus, carbonates content, soil texture, and water availability drove forest productivity in the studied plots.

Summary: The study aims to investigate the effects of altered nutrient availability on phosphorus fluxes in forest soils and examine the variations in response at sites with different phosphorus statuses. The results show that phosphorus fluxes are highly variable and the response to nitrogen and phosphorus addition differs between sites. Therefore, the factors determining phosphorus translocation in forest soils under altered nutrient availability are the spatio-temporal patterns of preferential flow pathways in soil columns and the phosphorus nutrition strategy of the ecosystem.

Summary: This study investigated the desorption and solubilization mechanisms of legacy phosphorus in agricultural soils. The results showed that sulfate has a stronger competition for phosphorus desorption, and agricultural soils in the coastal areas are threatened by sea level rise and inundation.

Summary: In this study, tert-Butyl-substituted diphospha[2]ferrocenophane was utilized as a stereochemically confined diphosphane to investigate the addition of various dichalcoganes. Bischalcogenophosphinous acid esters with four soft donor sides were obtained and characterized, and the coordination chemistry of multidentate ligand 3b towards d(10) coinage metal centers was explored, resulting in various bimetallic complexes.
