Phosphorus leaching from an organic and a mineral arable soil in a rainfall simulation study
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2018-05-03)
Phosphorus derived from agricultural systems has been found to cause eutrophication of surface waters. To combat this, the specific location of soil profile P release is necessary for development of effective mitigation ...
Validating novel oligonucleotide primers targeting three classes of bacterial non-specific acid phosphatase genes in grassland soils
(Springer International Publishing, 2018-06)
Background and aims: Microbially driven mineralization of organic phosphorus forms is of particular importance in the soil environment, where it becomes available to plants as inorganic orthophosphates. In acidic soils, ...
Nitrous oxide emissions and biogeochemical responses to soil freezing-thawing and drying-wetting
Soil freeze-thaw (FT) and dry-wet (DW) cycles are brief transitory biophysical changes, but these events have important implications in determining the timing and magnitude of N₂O emissions and may represent a significant ...
Plant biomass management impacts on short-term soil phosphorus dynamics in a temperate grassland
(Springer-Verlag on behalf of the International Society of Soil Science, 2018-04)
The objective of this study was to quantify the combined effects of long-term plant biomass retention/removal and environmental conditions on soil microbial biomass phosphorus (P), bioavailable P, and acid phosphomonoesterase ...
Reducing nitrogen leaching losses in grazed dairy systems using an Italian ryegrass-plantain-white clover forage mix
(Wiley on behalf of the British Grassland Society and the European Grassland Federation, 2018-12)
In grazed agricultural systems, animal urine patches are the major source of nitrogen (N) leaching losses and can cause a decline in water quality. Urine-N rates often exceed plant requirements, and there is a need for ...
Impacts of long-term plant biomass management on soil phosphorus under temperate grassland
(Springer International Publishing AG, 2018-06)
Aims: We assessed and quantified the cumulative impact of 20 years of biomass management on the nature and bioavailability of soil phosphorus (P) accumulated from antecedent fertiliser inputs. Methods: Soil (0–2.5, 2.5–5, ...
