Co-occurring increased phosphatase activity and labile P depletion in the rhizosphere of Lupinus angustifolius assessed with a novel, combined 2D-imaging approach
Innovative non-destructive 2D imaging methods such as zymography and diffusive gradients in thin films (DGT) have been developed recently to assess the distribution of phosphatase activity and labile solutes at the root-soil ...
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. ...
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 ...
Increased soil nitrogen supply enhances root-derived available soil carbon leading to reduced potential nitrification activity
Nitrogen (N) immobilisation by heterotrophic microorganisms is critical for reducing N losses from soils and ensuring a long-term supply of N to plants in grassland ecosystems. The supply of carbon (C) available to soil ...
The influence of rock fragments on field capacity water content in stony soils from hard sandstone alluvium
Worldwide, rock fragments (RFs) are generally considered inert with respect to bulk soil hydraulic properties, such that all soil water retention properties predicted by national pedotransfer functions (such as S-map) are ...
