Co-occurring increased phosphatase activity and labile P depletion in the rhizosphere of Lupinus angustifolius assessed with a novel, combined 2D-imaging approach
(Elsevier, 2021-02)
Innovative non-destructive 2D imaging methods such as zymography and diffusive gradients in thin films (DGT) have been developed recently to assess the distribution of phosphatase activity and labile solutes at the root-soil ...
Dairy farm effluent effects on urine patch nitrous oxide and carbon dioxide emissions
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2005)
Dairy farm effluent (DFE) comprises animal feces, urine, and wash-down water collected at the milking shed. This is collected daily during the milking season and sprayed onto grazed dairy pastures. Urine patches in grazed ...
Direct exports of phosphorus from fertilizers applied to grazed pastures
(Crop Science Society of America with the American Society of Agronomy and the Soil Science Society of America, 2019-08-21)
Since its discovery in 1669, phosphorus (P) in the form of fertilizer has become an essential input for many agroecosystems. By introducing a concentrated P source, fertilizers increase short-term P export potential soon ...
The efficacy of good practice to prevent long-term leaching losses of phosphorus from an irrigated dairy farm
(Elsevier, 2019-03-01)
Phosphorus (P) can be leached from intensive land uses, including grazed dairy farming. There is some evidence to suggest that P-leaching can enrich groundwater, especially where fertiliser or farm dairy effluent P (FDE) ...
The mitigation of phosphorus losses from a water-repellent soil used for grazed dairy farming
(Elsevier, 2020-03-15)
Phosphorus (P) losses via surface runoff can be large. Soil water repellency (SWR) occurs in warm and dry conditions. If SWR coincides with P fertiliser applications, the risk of P loss by surface runoff may increase. ...
An assessment of cadmium availability in cadmium-contaminated soils using isotope exchange kinetics
(Soil Science Society of America, 2004)
There has been much research conducted to find suitable methods for the determination of available Cd in soils. In recent years, an isotope exchange kinetics (IEK) technique has been tested to describe the kinetic transfer ...
Kinetics of cadmium and cobalt desorption from iron and manganese oxides
(Soil Science Society of America, 1995)
Oxides of Fe and Mn in soils are capable of sorbing large amounts of trace metal ions and can therefore be important in controlling trace metal concentrations in soil solution, and hence trace metal bioavailability in ...
Fractionation and distribution of arsenic in soils contaminated by cattle dip
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 1998)
Soils surrounding cattle dips in Australia are known to be highly contaminated with As and are potentially of major concern to the environment and human health. A study of 11 dip sites in northern New South Wales (NSW) has ...
Cadmium and cobalt desorption kinetics from soil clays: effect of sorption period
(Soil Science Society of America, 1998)
Soil solution metal concentrations and hence metal bioavailability are controlled by sorption-desorption reactions at the surfaces of soil colloids. Compared with the numerous studies on sorption of metals by soils, there ...
Desorption of copper from some New Zealand soils
(Soil Science Society of America, 1993)
Availability of soil Cu to plants is dependent on the desorption into the soil solution of Cu from the surfaces of soil colloidal materials. Although there have been many studies of Cu sorption by soils, however, few have ...
