The efficacy of good practice to prevent long-term leaching losses of phosphorus from an irrigated dairy farm
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 gas diffusivity controls N₂O and N₂ emissions and their ratio
(Soil Science Society of America, 2016-05-06)
Knowledge of soil biological and physical interactions with respect to N₂O and N₂ fluxes is essential to ensure that agricultural land management is environmentally and economically sustainable. This study determined how ...

Effects of lime and organic amendments derived from varied source materials on cadmium uptake by potato
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, Inc., 2017-07)
Repeated applications of Cd-rich phosphate fertilizers have resulted in elevated concentrations of this toxic element in some New Zealand soils. Exceedance of the food safety standard for Cd (0.1 mg kg⁻¹ fresh weight) has ...
