Effect of climate/soil moisture content on aluminium toxicity and carbon stocks of two high country soils under glasshouse conditions
(Lincoln University, 2015)
Aluminium (Al) toxicity is a key factor limiting pasture production in the high country of New Zealand. Many high country soils are acidic, with a pH less than 5.5. Low soil pH makes Al soluble, leading to high concentations ...
Understanding the potential for nitrate attenuation from paddock to stream using dual nitrate isotopes : A thesis submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy at Lincoln University
(Lincoln University, 2019)
Ruminant urine deposition can result in nitrate (NO₃⁻) leaching from soil to groundwater under agricultural systems. Nitrous oxide (N₂O) emissions from ruminant urine patches are also a major concern as N₂O is a potent ...
