The interactive effects of nitrogen fertiliser and animal urine on nitrogen efficiency and losses in New Zealand dairy farming systems
(Lincoln University, 2013)
The loss of nitrogen (N) through nitrate (NO₃⁻) leaching and nitrous oxide (N₂O) emissions from pastoral dairy systems is one of the largest challenges facing the New Zealand agricultural industry. Nitrate leaching ...
The fate of nitrogen in an animal urine patch as affected by urine nitrogen loading rate and the nitrification inhibitor dicyandiamide
(Lincoln University, 2014)
The animal urine patch is the main source of nitrogen (N) loss from agricultural grazed pasture systems. Losses include emissions of nitrous oxide (N₂O), a potent greenhouse gas, and leaching of nitrate (NO3-) into ...
Phosphorus legacy: role of long-term soil phosphorus accumulation in the sustainable management of intensive agroecosystems
(Lincoln University, 2017-08-02)
Phosphorus (P) is an essential nutrient for all organisms. Phosphate rock is primarily utilised for the manufacture of P fertilisers, and is a finite resource. Most agricultural lands worldwide present low levels of available ...
Effects of lime, phosphorus and sulphur on the establishment of Hairy Canary and Tagasaste on an acid high country soil.
(Lincoln University, 2014)
Legumes play a critical role in New Zealand high country farming systems as the sole provider of nitrogen (N) to the pasture sward through biological nitrogen fixation. N also increases the quantity and quality of pastures ...
Soil carbon sequestration
(Lincoln University. Faculty of Commerce. Kellogg Rural Leaders Programme., 2010)
This resource focuses on 'Soil Carbon Sequestration'. Is it possible to sequester carbon in
soils? How? What are the upsides to doing so? Could the carbon sequestered in soils enter the
Emissions Trading Scheme and be ...
Impact of different tree species on soil phosphorus immediately following grassland afforestation
(Sociedad Chilena de la Ciencia del Suelo (Chilean Society of Soil Science), 2016-06)
Previous studies have revealed that significant changes in soil phosphorus (P) occurred as a consequence of grassland afforestation, although when these changes occurred and the influence of different tree species remains ...
Advances in agronomic management of phytoremediation: methods and results from a 10-year study of metal-polluted soils
(PAGEPress, 2012-10-12)
Among green technologies addressed to metal pollution, phytoextraction has received increasing attention in recent years as an alternative to physical and chemical methods of decontamination. Since 1998, as part of an ...
Phosphorus response and optimum pH ranges of twelve pasture legumes grown in an acid upland New Zealand soil under glasshouse conditions
(Chilean Society of Soil Science (Sociedad Chilena de la Ciencia del Suelo), 2016-06)
Pasture legumes provide critical nitrogen inputs but fail to persist in typical acidic low P fertility upland soils. Alternative legume species for these environments are urgently sought. Twelve novel legume species were ...
Phosphorus response and efficiency of 12 novel dryland legume species on an acid high country soil
(Fertilizer and Lime Research Centre, Massey University, 2012-02)
High country soils are typically acidic and have low fertility compared with intensive high fertility low land systems. Pasture legumes commonly used in New Zealand perform poorly in these environments. The optimum soil P ...
A critical view of current state of phytotechnologies to remediate soils: Still a promising tool?
(Hindawi Publishing Corporation, 2012)
Phytotechnologies are often shown as an emerging tool to remediate contaminated soils. Research in this field has resulted in many important findings relating to plant and soil sciences. However, there have been scant ...
