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 ...

The quantification of spray mass has historically been accomplished by means of fluorescent dyes and various string and ground samplers to capture the dye-laden spray. However, these methods are typically not used in close ...

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 ...
