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) ...
Environmental parameters affecting the concentration of iodine in New Zealand pasture
(American Society of Agronomy, Crop Science Society of America & Soil Science of America, 2019-08-21)
Iodine (I) is an essential trace element commonly deficient in agricultural systems. Whereas there is much information on I in food crops, there is a lacuna of knowledge on the environmental factors that affect pasture I ...
Density effects on soil-water characteristics, soil-gas diffusivity, and emissions of N₂O and N₂ from a re-packed pasture soil
(Soil Science Society of America, 2019-02)
Density-induced soil structural changes may potentially alter both soil total porosity and soil pore size distribution, and thus change the soil’s water retention characteristics, gas diffusion and transport properties, ...
Soil-gas diffusivity and soil-moisture effects on N₂O emissions from intact pasture soils
(Wiley on behalf of the Soil Science Society of America, 2019-07)
Grazed pastures are recognized as a dominant source of nitrous oxide (N₂O), a highly potent greenhouse gas. Studies have examined soil physical controls on N₂O emissions, including soil moisture status. Limited attempts ...
Residue retention and minimum tillage improve physical environment of the soil in croplands: A global meta-analysis
(Elsevier on behalf of International Soil Tillage Research Organization (ISTRO), 2019-11)
Conservation tillage practices, here defined as no-tillage (NT) or reduced tillage (RT) with/without residue retention, have been widely used to alleviate the negative effects caused by intensive tillage practices. ...
