These forests are important from both the national and regional viewpoints, as with controlled cutting they will be capable of producing a major contribution to New Zealand's requirements of high quality timber and veneers for nearly one hundred years. Their value will be further enhanced in the future, as the now limited indigenous forests in other regions are depleted, and this premium will be maintained until, and even after, such time as comparable grades can be produced in sufficient quantity from well-tended exotic forests. As a strategic reserve, should any disaster befall the exotic forests, the indigenous forests of Westland also fill a valuable role. From the regional viewpoint, these production forests will provide the raw material for a locally based industry, which is now being expanded to help give stability to a regional economy where the resources available for industrial development are limited.","PeriodicalId":261810,"journal":{"name":"Proceedings of the New Zealand Grassland Association","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1964-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134029676","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While there is much scope for development of poorer country, and while this is perhaps the glamour way of increasing production, a tremendous increase can come by raising the production on fully-developed dairy farms. By increasing the stocking rate of dairy cows, production levels can be raised almost overnight, and, while initial costs for extra stock may be high, returns in the first year often cover these costs. The only other cost is perhaps for extra fertilizer, but this too is quickly recovered. Three years' trial work at the Waimate West Demonstration Farm, in South Taranaki, illustrate the basic principle : \"More cows +more fertilizer = more butterfat = more cash\". This principle can be applied equally well to sheep and beef cattle properties. The Manaia farm at Waimate covers 90 acres of Egmont black loam, a freedraining derivative of Egmont andesitic ash. Rainfall varies, from 45 to 50 in. per year with dry periods common in summer and early autumn. Whole milk is produced for cheese factory supply.","PeriodicalId":261810,"journal":{"name":"Proceedings of the New Zealand Grassland Association","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1964-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115868082","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many plant constituents contribute to this policy but only one group, the carbohydrates, will be considered here. At present probably the only reliable and meaningful method of assessing the relative nutritive value of different pastures is by comparing actual animal production on the pastures growing under identical conditions. Such a method is, of course, unsuitable for the plant breeder during the early stages of a plant breeding programme when he needs to select for quality from a large number of plant progenies. For this reason, it is desirable that quality be defined in more specific terms so that relatively simple tests for it can be devised. Work aimed at such a definition should, of course, be based on material from pastures whose animal potential is being measured at the same time. For this reason, work at Plant Chemistry Division on the possible role of the carbohydrate constituents in contributing to nutritive value has been based largely on material from single variety ryegrass pastures on which growth rate in sheep has been the index of animal production. The present account of how the plant carbohydrate composition of pasture can influence pasture quality will be illustrated with results obtained from these trials.","PeriodicalId":261810,"journal":{"name":"Proceedings of the New Zealand Grassland Association","volume":"2016 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1964-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127502590","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Also it is more vulnerable to the weather.
