The effectiveness of nitrification inhibitor technology to improve the sustainability of agriculture
(NZ Institute of Primary Industry Management (NZIPIM), 2009-12)
As reported widely in the general media and also in recent editions of Primary Industry Management, there is increasing recognition of the need to improve the sustainability of New Zealand agricultural systems. Fonterra’s ...
Nutrient management on the Lincoln University dairy farm: "nutrient budgeting for efficient production"
(South Island Dairy Event (SIDE)., 2007-06)
Nutrient management plays an important role in any dairy farming system. Soil fertility
status and fertiliser inputs are key drivers of pasture and animal production, whilst fertiliser
represents a significant annual cost ...
Phosphorus exchangeability and leaching losses from two grassland soils
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2002)
Although phosphate phosphorus (P) is strongly sorbed in many soils, it may be quickly transported through the soil by preferential flow. Under flood irrigation, preferential flow is especially pronounced and associated ...
Using nitrogen : what is best practice?
(South Island Dairy Event (SIDE), 2005-06)
Feed shortages occur in spring because the rate of pasture growth is below the cow
demand. Spring pasture growth rate is slow in the South Island because the soil
temperature is low and the rate of nitrogen (N) supply from ...
Improved nitrogen management with eco-n nitrification inhibitor : an example of "growing for good"
(New Zealand Large Herds Association, 2005-04)
The recent report by the New Zealand Parliamentary Commissioner for the
Environment, called "Growing for Good", highlighted the adverse impacts that
nitrate leaching can have on water quality. It called for a 'redesigning ...
Reducing nitrate leaching losses from a Taupo pumice soil using a nitrification inhibitor eco-n
(New Zealand Grassland Association, 2007-11)
The decline in water quality in Lake Taupo has been attributed to nitrogen (N) leaching from surrounding land areas. Pastoral agriculture has been identified as a significant contributor to this N transfer to the lake ...
Fungal inoculum properties : Extracellular enzyme expression and pentachlorophenol removal by New Zealand Trametes species in contaminated field soils
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2007)
This study was conducted to improve the ability of indigenous New Zealand white-rot fungi to remove pentachlorophenol (PCP) from contaminated field soil. The effects of different bioaugmentation conditions on PCP removal ...
Fungal inoculum properties : Extracellular enzyme expression and pentachlorophenol removal in highly contaminated field soils
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2007)
This study was conducted to improve the pentachlorophenol (PCP) bioremediation ability of white-rot fungi in highly contaminated field soils by manipulating bioaugmentation variables. These were the dry weight percentage ...
Seasonal fluctuations in phosphorus loss by leaching from a grassland soil
(Soil Science Society of America, 2004)
Phosphorus losses from soils have been reported to impair the water quality, resulting in deaths of fish and other marine animals, and can harm human health. The objective of this study was to determine the seasonal ...
Clean and green with 'eco-n'
(South Island Dairy Event (SIDE)., 2004-06)
Lincoln University and Ravensdown Fertiliser Co-operative have developed a new soil
treatment technology, called 'eco-n' technology, that can reduce the environmental impacts of dairy farming and at the same time help ...
