Dynamics of phosphorus fractions in soils treated with dairy manure

Abstract: The evaluation of phosphorus (P) transformations in soil after application of manure or mineral P can improve soil management and optimise P use by plants. The objectives of the present study were to assess organic and inorganic P forms in two soils treated with dairy manure and triple superphosphate and to establish relationships between soil P fraction levels and P availability. Soil organic and inorganic P fractions were quantified using a pot experiment with two soils, a typical Hapludox and an arenic Hapl… Show more

“…It then transforms into less labile P fractions and utilized by crop plants. Therefore, the P availability of both soils amended with superphosphate was higher than that of soil with the recycled fertilizers (Braos et al, 2020).…”

“…1). Previous studies have shown that the level of soil available P remains stable following cattle manure application (Mkhonza et al, 2020), but was found decreased when mineral P fertiliser was used (Braos et al, 2020). Some studies suggest that long-term straw retention in the soil improves the content of soil available P Cao et al, 2021).…”

“…Microbial biomass P may play a leading role in P cycle and thus contributing to the activation and utilization of inorganic P, especially in soils with relatively higher organic carbon contents (Wu et al, 2003;Ahmed et al, 2019). Phosphorus fractionation method modified by Tiessen & Moir (1993) from that proposed by Hedley, Stewart & Chauhan (1982) took into account the fractions of both inorganic P and organic P and its availability to crops, and thus has been widely adopted to quantitatively evaluate soil P fractions and transformations under different soil types, cropping systems, tillage practices and fertilization management regimes (Cross & Schlesinger, 1995;Negassa & Leinweber, 2009;Yan et al, 2016;Braos et al, 2020).…”
