Roles Of Clovers In Southeast U.S.A Pastures, G D. Lacefield, D M. Ball, J C. Henning, M Rasnake
IGC Proceedings (1977-2023)
Grasses dominate pastures in the Southeast U.S.A.; research and farmer experience have shown that the addition of legumes to grass dominant pastures can improve environmental, agronomic and animal parameters. Legumes grown in mixtures with grasses can increase yield, improve forage quality and animal performance, convert atmospheric nitrogen into a form useable by plants, extend the grazing season, and offset certain animal disorders. As livestock producers continue to strive for more sustainable feed production and utilization programs with greater emphasis on grazing, legumes will play an even greater role in Southeast U.S.A. agriculture.

Sustainable Grazing Systems- A Program To Develop And Deliver Improved Temperate Pastures In Australia, W K. Mason, G Kay, G Lodge
IGC Proceedings (1977-2023)
The Sustainable Grazing Systems Program aims to combine the efforts of producers, researchers and extension agents into a focused partnership to develop, manage and implement grazing systems that are more profitable and more sustainable. Rather than the traditional approach of undertaking the research and then developing extension packages for livestock producers, this Program has set up a network with producers, researchers and extension agents to collectively develop and test improved systems. The process is described as colearning. Compared with more traditional approaches, producer input is greatly increased as the role of researchers and extension agents is modified, but not decreased. …

Land Evaluation For Sustainable Land Use By Remote Sensing And Gis Case Study: Assessment Of Soil Erosion In Pakistan, Y Yamamoto, S Uchida, T Suyama, A Shoji
IGC Proceedings (1977-2023)
In the northern part of Punjab in Pakistan, severe soil erosion has caused land degradation and has disturbed sustainable land use systems. Since much of this erosion has been marked near rivers, watersheds and topography are considered to be related to soil erosion. We applied the Geographic Information System (GIS) and Remote Sensing to the assessment of an erodible area. GIS is very useful for conducting spatial data analysis using map data. Remotely sensed data provides the information about land surfaces. In this study, the distance from the river, weighted by the slope estimated by GIS, and the standard deviations …

The Effect Of Crop Residues On Cattle Productivity Wihtin Agropastoral Production Systems In Southern Mali, S.J L.E Leloup, L 'T Mannetje
IGC Proceedings (1977-2023)
The effect of seasonal diet on cattle productivity was studied in a village in southern Mali. A comparison of measured and simulated liveweight changes of cattle proved that crop residue consumption during the dry season has become indispensable for animal production. Correspondingly, maximum livestock numbers to be fed during the dry season appeared to be directed by crop residue availability. Apparently crop residue availability determines cattle productivity in this village. This is likely to be the case in most of southern Mali where the importance of rangelands’ perennial grasses is decreasing.

Grazing Impacts On The Production Stability Of Fescue Prairie, W D. Willms, J F. Dormaar, J R. King
IGC Proceedings (1977-2023)
The fescue prairie in southwestern Alberta is highly productive but susceptible to grazing during the growing season. This study examined how production stability is affected by grazing impact. It was initiated in 1949 using four fixed stocking rates (1.2, 1.6, 2.4, 4.8 animal-unitmonths ha-1). Forage and livestock production were estimated over 4 or 15 years, respectively. The coefficient of variation (CV) for either primary or secondary production was constant over all rates except for the very heavily stocked paddock. Forage production, and therefore livestock production, in that paddock was dependent on precipitation during the growing season. Heavy grazing pressure resulted …
