Rangeland Improvement On Granitic Soils In Uruguay, D F. Risso, D A. Moron

IGC Proceedings (1977-2023)

Granitic soils comprise more than 15% of productive land of the country, Soils are variable, all being deficient in nitrogen and phosphorus, having a moderately low pH, more than 40% being shallow with low levels of organic matter. Livestock production is predominantly developed on range with moderate yield and ample variations (avg. DM/ha/year=3.l t; c.v.=27.6%; winter yield=l2%), Research conducted to improve this situation, evaluated: 1) range P fertilisation during 5 years, which resulted in a small (but significant) yield increase and improved P concentration of forage. 2) P fertilisation and interseeding of legumes through different methods. Largest differences were due …

Use Of Dryland Forage Plants For Improving Semi-Arid And Hawkweed-Affected Land In New Zealand, B J. Wills, J S. Sheppard, J.S C. Begg

IGC Proceedings (1977-2023)

mi-arid climatic conditions affect large areas of New Zealand's South Island east coast and inland basins. A significant area - some 6 million ha - is affected by, or is at risk from, invasion by hawkweeds, mainly Hieracium pilose/la. This plant, along with rabbits, is severely affecting the viability of extensive pastoral grassland farming in New Zealand. Soil erosion, in particular associated with frost heave and wind, is notable in areas associated with both a semi-arid climate and high densities of hawkweeds. The use of dryland pasture plants selected for drought tolerance, frost tolerance and ability to grow under low …

Small-Grain Forage For Winter Pastures, D J. Undersander, D P. Hutchenson

IGC Proceedings (1977-2023)

The paper summarises 2 studies comparing wheal (Triticum aestivum), barley (Horderim vulgare), rye (Triticale secale), and triticale (x Triticoseca/e) for fornge production and animal performance. Wheat, rye and triticale were planted in 10, 20 and 30 cm row spacings and grown over 2 winters in South Carolina. Porage yield from early­October plantings ranged from 2961 to 5000 kg/ha in 1986-87 and from l012 to 3400 kg/ha in 1987-88. Porage yield was highest from rye, most of the forage growth occurring in autumn. Wheat produced forage growth most uniformly throughout autumn and spring. In the …

Effects Of Lime And Fertilizer On The Establishment Of White Clover In The Falkland Islands, J A. Kerr, Rosie Poultney

IGC Proceedings (1977-2023)

White clover (Trifolium repens L.)-based pastures could improve low pasture and animal production in the Falkland Islands. However, establishment is difficult and expensive. Effects of lime and fertilisers containing nitrogen (N), phosphorus (P) and potassium (K) on white clover dry matter yield and root nodulation were experimentally assessed between 1986-88. Lime at 1 t/ha and 30 kg/ha P as triple superphosphate, separately improved clover yield. Nodulation was improved only by lime. Neither N nor K fertilisers affected on white clover establishment yields,

Winter Grazing Rough Fescue Grasslands With And Without Preconditioning On Annual Pasture, W D. Willms, L M. Rode, B S. Freeze

IGC Proceedings (1977-2023)

Winter grazing of the fescue prairie is desirable to reduce the cost of feeding preserved forages and to conserving the native prairie. Rough fescue (Festuca campestris Rydb,), the dominant and most productive forage species in the foothills region, is highly sensitive to summer grazing but tolerates grazing while dormant. Since the forage quality declines after senescence, and the energy requirements increase in winter, this study was made to determine the feasibility of winter gmzing pregnant Hereford cows with and without preconditioning on annual pasture. The study, replicated over a 4-year period {n=4), used a 2x2 factorial design representing native …

Interaction Of Drill Type And Herbicide On Pasture Establishment In Semi-Arid Environments, W L. Lowther, R F. Horrell, P D. Johnstone, K D. Trainor

IGC Proceedings (1977-2023)

Results are presented from an overdrilling experiment comparing a conventional triple-disc drill with an' experimental single-pass strip­seeder drill designed to remove competiting vegetation mechanically; Herbicide application markedly increased herbage mass of sown species in the triple-disc treatments. ,However, herbage mass was. higher from the strip-seeder drill than the .triple-disc in both ihe' nbsence and presence of herbicide. The results indicate the potential of the strip-seeder drill technology for cost-effective establishment of pasture species in difficult environments.

Developing Eastern Gamagrass On A Conserved Forage, John A. Dickerson, Paul R. Salon

IGC Proceedings (1977-2023)

Bastern gamagrass (Tripsacum dactyloides L.) is highly regarded as a native forage resource in the prairie region of North America. Recent discovery of a gynomonoecious plant in Kansas has raised expectations that efficient seed production will be possible with the species. A possible use for eastern gamagrass is as a perennial haylage crop for dairy farms, replacing erosion-prone silage corn. Compared with corn silage, eastern gamagrass forage has higher crude protein, slightly lower energy, and higher neutral detergent fibre and acid detergent fibre. Breeding work is underway to develop hardy, high volume forage-producing strains with good seed production capability. …

Rangelands In Dry Mountain Areas, T Boyadgiev

IGC Proceedings (1977-2023)

The extent and characteristics of temperate and mountainous climatic zones, steeply dissected and mountainous areas, permanent meadows and pasture lands, and the trend of land use evolution and aspects of land degradation are presented and discussed. The rangelands improvement strategy in Bulgaria is based on mineral fertilisation of mountainous grasslands leading to an increase in production of dry material, protein, phosphorus and cereals, This reduces sheet erosion. Overgrazing and prolonged dry periods, causing a decrease in the number of species, are also discussed, Measures to improve grassland practices are proposed.

Improvement Strategies In Winter Cold Temperate Rangeland Ecosystems With Particular Reference To Extensive Grazing Lands Of Iran, A Koocheki

IGC Proceedings (1977-2023)

Traditional land use systems in Iran have been divided between crop production and livestock grazing. Grazing land management in most parts is based on pastoral nomadism which operates between plains as winter grazing lands and mountains as summer grazing lands. Mountainous areas are an important source of food and feed production for nomads and their herds. In Iran two main ranges of mountains, Elburz and Zagros, are the summer territory of nomadic pastoralists. At present 1.5% of total population of the country are nomads. They contribute as much as 27% of value added in the animal industry of the country. …

Winter Cold Temperate Rangelands: Improvement Strategies For Intensive Rangeland Ecosystems, B E. Allan, D Scott

IGC Proceedings (1977-2023)

Transfer of developed grassland technologies to rangelands is discussed in terms of environmental gradients and the options and constraints they impose. Winier feed limitation can be overcome through conserved feeds and various in situ systems involving special purpose pastures and feed banks. General animal nutrition can be improved through intensive development, low input systems, better control of range utilisation and, where appropriate, correction of mineral deficiencies. The emphasis in seeking quick and easy solutions to rangeland management problems is questioned, A more informed, environmentally sound and sustainable approach to rangeland fanning atlitudes and management is proposed. A stepwise process to …

Topography And Wildfire Jointly Mediate Postfire Ecosystem Multifunctionality In A Chinese Boreal Forest, Jianjian Kong, Zifan Ding, Wenhua Cai, Jiaxing Zu, Bo Liu, Jian Yang

Earth and Environmental Sciences Faculty Publications

Both topography and wildfire can exert significant influences on ecosystem processes and functions during boreal forest successions. However, their impacts on ecosystem multifunctionality (EMF) remain unclear. A mega-fire burned an area of 8700 hectares in the Great Xing’an Mountains in 2000, creating a wide range of fire severity levels across various topographic positions. This provided a unique opportunity to explore the impacts of mixed-severity fire disturbance in boreal forests. We evaluated the effect pathways of wildfire and topography on aboveground multifunctionality (AEMF), soil multifunctionality (SEMF), and overall multifunctionality (OEMF). We found that high-severity burning resulted in lower AEMF, SEMF, and …
