J. Molybdenum is the most recent addition to the list of those elements essential for plant growth. Such insignificant amounts are required to give benefit on deficient areas that results from its application are truly amazing, yet, where it is found to be necessary, application of this trace element may mean the difference between low and high pasture production. It appears that molybdenum will continue to be used in this country for numerous trials have indicated that as far as pasture production is concerned, a few ounces of molybdenum give results as good as several tons of lime in many cases. This work is an attempt to show the differences, if any, in soil structure, earthworm populations, organic matter content, mineralisation of soil nitrogen, exchangeable manganese content, and phosphate fixing power of the soil due to treatment in the field with lime and with molybdenum.

Throughout history people have recognised the importance of the narrow strip of land immediately behind the land sea interface. The build their houses, villages, towns and cities within easy reach of the sea. Access to and from the sea is highly valued and in New Zealand it has been guaranteed to the general public over most of the coastline by the retention from sale by the Crown of a strip of land approximately 20 metres wide measured from the mean high water mark. In Marlborough this 20 metre strip of land has received the unique land classification of "Local Purpose Reserve for Sounds Foreshore Purposes" and is subject to the provisions of Section 7 of the Reserves and Other Lands Disposal Act 1982 and the Reserves Act 1977. The total area is some 1,500 hectares extending along 900 kilometres of the coastline. Objectives of the Dissertation (a) To describe and analyse the legislation and management policies governing foreshore reserve. (b) To provide a document that will contribute to the development and implementation of Sound management policies for foreshore reserves in accordance with existing legislation.

The world trend is to recover costs for services and products provided by government. No longer is it a matter of what might be desirable in presenting and implementing agricultural policy – rather it is, what are the economic realities. The New Zealand Ministry of Agriculture and Fisheries (NZ MAF) was confronted by the economic reality. No longer was the farmer to be treated as if he was special. To remain a relevant organization the NZ MAF had to come out from behind the farm gate and actively identify where it could successfully compete in the market place. The facts were: • Restructure to operate as an economic unit • Reduce staff numbers • Develop a new culture • Produce to survive Three years after the introductory charges and eight months after major restricting the important lessons are: A) Develop a functional focus with clear objectives, a clear idea of where the organisation is going and how to get there B) Identify clients and tailor products/services to their needs C) Find out what is important to staff to obtain job satisfaction and develop the new culture around it That is the economic reality and now it can be argued that the tax payer won’t be expected to provide services for the benefit of a limited few. However, in the zeal for profit, there is a danger of undermining the proper role of the state as the guardian of the interests of the whole society. Will the public service that emerges from the profit making state be appropriate – is it the best way to serve the public and be a good employer?

Thirty environments resulting from the combination of five soil fertility regimes, three stocking rates and two grazing methods were imposed on multi-species mixtures overdrilled into hawkweed-dominated short tussock grassland at Lake Tekapo. Legume species dominated during the three year trial period covered by this study. The most important legume from 0 to 250 kg fertiliser ha-1 yr-1 was Russell lupin (Lupinus polyphyllus ), used here as a pasture species. The second most important species was alsike clover, followed by red and white clovers, the latter only under irrigation and high fertilisation. The most important experimental factor affecting the relative ranking of species during the experimental period was soil fertility regime; secondly, stocking rate and last, grazing methods. Introduced and resident species were significantly related to environments defined as follows: • Fescue tussocks, mouse-ear hawkweed and adventive grasses with unimproved soils and light grazing; • Russell lupin with little-amended soil conditions and moderate grazing pressure; • White clover with fully developed conditions; • Red and alsike clover with increasing grazing pressure and lower soil fertility regimes. Hieracium did not disappear as a consequence of soil improvement and grazing but appeared to be favoured by hard grazing. Tussocks within dense legume swards did not seem to play any role of importance; if the canopy was open they became more conspicuous, but always at the lower range of relative abundance. A supplementary experiment showed that in the absence of other vegetation shelter, the shelter provided by silver tussocks to shorter grasses resulted in increased relative growth rates in swards, providing that a rather sparse tussock distribution (plants 120 cm apart) was maintained. A closer tussock canopy could produce an opposite effect. Sheep grazing preferences were detected at all situations, but actual total utilisation of pasture did not present important differences between introduced species. True rejection occurred only for mouse-ear hawkweed at soil improved treatments. Tue, 01 Jan 1991 00:00:00 GMT https://hdl.handle.net/10182/8120 1991-01-01T00:00:00Z
