X-ray fluorescence spectrometry is widely accepted as a highly versatile and potentially accurate method of instrumental analysis. The occurrence of sulphur deficiencies in many areas has led to increased research on ...

The growing concentration of population in metropolitan centres commonly results in the spread of urban areas onto land with a high value for food production. This aspect of urban growth represents poor allocation of ...

It is commonly assumed in the application of many models of catchment behaviour that catchment rainfall is uniformly distributed over a catchment. This study examines the effects of non-uniform spatially distributed rainfall ...

The literature on the pathogens Septoria tritici and Septoria nodorum, and the wheat diseases they cause has been reviewed, including methods of disease assessment and some aspects of fungicide application and mode of ...

The primary aim of this research is to study in detail the soil pattern and erosion characteristics of a small representative catchment in the Wither Hills, and to determine the interrelationship between soil properties, ...

The processed pea industry has grown rapidly in New Zealand over the last few years and prospects for further growth look reasonably bright. In the past the main production area for processed peas has been Hawkes Bay. With ...

New Zealand has a total area of 66.4 million acres, of which 44 million are classified as occupied farm land. More than 40 per cent of this latter area is held under leasehold tenure. The Crown is the landlord of 14.9 ...

A number of morphological, floral, rhizome, root and herbage characteristics were studied in order to describe genetic variation and environmental responses in T. ambiguum. From each of six lines, 30 genotypes were clonally ...

Computer programmes were developed for processing data from grid, direct, and random stadia field contouring systems. The three systems were evaluated for their use in providing contour plans for bordered strip irrigation ...

Techniques were devised to map and describe the extremely variable soil pattern associated with moraines in the East Lake Pukaki Region. In such cases there arises a conflict between cost, utility, scale of mapping and ...
