The Conversion of Inorganic Phosphorus Fractions, Phosphatase Activity, and Some Biological Properties in Sandy Soil Enriched with Minerals, Organic Matter, and Microbial Modifiers under Two Months of Incubation
This study investigated the effect of the inoculation of the soil with some phosphorus solubilizing microorganisms (PSM) on inorganic P fractions in sandy soil enriched with inorganic and organic amendments. A factorial experiment arrangement was performed in a completely randomized design with three replications, using two factors: microorganisms (control, Entrobacter cloacae, Brevundimonas, a...
متن کاملFertilizer effects on phosphorus fractions and organic matter in Andisols
Andisols are characterized by a high phosphorus (P) fixation capacity, which is a limiting factor for plant production. Continuous application of P fertilizer may result in an accumulation of P associated with soil organic matter (SOM), which further acts to reduce the availability of the added P. The objectives of this study were (1) to evaluate the impact of P fertilizer inputs on the quantit...

متن کاملPhosphorus fractions in soil with a long history of organic waste and mineral fertilizer addition
Bragantia, Campinas, v. 76, n. 1, p.155-166, 2017 AbstrAct: Applications for long periods of organic animal waste as a source of nutrients to crops can contaminate the soil and the surface and subsurface waters. This study aimed to evaluate how the utilization of organic waste, after successive applications, affects P fractions in the soil and consequently environmental contamination. In an exp...
متن کاملDoes Soil Disturbance Affect Soil Phosphorus Fractions?
Increased turnover of organic matter as a result of soil disturbance (e.g. by soil tillage) is described in principle, but the direct influence of soil disturbance on soil P turnover especially for organic farming systems has not been sufficiently proven. The objective of the study was to evaluate the short term effect of soil disturbance on different soil P fractions in a soil shaking experime...
