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 ...
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) ...
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 ...
Phosphorus exchangeability and leaching losses from two grassland soils
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2002)
Although phosphate phosphorus (P) is strongly sorbed in many soils, it may be quickly transported through the soil by preferential flow. Under flood irrigation, preferential flow is especially pronounced and associated ...
Fungal inoculum properties : Extracellular enzyme expression and pentachlorophenol removal by New Zealand Trametes species in contaminated field soils
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2007)
This study was conducted to improve the ability of indigenous New Zealand white-rot fungi to remove pentachlorophenol (PCP) from contaminated field soil. The effects of different bioaugmentation conditions on PCP removal ...
Fungal inoculum properties : Extracellular enzyme expression and pentachlorophenol removal in highly contaminated field soils
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2007)
This study was conducted to improve the pentachlorophenol (PCP) bioremediation ability of white-rot fungi in highly contaminated field soils by manipulating bioaugmentation variables. These were the dry weight percentage ...
Seasonal fluctuations in phosphorus loss by leaching from a grassland soil
(Soil Science Society of America, 2004)
Phosphorus losses from soils have been reported to impair the water quality, resulting in deaths of fish and other marine animals, and can harm human health. The objective of this study was to determine the seasonal ...
¹⁵N recoveries from ruminant urine patches on three forage types
(Springer Verlag on behalf of the Royal Netherlands Society of Agricultural Science, 2017-05-17)
Background and aims: ¹⁵Nitrogen balances are useful tools to increase our understanding of soil N processes and the efficiency of plants in taking up animal urine-N. This study aimed to investigate the effect of forage ...
