A synergistic mitigation technology for nitrate leaching and nitrous oxide emissions for pastoral agriculture
Report on a mitigation technology which is synergistic for the reduction of both NO3 leaching and N2O emissions and also for the improvement of pasture yield.
Effect of urine, potassium and dicyandiamide (DCD) application on pasture production from a free-draining Canterbury dairy pasture soil
(Fertiliser and Lime Research Centre, 2014)
A cut-and-carry trial was conducted on a low Quick-test potassium (QTK ≤ 4) Lismore soil during 2012-13 in Springston, Canterbury to test the responsiveness of a dairy pasture to urine, dicyandiamide (DCD) and potassium ...
Monitoring effects of Southland demonstration farm on stream water nitrate
The objective of this research work was to monitor the effects of the Southland Demonstration Farm on the concentration and amount of nitrate in the Tomoporakau Creek. The creek runs through the central area of the farm ...
Fertiliser-coating technology to improve the efficiency of copper uptake in pastures
(Fertilizer and Lime Research Centre, Massey University, 2018)
Current practice for trace element (TE) application is to admix granular trace elements in with macro-elemental fertilisers. Although the correct rate of trace elements per hectare can be applied, the distribution of the ...
Can a winter-sown catch crop reduce nitrate leaching losses after winter forage grazing?
(Fertilizer and Lime Research Centre, 2016)
Direct grazing of winter forage crops to feed non-lactating, pregnant dairy cows prior to calving is a common management practice in the New Zealand South Island. However, the high crop yields per hectare grazed, combined ...
The effect of optimum vs deficit irrigation on plant nitrogen uptake and nitrate leaching loss from soil
(Fertilizer and Lime Research Centre, Massey University, 2016)
Nitrate (NO₃⁻) leaching, associated with urine nitrogen (N) deposition during grazing is recognised as a significant environmental problem. In this study it was hypothesised that optimum irrigation could increase plant ...
15N and 18O values of soil emitted N2O from a New Zealand pasture amended with lactose-depleted dairy factory effluent and urea - preliminary results
The study presents some preliminary data of the influence of LD-DFE on the 18O and 15N values of N2O from a New Zealand pasture soil.
Relationship between microbial community properties and nitrogen mineralisation in soils after amendment with two forms of nitrogen
Microbial diversity in soils is considered important for maintaining sustainability of agricultural production systems. However, the links between microbial diversity and ecosystem processes are not well understood. This ...
Improved nitrogen management with eco-n nitrification inhibitor : an example of "growing for good"
(New Zealand Large Herds Association, 2005-04)
The recent report by the New Zealand Parliamentary Commissioner for the Environment, called "Growing for Good", highlighted the adverse impacts that nitrate leaching can have on water quality. It called for a 'redesigning ...
The effect of DCD on nitrogen losses from sheep urine patches applied to lysimeters in autumn
(New Zealand Grassland Association, 2010)
The intensification of modern pastoral agriculture has increased the risk of environmental degradation. The use of nitrification inhibitor technology has been shown to reduce nitrate (NO₃ ⁻) leaching losses and nitrous ...
