Use of gypsum blocks for measurement of soil water status : A dissertation submitted in partial fulfilment of the requirements for the Diploma of Agricultural Science in the University of Canterbury [Lincoln College]
Considerable attention has been devoted to soil moisture studies by workers in agriculture, forestry, and engineering, and to a lesser extent by geographers. Methods range from age-old one of feeling a soil, to the recent neutron-scattering devices. The Gravimetric method of soil moisture …

A study of the influence of aspect on some soil properties of a Kaikoura steepland soil under a tussock grassland : A dissertation submitted in partial fulfilment of the requirements for the degree of Bachelor of Agricultural Science (Honours) in the University of Canterbury [Lincoln College]
Steepland soils tend to show more variability than soils on rolling or flat land. One of the factors responsible for some of the variation within these soils is the microclimatic changes that occur between different aspects of a hill. North - and south - facing slopes offer excellent situations in …

Studies on the aerobic bacterial flora of a New Zealand tussock grassland soil
… flora of a single New Zealand grassland soil whose characteristics are described. The 4 parts deal respectively with the characterisation of the aerobic heterotrophic bacterial flora, the activity this flora as measured by a number of different techniques, nitrification and sulphur …

Development of mechanistic energy balance models for grassland
… of grassland productivity include near-surface soil and air temperatures and plant water use. Therefore it is important to understand how grasslands partition the energy they receive into heat and vapour fluxes, and soil heat flux which regulates the underlying soil temperatures. The project …

A study of some soil fertility problems in Canterbury
… of the early work associated with improvement of soil fertility was confined to the relatively productive plains and other readily accessible regions. That these areas have been highly developed agriculturally may be seen by the capability of some of them to give maximum pasture productions in …

The effect of winter grazing and a nitrification inhibitor on nitrous oxide emissions and denitrification in a stony soil
… of New Zealand. Such intensive grazing on wet soil increases the risk of denitrification and the production of the powerful greenhouse gas, nitrous oxide (N₂O). However, at the beginning of this research project, no information was available on denitrification and N₂O emission from forage crops …

A management study of irrigation farming in the Ashburton-Lyndhurst scheme of Mid-Canterbury
… is used to raise the productive capacity of the soil, where soil moisture is a limiting factor. Many irrigation areas can not achieve any production without the supplementation of soil moisture, while others employ irrigation as a profitable means of boosting the normal production level. In 1935, …
