Rates and microbial communities of denitrification and anammox across coastal tidal flat lands and inland paddy soils in East China
(Elsevier, 2021-01-01)
Denitrification and anammox are the main pathways of N loss in wet habitats while their relative contribution to N₂ production and underlying microbial mechanisms across marine-terrestrial ecotone remain unclear. Here we ...
Yield-scaled nitrous oxide emissions from nitrogen-fertilized croplands in China: A meta-analysis of contrasting mitigation scenarios
(Elsevier and Science Press on behalf of Soil Science Society of China, 2021-04)
Nitrogen (N) losses in cropland resulting from the application of synthetic fertilizers decrease crop productivity and exacerbate environmental pollution. Mitigation measures, such as reduction in N fertilizer application ...
The spatial coverage of dairy cattle urine patches in an intensively grazed pasture system
(Cambridge University Press, 2010-12-23)
Accurate field data on the paddock area affected by cow urine depositions are critical to the estimation and modelling of nitrogen (N) losses and N management in grazed pasture systems. A new technique
using survey-grade ...
Small-scale spatial variability of selected soil biological properties
(Elsevier, 2004-04)
A strategy for sampling soil from intact monolith lysimeters was established based on measurements of spatial heterogeneity within the lysimeter area. This was part of an ongoing study to determine relationships between ...
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) ...
Influence of organic and mineral amendments on microbial soil properties and processes
(Elsevier, 2007-01)
Microbial diversity in soils is considered important for maintaining sustainability of agricultural production systems. However, the links between microbial diversity and ecosystem processes are not well understood. This ...
Nitrous oxide emissions from urea fertiliser and effluent with and without inhibitors applied to pasture
(Elsevier Masson, 2016-03-01)
© 2015 Elsevier B.V.There is currently a limited number of New Zealand studies quantifying nitrous oxide (N₂O) emission factors (EF₁, N₂O emissions as a percentage of N applied) for farm dairy effluent (FDE) and urea ...
Italian ryegrass swards reduce N leaching via greater N uptake and lower drainage over perennial ryegrass cultivars varying in cool season growth rates
(Taylor & Francis on behalf of the Royal Society of New Zealand, 2018-02-04)
Pasture mitigation strategies are needed to reduce the negative effects of nitrate (NO₃⁻) leaching from intensive pastoral livestock production systems. We explored the capability of pasture grasses with different cool ...
Potential inhibition of urine patch nitrous oxide emissions by Plantago lanceolata and its metabolite aucubin
(Taylor & Francis on behalf of the Royal Society of New Zealand, 2017-12-12)
Plantain (Plantago lanceolata L.), a forage used in grazed pastures, contains active secondary metabolites that could potentially inhibit nitrification, a key step in nitrous oxide (N₂O) production from grazing ruminant ...
Cattle diet and winter plant growth effects on nitrogen losses from cattle urine patches
(Springer Nature, 2020-04-01)
Nitrogen (N) losses from agricultural land is a major environmental concern, as N leaching can cause eutrophication and nitrous oxide (N₂O) is a greenhouse gas. A lysimeter experiment was undertaken to investigate the ...
