Nitrous oxide fluxes, soil oxygen, and denitrification potential of urine- and non-urine-treated soil under different irrigation frequencies
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, Inc., 2016-07)
© American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America. 5585 Guilford Rd., Madison, WI 53711 USA. All rights reserved. Despite increased use of irrigation to improve forage ...
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) ...
Soil water extraction patterns of lucerne grown on stony soils
(Springer-Verlag on behalf of the Royal Netherlands Society of Agricultural Science, 2017-05)
Background and aims: Lucerne (Medicago sativa L.) is often grown under water-limited production conditions due to its capacity to extract water from deep soil layers through an extensive taproot system. These soils often ...
Flooding-induced N₂O emission bursts controlled by pH and nitrate in agricultural soils
(Elseiver, 2014-02)
Agricultural soils are a major source of the greenhouse gas nitrous oxide (N₂O) to the atmosphere. Increasing frequency and severity of flooding as predicted for large intensively cropped areas may promote temporary ...
A review of the cost-effectiveness and suitability of mitigation strategies to prevent Phosphorus loss from dairy farms in New Zealand and Australia
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, Inc., 2012-05)
The loss of phosphorus (P) from land to water is detrimental to
surface water quality in many parts of New Zealand and Australia.
Farming, especially pasture-based dairying, can be a source of P
loss, but preventing it ...
Sixty years of seasonal irrigation affects carbon storage in soils beneath pasture grazed by sheep
(Elsevier BV, 2012-02-15)
For sixty years at Winchmore, South Island, New Zealand (43°48′S, 171°48′E, 160 masl), stoney soils under continuous pasture grazing by sheep have received rainfall (nil irrigation) or rainfall and irrigation as required ...
The effect of soil moisture extremes on the pathways and forms of phosphorus lost in runoff from two contrasting soil types
(CSIRO Publishing, 2017)
Soil moisture and Olsen P concentrations play an important role in phosphorus (P) losses in runoff. Under moisture-rich anaerobic conditions, the reduction of Fe-oxides dissolves P from the soil into solution that may be ...
Relationship between sediment chemistry, equilibrium phosphorus concentrations, and phosphorus concentrations at baseflow in rivers of the New Zealand National River Water Quality Network
(American Society of Agronomy, Inc., 2015-05)
Stream sediments can act as a source or a sink of dissolved (filtered) phosphorus (P) via abiotic and biotic processes. The cumulative action and magnitude of abiotic processes has been quantified by the equilibrium P ...
