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 ...
Water holding characteristics of pumice fragments in New Zealand Pumice Soils : A thesis submitted in partial fulfilment of the requirements for the Degree of Master of Science at Lincoln University
(Lincoln University, 2020)
Nutrient budget models are used throughout New Zealand to monitor the movement of water and nutrients in farm systems. Currently there is limited knowledge pertaining to the water release and water holding characteristics ...
Determination of genes Involved in bacterial phosphate solubilisation
(Lincoln University, 2014)
Agricultural systems depend on continued inputs of phosphate fertiliser to maintain productivity. However, due to ever increasing global demand, the finite reserves of phosphate rock are being rapidly depleted. This is ...
The quid pro quo of dissolved organic matter biodegradability in agricultural soils: investigations of quantitative and biochemical aspects : A thesis submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy at Lincoln University
(Lincoln University, 2019)
Dissolved Organic Matter (DOM) serves as a primary source of mineralizable carbon (C), nitrogen (N), and other macroelements for plants and soil microbiota, acting as a linchpin of nutrient dynamics and energy flows through ...
Factors affecting the degradation of the nitrification inhibitor dicyandiamide in a lowland Canterbury stream
(Lincoln University, 2014)
Dicyandiamide (DCD) is an effective nitrification inhibitor and can reduce nitrate (NO₃⁻) leaching losses and nitrous oxide (N₂O) gas emissions from soil. In New Zealand DCD was primarily used on dairy farms in the aim of ...
Biological farming in New Zealand
(Lincoln University. Faculty of Commerce. Kellogg Rural Leaders Programme., 2010)
This paper discusses the principles, outcomes and benefits of
biological farming in New Zealand. New Zealand agriculture is at
present extremely reliant on petrochemical based fertiliser and
chemicals to produce ...
The effect of winter grazing and a nitrification inhibitor on nitrous oxide emissions and denitrification in a stony soil
(Lincoln University, 2015)
Intensive grazing of forage crops by dairy cows is common practice during the winter months in the Canterbury region of New Zealand. Such intensive grazing on wet soil increases the risk of denitrification and the production ...
Farming under nitrate leaching limits: ‘A case study of the effects of meeting potential nitrate leaching limits in a Canterbury dairy farming situation’
(Lincoln University. Faculty of Commerce. Kellogg Rural Leaders Programme., 2013)
This report investigates the impact that altering the farm system of Singletree Dairies in mid
Canterbury to achieve a predicted nitrogen leaching loss in Overseer of 24kgN/ha/year will have on
both the operation management ...
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 ...
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 ...
