Effects of herbage mass and herbage quality on spatially heterogeneous grazing by cattle in a bahia grass ( Paspalum notatum ) pasture
Small-scale patches (locations of 50 cm × 50 cm at a feeding station level) in a bahia grass ( Paspalum notatum ) pasture under cattle grazing were investigated in terms of herbage mass, quality and utilisation during a grazing season (May–November), to characterise the quantityquality relationship of patches and relate this to spatially heterogeneous grazing by animals. Nitrogen concentration ...
متن کاملInfluence of livestock grazing on C sequestration in semi-arid mixed-grass and short-grass rangelands.
We evaluated the effects of livestock grazing on C content of the plant-soil system (to 60 cm) of two semi-arid grasslands: a mixed-grass prairie (grazed 12 years), and a short-grass steppe (grazed 56 years). Grazing treatments included season-long grazing at heavy and light stocking rates, and non-grazed exclosures. Significantly higher soil C (0-30cm) was measured in grazed pastures compared ...
متن کاملLivestock and Vegetation Responses to Stocking Rate and Grazing System
INTRODUCTION Vegetation and livestock responses from a 25 year (1982-2006) grazing system and stocking rate study in the northern mixed-grass prairie at the USDA-Agricultural Research Service, High Plains Grasslands Research Station near Cheyenne, Wyoming are presented here. This study was longest known grazing system X stocking rate study in North America and was one of the few studies to use ...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Mixed Grazing Systems Benefit both Upland Biodiversity and Livestock Production
BACKGROUND With world food demand expected to double by 2050, identifying farming systems that benefit both agricultural production and biodiversity is a fundamentally important challenge for the 21(st) century, but this has to be achieved in a sustainable way. Livestock grazing management directly influences both economic outputs and biodiversity on upland farms while contributing to potential...
