Optical sensors for variable rate nitrogen application in dairy pastures
(New Zealand Grassland Association, 2017)
Reducing the amount of nitrogen (N) fertiliser applied to dairy pastures down to agronomically optimised levels would have positive economic and environmental results. The ability of commercially available optical sensors ...
Soil inorganic nitrogen in spatially distinct areas within a commercial dairy farm in Canterbury, New Zealand
(New Zealand Grassland Association, 2017)
For precision nitrogen (N) fertilisation of grazed dairy paddocks, soil N distribution needs to be quantified. It is expected that farm infrastructure will affect inorganic-N distribution due to its influence on cow grazing ...
