McDowell, Richard; Gray, Colin W.; Cameron, Keith C.; Di, Hong J.; Pellow, R. (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) ...

Using organic phosphorus to sustain pasture productivity: A perspective

Nash, D. M.; Haygarth, P. M.; Turner, B. L.; Condron, Leo M.; McDowell, Richard; Richardson, A. E.; Watkins, M.; Heaven, M. W. (Elsevier, 2014-06)

Organic phosphorus (P) in grazed pastures/grasslands could sustain production systems that historically relied on inorganic P fertiliser. Interactions between inorganic P, plants and soils have been studied extensively. ...

Effects of lime and organic amendments derived from varied source materials on cadmium uptake by potato

Mamun, Shamim Al; Lehto, Niklas; Cavanagh, J.; McDowell, Richard; Aktar, M.; Benyas, E.; Robinson, Brett (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 ...
