Root zone losses are just the beginning
(Fertilizer and Lime Research Centre, 2014-02)
Minimising root zone losses has rightly been the main focus in recent years of measures to reduce agricultural land use impacts on freshwater quality. However, root zone losses are just the beginning, as far as managing ...
Fate of a dairy cow urine pulse in a layered volcanic vadose zone
(Fertilizer and Lime Research Centre, 2013-02)
Nitrate-N leaching from dairy cow urine patches has been identified as one of the major contributors to groundwater contamination and degradation of surface waters in dairying catchments. To investigate the transport and ...
Multi-pronged approach to elucidate nitrate attenuation in shallow groundwater
(Fertilizer and Lime Research Centre, 2015-02)
It is increasingly being recognised in New Zealand that denitrification occurring in the groundwater zone can result in a substantial reduction of the nitrate load leached from agricultural land before this load can reach ...
Critical pathways programme: Unravelling sub-catchment scale nitrogen delivery to waterways
(Fertilizer and Lime Research Centre, Massey University, 2019)
To be effective and efficient, decision making on land use, land management, mitigation measures, as well as policy, need to be based on a clear understanding of cause-effect relationships. Present practice is to link ...
Transfer Pathways Programme (TPP) : New research to determine pathway-specific contaminant transfers from the land to water bodies
(Fertilizer and Lime Research Centre, 2016-02)
Land use (source) can only be defensibly linked to an effect on a receiving water body (receptor) if the critical transfer pathways and the hydrological and biogeochemical processes that occur along them are understood. ...
