Evidence for the leaching of dissolved organic phosphorus to depth
(Elsevier, 2021-02-10)
Phosphorus (P) can leach from topsoil in inorganic and organic forms. While some evidence has shown inorganic P (orthophosphate) can leach to depth in some soils, less is known of dissolved organic P (DOP). This is not ...
Likely controls on dissolved reactive phosphorus concentrations in baseflow of an agricultural stream
(Springer, 2020-05-06)
Purpose: High baseflow phosphorus (P) concentrations increase the likelihood of periphyton blooms. Several physical and chemical factors can control baseflow P concentrations such as hydraulic exchange with groundwater, ...
The performance of an efficient dairy system using a combination of nitrogen leaching mitigation strategies in a variable climate
(Elsevier, 2017-12-01)
An efficient dairy system, that implemented a combination of nitrogen (N) leaching mitigation strategies including lower N fertilizer input, standing cows off pasture for part of the day in autumn and winter (stand-off), ...
The potential of L. scoparium, K. robusta and P. radiata to mitigate N-losses in silvopastural systems
(Elsevier Ltd, 2017-06)
Silvopastoral systems aim to enhance economic, cultural and social principles by sustainably combining forest management with agriculture. In these typically high-nitrogen (N) environments, plant species selection can ...
Trace metal mobilization by organic soil amendments: Insights gained from analyses of solid and solution phase complexation of cadmium, nickel and zinc
(Elsevier, 2018-05)
The accumulation of Cd in soils worldwide has increased the demand for methods to reduce the metal's plant bioavailability. Organic matter rich soil amendments have been shown to be effective in achieving this. However, ...
IUSS SUITMA 6 International Symposium 2011
(Springer-Verlag, 2013-03)
Soils in urban, industrial, traffic, mining and military areas (SUITMA) is a working group of the International Union of Soil Sciences created in 1998 to increase and promote soil science in strongly anthropized areas ...
The influence of a flood event on the potential sediment control of baseflow phosphorus concentrations in an intensive agricultural catchment
(Springer-Verlag, 2018-06-23)
Purpose: The growth of periphyton in streams is enhanced by phosphorus (P) in baseflow. The likely control of P concentrations in baseflow can be approximated by the equilibrium P concentration (EPC₀) of bed sediments. ...
Carbonaceous soil amendments to biofortify crop plants with zinc
(Elsevier, 2013)
Carbonaceous soil amendments, comprising mixtures of biosolids and biochar, have been demonstrated to improve fertility while reducing nitrate leaching. We aimed to determine the efficacy of a biosolids/biochar soil amendment ...
Speciation and distribution of organic phosphorus in river sediments: a national survey
(Springer, 2015-12)
© 2015, Springer-Verlag Berlin Heidelberg. Purpose: Organic phosphorus (P) can play a role in in-stream productivity (e.g., periphyton or macrophyte growth), but little is known of the largest likely source of organic P—bed ...
Mechanisms of pollution induced community tolerance in a soil microbial community exposed to Cu
(Elsevier B.V., 2014-07)
Pollution induced community tolerance (PICT) to Cu²⁺, and co-tolerance to nanoparticulate Cu, ionic silver (Ag⁺), and vancomycin were measured in field soils treated with Cu²⁺ 15 years previously. EC₅₀ values were determined ...
