Summary: This study investigated the effects of three different fertilizers on soil phosphorus (P) species through sequential chemical extraction (SCE) and 31P NMR techniques, as well as the degree of P saturation (DPS) in paddy and vegetable fields. The results showed that biochar-blended organic fertilizer and organic fertilizer increased the total and available P contents in the soil, but decreased the DPS values. However, chemical fertilizer had a smaller impact on soil P species. Biochar-blended organic fertilizer improved P availability and decreased P loss risk through the alteration of soil P species.

Summary: This study found that using different phosphorus fertilizers can reduce phosphorus leaching in sandy soil. Among them, poultry manure and sheep manure pose the highest leaching risk, while substituting Sanandaj sludge or its biochar for highly soluble fertilizers can lower the leaching risk and retain more phosphorus in the soil.

Summary: This study investigated the migration and transformation behavior of pollutants in phosphorus ore flotation tailings (PTs). The solidification/leaching mechanism of PTs treated with nine different materials was simulated and studied. PAC, FeSO4, and MgO showed good stabilization/solidification efficiency for phosphorus, fluoride, and heavy metals. The migration and transformation of pollutants were influenced by the concentrations of Ca2+ and Mg2+, as well as the Fe3+/Fe2+ ratio and acid-base conditions.

Summary: This study proposed a simplified soil phosphorus extraction technique to evaluate the content and characteristics of various forms of P in soil. The results showed that P inputs significantly increased the levels of all soil P fractions, leading to significant increases in P saturation and legacy P. The study demonstrated the potential value of the proposed methodology in providing comprehensive soil P data.

Summary: Two different environments in an electrochemical process enable simultaneous leaching and recovery of phosphorus from municipal whole digestate. The proposed electrochemical phosphorus recovery cell (EPRC) achieved a high leaching efficiency of 93.3% through acidification, and precipitated nearly 99% of the leached phosphorus using native metals in the cathode chamber. The EPRC demonstrated the feasibility of recovering phosphorus from phosphorus-rich solid wastes.

Summary: Subsurface losses of colloidal and truly dissolved phosphorus (P) from arable land can cause ecological damage to surface water. We studied a drained lowland catchment in Germany to investigate the transport of subsurface particulate P from inland sources to brooks. Our results showed that particulate P and truly dissolved P were the main forms of P in the samples, with colloidal P contributing a smaller proportion. During flow events, particulate P was the dominant form of P, while during baseflow conditions, truly dissolved P was almost negligible. We also found that the transported colloids originated from water-extractable nanocolloids in the C horizon, which were mainly composed of clay minerals.

Summary: This study used five different sewage sludges as phosphorus fertilizers for cucumber plants, and investigated their effects on phosphorus uptake as well as the availability and speciation of phosphorus in rhizosphere and non-rhizosphere soils. The results showed that adding different sewage sludges increased shoot dry weight and phosphorus content in roots and shoots. Additionally, the study found differences in phosphorus content and speciation between rhizosphere and non-rhizosphere soils.

Summary: Research findings suggest that in calcareous soils with diverse properties, the transfer of heavy metals from soil to cabbage can be influenced by adding different types of sludge. Cabbage plays a significant role in the absorption of metals such as cadmium, copper, and zinc, making it a potential choice for phytoremediation of heavy metal-contaminated calcareous soils.

Summary: Long-term use of phosphorus fertilizers can lead to phosphorus leaching from agricultural soils, causing water pollution and eutrophication. This laboratory study investigated the effect of different concentrations of monopotassium phosphate (MKP) on phosphorus and cation leaching from two agricultural soils. The results showed that increasing MKP concentration decreased pH and calcium concentration in leachates, but increased electrical conductivity, sodium, and potassium concentrations. Appropriate MKP concentrations can help reduce phosphorus loss.

Summary: Soils in areas with intensive agriculture have high potassium levels, which may lead to potassium being transferred to groundwater through leaching. This study evaluated the extractability and leaching of potassium from soils using various extractants, and calculated change points to predict the rate of potassium leaching. The findings recommend using specific extractants like CaCl2, HNO3, and H2O to assess the risk of potassium losses, and suggest using calculated degree of potassium saturation as an environmental indicator for evaluating the possibility of potassium leaching.

Summary: The long-term application of organic and inorganic fertilizers can lead to contamination of greenhouse soils with heavy metals. This study found that greenhouse soils had lower adsorption capacity for heavy metals compared to agricultural soils, making them more susceptible to leaching. The desorption experiments showed that the percentage of heavy metal desorption increased with higher concentrations of added heavy metals. The findings suggest that continuous vegetable production and fertilizer application in these greenhouse soils can result in changes in soil properties and heavy metal mobility, posing risks to human health and groundwater quality.
