Phosphorus Sorption Parameters of Soils and Their Relationships with Soil Test Phosphorus

Development of phosphorus sorption capacity‐based environmental indices for tile‐drained systems

“…This suggests that an increase in pH would reduce PSC of the soils as observed in previous PSC studies in acidic to near‐neutral soils (Houben et al., 2011; Maguire et al., 2001). Finally, no sigificant relationship existed between Mehlich‐3 P and PSI (Table 2), which was consistent with previous studies (Laboski & Lamb, 2004; Wang, O'Halloran, Zhang, Hu, & Tan, 2015). This observation is understandable considering a soil's PSC is generally linked to exchangeable Fe, Al, and Ca concentrations, OM content, soil pH, clay content, and clay mineralogy (Laboski & Lamb, 2004; Renneson et al., 2015; Wang et al., 2015).…”

Relation between various soil phosphorus extraction methods and sorption parameters in calcareous soils with different texture

“…It is possible that the positive influence of organic matter on P sorption capacity was in association with Ca 2+ and Mg (Ige et al, 2005;Pizzeghello et al, 2014). No significant correlation found between extractable P using different extrcatants and Q max , which was consistent with previous reports (Laboski and Lamb, 2004;Wang et al, 2015). In this work, EPC 0 values ranged from 0.09 to 2.74 mg L −1 (Table 3), and are in the range (0.28-1.70 mg L −1 ) found by Zhou and Li (2001) for calcareous soil collected from vegetable field and fruit grove in southern Florida.…”

“…This method has been used as the basis for calculating soil DPS (Breeuwsma and Reijerink, 1992;Schoumans and Groenendijk, 2000), but other researchers have proposed other extractants including Mehlich-1, Mehlich-3 and Olsen P (Nair et al, 2004;Maguire and Sims, 2002;Khiari et al, 2000;Wang et al, 2015). The Mehlich-3 extractant is commonly used for extracting P, Al, Fe, and other elements (Allen and Mallarino, 2006).…”

Characterization of Phosphorus in Fresh and Composted Manures of Different Livestock

“…Phosphorous absorption by soil is highly important for management practices, depending on different transport factors like soil hydrological conductivity, precipitation, slope, and distance, along with integration, which plays an important role in P absorption [50]. Leaching of P and other elements from manure to water sources may affect surface water quality [51][52].…”
