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 ...
Urine patch detection using LiDAR technology to improve nitrogen use efficiency in grazed pastures
In grazed dairy pastures, the largest N source for both nitrate (NO₃⁻) leaching and nitrous oxide (N₂O) emissions is urine-N excreted by the animals. Additional application of N on urine patches as fertilizer may increase ...
