The mitigation of phosphorus losses from a water-repellent soil used for grazed dairy farming
Phosphorus (P) losses via surface runoff can be large. Soil water repellency (SWR) occurs in warm and dry conditions. If SWR coincides with P fertiliser applications, the risk of P loss by surface runoff may increase. ...
Soil biodiversity and biogeochemical function in managed ecosystems
A complex combination of environmental, biological, chemical, and physical properties and processes determine soil biodiversity and its relationship to biogeochemical functions and ecosystem services. Vegetation, land-use, ...
Irrigation effects on soil organic carbon under a ryegrass-white clover pasture on a Lismore stony silt loam soil : A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University
(Lincoln University, 2020)
Long-term summer irrigation of temperate managed pastures has been reported to either increase or decrease soil organic carbon (SOC) stocks when compared with dryland systems. Understanding the short-term effects of ...
Quantifying contaminant losses to water from pastoral land uses in New Zealand III. What could be achieved by 2035?
(Taylor & Francis on behalf of the Royal Society of New Zealand, 2020-11-11)
To meet the water quality outcomes sought by catchment communities and regulators, the losses of nitrogen (N), phosphorus (P) and sediment from dairy and sheep/beef farms must be reduced across many catchments. We conducted ...
Soil microbial community restructuring and functional changes in ancient kauri (Agathis australis) forests impacted by the invasive pathogen Phytophthora agathidicida
New Zealand's culturally iconic, ancient kauri (Agathis australis) forests are threatened with extinction as a result of dieback caused by an invasive and highly virulent soil-borne pathogen (Phytophthora agathidicida). ...
