Methodologies for measuring thresholds of change from tourism impacts on New Zealand natural assets
(Lincoln University. Tourism Recreation Research and Education Centre, 2004-11)
The demand to see and the level of diverse use made of natural assets by tourists is increasing and a methodology is needed to measure change in the condition of these assets and whether or not that change is acceptable ...
Variability in yield of four grain legume species in a subhumid temperate environment. I. Yields and harvest index
(Cambridge University Press, 2004-02)
In 1998/99 and 1999/2000, field trials were conducted to try to explain why grain legume yields and harvest index are more variable than many other crops. Treatments involved varying plant populations and sowing depths and ...
Light interception and utilization of four grain legumes sown at different plant populations and depths
(Cambridge University Press, 2004-06)
Canopy development, radiation absorption and its utilization for yield was studied in four grain legume species Cicer arietinum, Lens culinaris, Lupinus angustifolius and Pisum sativum. The grain legumes were grown at ...
Nitrogen distribution in four grain legumes
(Cambridge University Press, 2004-06)
The partitioning of above ground nitrogen (N) in chickpea (Cicer arietinum), lentil (Lens culinaris), lupin (Lupinus angustifolius) and pea (Pisum sativum) at crop maturity was investigated. The plants were grown at different ...
Variability in yield of four grain legume species in a subhumid temperate environment. II. Yield components
(Cambridge University Press, 2004-02)
The effects of plant population (one-tenth of the optimum to four times the optimum populations in 1998/99 and 10–400 plants/m² in 1999/2000) and sowing depth (2, 5 and 10 cm) on yield and yield components of four grain-legumes ...
An assessment of cadmium availability in cadmium-contaminated soils using isotope exchange kinetics
(Soil Science Society of America, 2004)
There has been much research conducted to find suitable methods for the determination of available Cd in soils. In recent years, an isotope exchange kinetics (IEK) technique has been tested to describe the kinetic transfer ...
Increasing phosphate rock availability using a lupin green manure crop
(Lincoln University, 2004)
Legumes have been shown to increase the dissolution and utilisation of phosphate rock (PR) phosphorus (P) compared with non-legumes because of their acidifying effect on the rhizosphere. A promising agronomic approach for ...
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 ...
An analysis of the feasibility of using image processing to estimate the live weight of sheep
(Lincoln University. Farm and Horticultural Management Group., 2004-06)
One of the difficulties in successfully managing the supply and use of animal feed in sheep farming is in knowing the live weight of the sheep in the various mobs a farmer may be using. Most farmers make intuitive estimates ...
Small-scale spatial variability of selected soil biological properties
(Elsevier, 2004-04)
A strategy for sampling soil from intact monolith lysimeters was established based on measurements of spatial heterogeneity within the lysimeter area. This was part of an ongoing study to determine relationships between ...
