“…For instance, Maranguit et al (2017) discovered that soil available P fractions (i.e., H 2 O-Pi, NaHCO 3 -Pi and NaHCO 3 -Po) were positively correlated with SOC (r = .70-.82, p < .001). In agreement with this, we found that soil Olsen-P, resin-P and NaHCO 3 -P were positively correlated with SOC in cropland while HCl-P (r = .54, p < .05) was significantly related to CaCO 3 content (Figures 5a and 6a), suggesting that SOC plays a key role in influencing soil P transformation (Uygur et al, 2017). Coincidently, the close relationship between P fractions (CaCl 2 -P) and soil Olsen-P (r = .82, p < .01) was observed in a long-term field calcareous soil (Jalali & Tabar, 2011;Milić et al, 2019).…”

Phosphorus (P) fertilizers have long been applied in agriculture. However, the influence of long‐term P addition on the evolution of soil P fertility and legacy P characteristics have not been well‐documented. Herein, literature data were collected from the Chinese National Knowledge Infrastructure Database (CNKI) to explore the evolution of soil P fertility after 33 years of application of P fertilizer; different soil samples were collected from cropland and adjacent uncultivated land to analyse the distribution of P fractions at different soil depths (0–0.8 m) using Guppy's sequential P extraction method. We found that soil Olsen‐P significantly increased by 3.6‐fold (from 7.2 mg kg−1 in 1981 to 25.9 mg kg−1 in 2013) after 33 years of P application, while total P increased slightly. The ratios of inorganic P fractions in cropland to those uncultivated land followed NaHCO3‐P (1.47) > NaOH‐P (1.38) > resin‐P (1.37) > residue‐P (1.17) > HCl‐P (1.11), suggesting that long‐term P addition contributed more to labile and moderately labile P rather than non‐labile P. Moreover, a principal component analysis could distinguish between cropland and uncultivated land, indicating that long‐term application of P fertilizer changed soil P characteristics. Compared to uncultivated land, soil NaHCO3‐P in cropland was closely associated with soil organic C, total nitrogen and carbonate. Collectively, our findings highlight that soil legacy P was notably increased after long‐term of P application, and a large portion of the applied P remained in labile and moderately labile forms. Therefore, soil legacy P can be recommended as a useful P management tool.

“…Positive relationship is the function of the adsorption mechanisms, as previously mentioned, with the surface bound to this fraction (usually bound to Fe and Al, OH surfaces) and the decrease in clay quantity. Uygur et al 22 found significant relationships between Fe and Al and NaOH-Pi that could be extrapolated by CBD. In this respect, surfaces of oxide minerals are an important component in the adsorption of mineral P 8,23,25 .…”
