| Özet |
| Land use has a potential effect on phosphorus (P) distribution in the profile and the fractions of P in the soils. The conversion of native ecosystems into agricultural use may alter the fractions of the soil-P. In this study, changes in soil organic and inorganic P fractions in the native grassland (Gr), 5-year (C5), and 20-year (C20) cultivated fields, converted from grassland to arable sites were evaluated using a sequential extraction procedure. Six soil P fractions were separately quantified: the most available P (water-extractable P; H2O-P), available P (NaHCO 3-extractable organic and inorganic P; NaHCO3-Po and NaHCO3-Pi), medium available P (NaOH-extractable organic and inorganic P; NaOH-Po and NaOH-Pi), poorly soluble Ca-bound P (HCl-extractable P; HCl-P), the most resistant and insoluble P (Res-P), and the sum of the P in all fraction (Pt). The Pt, Res-P,available and medium available P were higher (p < 0.01) in the Gr site than that in the C5 and C20 sites, whereas the lower HCl-P was obtained in the Gr site. The P fractions were similar in the C5 and C20 except the HCl-P, Pt, and NaHCO3-Pi, suggesting that most of the decline in P fraction occurred during the first 5 years of cultivation. While cultivation led to a marked increase in the proportion of the Res-P and HCl-P to Pt, it conversely resulted in a gradual decrease in the ratio of organic bound P. These results indicated that both organic and inorganic P fractions substantially decreased (except the H2O-P and Olsen-P) in the cultivated sites compared to the Gr site. Thus, to maintain soil P status in the agricultural sites converted from native grassland, is the need for sustainable P management systems. Copyright © Taylor & Francis Group, LLC. |
