Summary: Soil phosphorus is crucial for crop health and growth, and soil management practices, including fertilizer application and tillage, significantly impact soil phosphorus dynamics. The use of organic fertilizers is associated with an increase in soil Olsen-P content, while the no-till method results in an increase in organic phosphorus. Furthermore, soil texture and depth also play a role in the variation of phosphorus species in soil.

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: Phosphorus is the second most important nutrient for grass growth, but irrational use of chemical fertilizers leads to environmental degradation. In Ireland, soil testing is recommended for efficient nutrient management. This study finds that soil testing can reduce the use of chemical fertilizers, and is related to landscape characteristics and farm intensity, highlighting the need for targeted management approaches.

Summary: The analysis compared mineral concentrations in cow diets with recommendations, showing that phosphorus was fed closest to requirements, but other minerals were often overfed. Precision feeding for phosphorus is important for dairy production sustainability, but efforts should be made to limit overfeeding of trace minerals for environmental resiliency.

Summary: Phosphorus (P) fertilizer recommendations vary among countries, but the main principle is to maintain a target range of plant-available P in soil. However, the thresholds of target P fertility classes vary based on different soil test P methods, even among countries using the same method.

Summary: The utilization of residual soil phosphorus in agricultural soils is important for reducing phosphorus applications and pollution. The potential for using residual soil phosphorus varies among Canadian provinces, with the highest potential in the Atlantic provinces, Quebec, Ontario, and British Columbia.

Summary: Recycling phosphorus fertilizers from biogas digestates in agricultural production can help reduce resource consumption and promote environmental sustainability, which is crucial for future supply. Results show that these recycled phosphorus fertilizers have equivalent or even superior fertilizing properties compared to chemical synthetic fertilizers, and can be effectively applied in different soil conditions.

Summary: K fertilization is necessary for maximizing corn and cotton yields in soils with sub-optimum K availability, but maximizing yield doesn't always equal maximizing profit. Estimating the tradeoff between yield and fertilizer cost provides insights for producers.

Summary: Waterlilies have high demand for phosphorus supply, with plant growth and flowering improving with increasing phosphorus supply, while growth and flowering decline when potassium supply increases. Efficient nutrient uptake is essential, especially in soils with high phosphorus-sorbing capacity and low capacity for phosphorus acquisition by waterlily roots.

Summary: Straw return can improve soil phosphorus availability, reduce mineral phosphorus fertilization, and increase phosphorus apparent recovery efficiency for cotton production. However, it does not significantly affect seed cotton yield in a continuous barley-cotton rotation system on coastal saline soil.

Summary: The application of phosphorus fertilizers leads to the accumulation of uranium in agricultural soils, which is a persistent and global problem. However, the proportion of fertilizer-derived uranium in the soil has not significantly increased over the past 130 years.

Summary: Research showed that phosphorus fertilizer use efficiency in cereal crops is influenced by climate, soil, and management factors. The phosphorus content in aboveground biomass increased by 12.4% of the applied fertilizer, with lower PFUE in maize compared to rice and wheat, and lowest in soil with near neutral pH. There is great potential for improving PFUE in cereal crops.

Summary: Post-granulation acid treatment is an effective way to improve the availability of zinc in phosphatic fertilizers, reducing the precipitation of zinc phosphates and increasing the release rate and migration ability of zinc towards the roots.

Summary: Phosphorous (P) fixation in saline soils is a global concern. This study investigated the effects of different P sources and rates on winter wheat yield, P uptake, agronomy efficiency, and soil quality in the coastal saline area of China. The results showed that optimizing P sources and rates, with superphosphate (SSP) being the most effective source, can significantly improve wheat yield and P uptake.
