Inorganic phosphorous, lime and vermicompost induced changes on phosphorus fractions and other properties of acidic Soil of Cheha district, Ethiopia

In acid soils, soluble inorganic phosphorus is fixed by aluminum and iron, so that phosphorous availability to plants would be inhibited. Thus, an incubation study was conducted to evaluate the effects of lime, vermicompost, and mineral P fertilizer on the distribution of P fractions, oxalate, dithi...

Description
Summary:In acid soils, soluble inorganic phosphorus is fixed by aluminum and iron, so that phosphorous availability to plants would be inhibited. Thus, an incubation study was conducted to evaluate the effects of lime, vermicompost, and mineral P fertilizer on the distribution of P fractions, oxalate, dithionite extractable aluminum, and iron. The treatments consisted of three rates of phosphorous (0, 74.51, and 149.01 kg P ha-1), three rates of vermicompost (0, 5, and 10 ton VC ha-1), and four rates of lime (0, 5.70, 9.20, and 11.50 ton CaCO3 ha-1). The experiment was laid out as a complete randomized design in a factorial arrangement. The results revealed that the combined application of lime, vermicompost, and mineral P significantly (p
