Losses of nitrogen from the soil/plant system not only reduce soil fertility and plant yield but
can also create adverse impacts on the environment. Ammonia emissions into the …

Ruminants excrete as much as 70–95% of the nitrogen (N) they consume. The urine patch is
the conduit through which much of this N is recycled in grazed pasture systems. This chapter …

Most studies on plant nutrition tend to focus on the topsoil (plough layer) and frequently
neglect subsoil processes. However, cereal roots can potentially acquire nutrients including …

Climate change presents a range of challenges for animal agriculture in Australia. Livestock
production will be affected by changes in temperature and water availability through impacts …

Purpose Climate change is arguably the biggest environmental challenge facing humanity
today. Livestock production systems are a major source of greenhouse gases that contribute …

Core Ideas Soil solution sampling is essential to better understand water and solute
movement in soils. A review of different types of soil solution samplers is provided in this …

Nitrous oxide (N2O) is a potent greenhouse gas, and nitrate () is a water contaminant. In
grazed grassland, the major source of both leaching and N2O emissions is nitrogen (N) …

Biochar and nitrification inhibitors are increasingly being proposed as amendments to
improve nitrogen use efficiency (NUE). However, their effects on soil denitrification and the …

Purpose The oxidation of ammonium (NH 4+) to nitrate (NO 3−) in the soil is an important
biogeochemical process, which has major environmental implications as it can contribute to …

Background and aims Nitrification is the first step in several pathways that lead to losses of
nitrogen from agricultural systems. Biological nitrification inhibition (BNI) refers to the ability …
