“…The necessity for two passes over the area to be renovated, one for herbicide application, the other for fertilizer, compares less favorably with an alternative system that involves a single application of an all-granular mixture of dalapon, seed and fertilizer (5). However, on some pastures in Ontario grass cover and bare soil constitute 18 and 247o, respectively, of the surface (3).…”

“…However, on some pastures in Ontario grass cover and bare soil constitute 18 and 247o, respectively, of the surface (3). Under these circumstances an interaction between trefoil and dalapon and also phosphate fertilizer can occur, with detrimental effects on trefoil establishment (5). Because of its almost immediate and complete inactivation on contact with the soil, paraquat would not take part in such an interaction ( 1).…”

Twelve introducdons of common birdsfoot trefoil (L. corniculatus L.) obtained from the USA, Canada and the USSR were classified and compared with SlOO white and Essex red clovers when grown as spaced single plants and as spaced aggregate clumps on a lowland site at Auchincruive during 1968-69. Semi-erect and lowgrowing forms, early and late-flowering types were recorded. In terms of DM yield, the Rnssian variety Morshansk and its Canadian descendant Leo were most promising, the former outyielding both clovers over the experimental period.Two sward experiments were conducted at an upland site in south Ayrshire during 1967-8 on the effect of variations of renovation treatment and fertilizer application on the establishment and production of surface-sown trefoils. The USA variety Empire behaved simflarly to white clover in that it established and yielded satisfactory under all renovation treatments. A marked yield response to K application and a depression caused by fertilizer N were obtained in the second experiment The trefoil varieties Leo and Empire were as productive as SlOO white clover. Legume establishment was notably more satisfactory after spring sowing.Tbese results suggest that common birdsfoot trefoil bas potential value as MI alternative to wbite clover on dry soils of low fertility in Scotland wbere grazing pressure is traditionally not very severe.

In concluding the 1968 Symposium on hill land productivity (56), which has been taken as the starting point for this survey, the late Dr William Davies requested that someone prepare a blueprint for the overall development of hill lands and, more specifically, a scheme for agriculture which should include the full integration ot known facts into whole viable systems of husbandry. Since then, Walsh and Lee (111) have proposed a systems strategy for marginal land based on the concept of integrating oflF-farm feed energy with hill rough grazings, while Eadie (31, 32, 33) has proposed a 'two-pasture' year-round grazing system for sheep. The former scheme requires the provision of large areas of better quality land for conservation of herbage, or the buying of considerable quantities of feed which may not be economically feasible in all circumstances in hill areas of Great Britain. The 'two-pasture' system was designed to overcome the ecological deficiencies of traditional systems (24, 25, 30) and it has been shown to succeed in two highly contrasting environments (34, 35). A similar kind of approach is currently being tried in other areas (53, 97, 108).The most important single factor which influences animal output from the hills is nutrition and, although it is more critical prior to mating (50), iri late pregnancy (101) and during lactation (89), it needs to be improved throughout the year if output is to be increased. The key to an improved nutrition cycle for the grazing animal lies in pasture improvement.The development of successful whole-farm systems of hill sheep farming which depend on pasture improvement justifies a review of the present state of techniques for improvement and the identification of gaps in our knowledge.In addition to the above considerations:1. There is an increased awareness of the pressures of population growth on food supplies, coupled with the annual loss of approximately 20,000 hectares of good quality arable land. Wider discussion on the national needs for the improvement of hill-land use (1, 7, 52, 84) and of the particular needs in Scotland, with the largest proportion of hill land in Britain (103), has stimulated renewed interest in this subject.2. The impact of the world energy crisis on thoughts about the energy budgets of agriculture (17, 104) has indicated new grounds for supporting meat production from the hills and uplands (105). 3. The world meat shortage emphasises the importance of livestock. Although the hills produce only 7% of the total monetary agricultural output in the United Kingdom, they contribute 30% of the store sheep and 15% of the store cattle. Cunningham and Ashton (26) have recently calculated that at least 0*5 million hectares of good quality lowland would be needed to produce this output. Even if this land was available, the capital cost of preparing it for intensive livestock rearing would be immense. 4. There has been increased interest in recent years in the development of improved methods for assessing the economics of farming systems (51, 69, 70) a...
