chapter on the chemical processes that control P retention and release in soils, em- phasizing how this affects P uptake by plants and the potential for P transport to surface waters.

Electron transfer (redox) reactions, mediated by soil microbiota, modulate elemental cycling and, in part, establish the redox poise of soil systems. Understanding soil redox

This chapter presents an overview of the chemical nature of soil organic phosphorus (P) and its role in determining the dynamics, availability, and mobility of soil P in

The results presented a high match with nutrient changes, in which the five selected soil enzymes: acid phosphatase (S-ACP, P-cycle), sucrose (S-SC, C-cycle), urease (S-UE),

This chapter focuses on the chemical processes that control phosphorus (P) retention and release in soils, emphasizing how this affects P uptake by plants and the potential for P transport to

Reactions controlling the cycling of P in soils- fdi:010008808

A valuable approach to studying phosphorus (P) dynamics in soil-plant systems has been the use of P isotope techniques. Isotope techniques used for studying P cycling in agricultural and

The incorporation of organic matter (OM) in soils that are able to rapidly sorb applied phosphorus (P) fertiliser reportedly increases P availability to plants. This effect has

Phosphate rock (PR) is an alternative fertilizer to increase the P content of P-deficient weathered soils. We evaluated the effects of fertilizer form on indicators of biological

Soil biota play a major role in element cycling in terrestrial systems (Ehrlich and Newman, 2009; Gadd et al., 2012).The bacteria, archaea, and fungi inhabit a wide range of

This chapter provides an overview of the relative contributions of organic and inorganic sources to soil phosphorus (P) accumulation, its dynamics, an

Understanding the biogeochemical cycling of phosphorus (P), particularly organic P (OP) in soils, under varying land use and soil development processes is essential for

Background and aims This study assessed the impact of pH modification of pig slurry on the dynamics of slurry- and soil-derived phosphorus (P) after surface application, as a

Redox cycling, and the behaviour that chemically reduced P compounds exhibit in soils, introduces alternative routes of cycling P that may become more important as the soil

Chemistry, Cycling, and Potential Movement of Inorganic Phosphorus in Soils

According to Belnap , the biological P cycle in dry soil is controlled by the intensity, timing, and amount of precipitation. Water (24.1%) was 0.8 when nucleotides were

As an important part of the soil phosphorus (P) pool, organic P (OP) is widely found in terrestrial and aquatic environments (e.g., soils and sediments). The interfacial behavior of

Siegenthaler, M.B.; Tamburini, F.; Frossard, E.; Chadwick, O.; Vitousek, P.; Pistocchi, C.; Meszaros, E.; Helfenstein, J. 2020: A dual isotopic (P-32 and O-18) incubation study to

Here, we combine sequential extraction with P K -edge X-ray absorption spectroscopy and isotopic methods (33 P and 18 O in phosphate) to characterize P cycling on

Abstract. Quantification of turnover of inorganic soil phosphorus (P) pools is essential to improve our understanding of P cycling in soil–plant systems and improve representations of the P

The chemical nature of P accumulation in agricultural soils

In this formula: Olsen-P is the effective phosphorus content of soil (mg·kg − 1); X is the adsorbed amount of phosphorus (mg·kg − 1); C is the concentration of dissolved

Factors affecting rhizosphere pH are the source of nitrogen supply (NO 3 − vs. NH 4 + uptake), nutritional status of plants (e.g., Fe and P deficiency), excretion of organic acids,

Rising global stoichiometric imbalance between increasing nitrogen (N) availability and depleting phosphorus (P) resources increases the importance of soil microbial P recycling.

We measured acid phosphatase and chitinase (N-acetyl ß-D-glucosaminide) activity in soilacross a chronosequence in Hawaii where N and Pavailability varies substantially

To determine the importance of different biological processes on P cycling, we analyzed the isotopic composition of oxygen in phosphate (δ 18 O-Pi) from the parent material, soil microorganisms, the available P pool, and from the

Microbially mediated soil P cycle is essential for sustaining the processes and functions of some plants can release acids which participate in ligand exchange reactions
