Organic phosphorus (Po) may play a vital role in availability via its mineralization by alkaline phosphatase (ALP), being encoded phoD gene, calcareous soil. Understanding the effects of long-term fertilization on community harboring bacteria and related alteration P owing to changes ALP secretion offer chance elucidate Po contribution soil available P. Based experiment, we analyzed gene microb...

Abstract Phosphorus (P) cycling in paddy soil is closely related to iron (Fe) redox wheel; its availability rice has thus generally been ascribed Fe minerals reductive dissolution. However, the literature aimed identify best method for predicting available P does not uniformly point reductants. Rice plants can indeed solubilize and absorb through many strategies as a function of supply, modifyi...

Soils with continuous application of fertilizer phosphorus (P) may present high accumulations P and be at risk loss. In this study, we investigated the effects different fertilization strategies on soil dynamics in three typical cropland soils over broad spatiotemporal scales China. The speciation (characterized both by Hedley fractionation 31P nuclear magnetic resonance (31P NMR)) sorption cha...

Growing evidence has emerged that cover crops may be able to improve phosphorus (P) cycling and contribute the P nutrition of subsequent crop. This could particularly important in farming systems, with limited access inputs where low soil availability been identified. In a pot experiment using soils labelled radioactive 33P, we examined how range crop residues directly uptake ryegrass, as well ...

Proper and effective management of soil nutrients requires assessment of their variability at the field scale. We compare the effects of lime amendment rate on the spatial variability of three macronutrient forms (NH4 (+)-N, Olsen P, and Mehlich-1 K) in a paddy soil at three different dates during the growth period of a rice crop. The field work was carried out near Corrientes, Argentina. Lime ...

information about forms of phosphorus (p) is important for the evaluation of p status in soil and also understanding of the soil fertility and plant nutrition. to obtain such information and to determine the relationship between the p forms from soil characteristics, amount of different organic and inorganic p forms of 20 soil composite samples of eastern azerbaijan province, iran were determin...

Introduction Continuous monoculture leading to soil nutrient depletion may cause a decline in plantation productivity. Cow dung is typically used as cheap renewable resource improve status. In this study, our purpose was compare the effects of different cow return methods (direct and carbonization return) on microbial communities phosphorus availability root zone (rhizosphere non-rhizosphere so...
