Implications of applied best management practice for peatland forest harvesting
(Elsevier (ScienceDirect), 2013-12-20)
Elevated levels of nutrients and suspended sediment (SS), and changes to other environmental parameters, are frequently associated with forestry harvesting (clearfelling) operations, and are indicative of the potentially ...
Evaluation of chemical amendments to control phosphorus losses from dairy slurry
(Wiley, 2011)
Land application of dairy slurry can result in incidental losses of phosphorus (P) to runoff in addition to increased loss of P from soil as a result of a buildup in soil test P (STP). An agitator test was used to identify ...
Impact of chemical amendment of dairy cattle slurry on phosphorus, suspended sediment and metal loss to runoff from a grassland soil.
(Science of the Total Environment, 2011-11-01)
Emerging remediation technologies such as chemical amendment of dairy cattle slurry have the potential to reduce phosphorus (P) solubility and consequently reduce P losses arising from land application of dairy cattle ...
Use of zeolite with alum and PAC amendments to mitigate runoff losses of P, N and suspended solids from agricultural wastes applied to land
(ASA, CSSA, and SSSA, 2015)
Diffuse pollutant losses containing phosphorus (P), nitrogen (N) and suspended solids (SS) can occur when agricultural wastes are applied to soil. This study aimed to mitigate P, N and SS losses in runoff from grassed ...
Contrasting yield responses to phosphorus applications on mineral and organic soils from extensively managed grasslands: Implications for P management in high ecological status catchments
(Wiley, 2018-09-13)
Phosphorus (P) loss from grassland production is one of the main causes affecting high status water bodies in Europe. Soils with a high content in organic matter (OM), even if extensively managed, are particularly vulnerable ...
Optimizing nitrate removal and evaluating pollution swapping trade-offs from laboratory denitrification bioreactors
(Elsevier, 2014-10-29)
Denitrification bioreactors, typically containing woodchips, are artificial sinks used to remediate nitrate (NO3-) losses on agricultural landscapes. Analysis of these bioreactors frequently considers their efficacy in ...
Nutrient, metal and microbial loss in surface runoff following treated sludge and dairy cattle slurry application to an Irish grassland soil
(Elsevier, 2015)
Treated municipal sewage sludge ( biosolids ) and dairy cattle slurry (DCS) may be applied to agricultural land as an organic fertiliser. This study investigates losses of nutrients in runoff water (nitrogen (N) and ...
Nitrate removal rate, efficiency and pollution swapping potential of different organic carbon media in laboratory denitrification bioreactors.
(Ecological Engineering, 2012-01-01)
Laboratory denitrifying bioreactors, which use an organic carbon (C) rich media to enhance microbial reduction of nitrate (NO3-) to nitrogen (N) gases, are used worldwide to protect surface and groundwater. To highlight ...
Consequences of varied soil hydraulic and meteorological complexity on unsaturated zone time lag estimates.
(Elsevier, 2014-10-13)
The true efficacy of a programme of agricultural mitigation measures within a catchment to improve water quality can be determined only after a certain hydrologic time lag period (subsequent to implementation) has elapsed. ...
