Sustainable restoration of mine sites
(Lincoln University, 2009)
A sustainable approach to restoration of the post-mining landscape involves creating conditions where a viable growth medium can be established with the minimal amount of fertiliser inputs over a period of time. Ideally, ...
The dynamic interplay of mechanisms governing infiltration into structured and layered soil columns
(Lincoln University, 2009)
Worldwide there is considerable concern over the effects of human activities on the quantity and quality of freshwater. Measurement of infiltration behaviour will be important for improving freshwater management. This study ...
Grazing management of subterranean clover (Trifolium subterraneum L.) in South Island (New Zealand)
(Lincoln University, 2009)
This study consisted of two sheep grazed dryland pasture experiments. Experiment l compared sheep production from 3-year-old cocksfoot based pastures grown in combination with white, Caucasian, subterranean or balansa ...
Sorption, degradation and transport of estrogens and estrogen sulphates in agricultural soils
(Lincoln University, 2009)
The fate and behaviour of estrogens in the environment are of concern due to the compounds’ endocrine disruption potential. Estrogens, namely 17β-estradiol (E2), estrone (E1), and estrogen sulphates, i.e. 17β-estradiol-3-sulphate ...
Fair trade coffee supply chains in the highlands of Papua New Guinea: do they give higher returns to smallholders?
(Lincoln University, 2009)
This research focussed on Fair Trade (FT) coffee supply chains in Papua New Guinea. Three research questions were asked. First, do small holders in the FT chains receive higher returns than the smallholders in the ...
The vegetative and reproductive development of balansa clover
(Lincoln University, 2009)
The vegetative and reproductive development of balansa clover (Trifolium michelianum Savi.) were quantified in relation to the environmental drivers of each phenophase in field and controlled environments. In a grazed ...
Biochemistry and genetics of carotenoid composition in potato tubers
(Lincoln University, 2009)
Potato cultivars exhibit a wide variation in skin and flesh colour due to the presence of pigments. This study established that potato cultivars differ greatly with respect to types and concentrations of carotenoids in ...
Estimating bioaccessibility, phytoavailability and phytotoxicity of contaminant arsenic in soils at former sheep dip sites
(Lincoln University, 2009)
Recognition that the bioavailability of soil As (As) is influenced by its soil dynamics has initiated research into development of more accurate, site-specific soil guideline values, departing from the assumption that the ...
Residual concentrations and persistence of the anticoagulant rodenticides brodifacoum and diphacinone in fauna
(Lincoln University, 2009)
Brodifacoum is a highly effective anticoagulant rodenticide that presents a secondary hazard to some non-target wildlife. The high acute toxicity of brodifacoum to mammals and birds, and its prolonged persistence in liver ...
Effect of irrigation on growth and nitrogen accumulation of Kabuli chickpea (Cicer arietinum L.) and narrow-leafed lupin (Lupinus angustifolius L.)
(Lincoln University, 2009)
A field experiment was conducted to examine the responses in growth, total dry matter (TDM), seed yield and nitrogen (N) accumulation of Kabuli chickpea cv. Principe and narrow-leafed lupin cv. Fest to different irrigation ...
