Rangelands cover approximately 85% of Kenya’s land mass and is a major resource for livestock farming with a considerable potential to mitigate climate change, yet these lands are stressed differently by various management. Our study aimed at determining the influence of grazing management systems (rotational, continuous and ungrazed) on soil organic carbon stocks in Yoani ranch located in the ...
Resumen. Este artículo describe el Modelo de Realización de Metamorfosis. El propósito principal de este marco es proporcionar la base conceptual necesaria para el establecimiento de vínculos persistentes y controlables entre la especificación de los requisitos funcionales del sistema (expresado como un Modelo de Casos de Uso) y el producto de su análisis (representado a través de un Modelo de ...
Cover crops are important for soil conservation efforts but can compete with cash limited water in dryland agricultural systems. Grazing cover may provide additional income to improve the profitability of cropped systems, effect grazing on health remains poorly understood semi-arid regions. We conducted on-farm research examine short-term effects grazed and un-grazed spring-planted compared ful...
Three commercial broiler houses were (12.2 × 152.4 m) were monitored for 3 consecutive flocks. The houses were treated with Poultry Litter Treatment (PLT), 24 h before bird placement at the rate of 24.4 kg /100 m2. PLT was applied in the central brooding area for all 3 flocks and represented the treated (TR) area while the rest of the house remained untreated (UN). Litter samples were obtained ...
the effect of planted saltbush (atriplex lentiformis) on edaphic factors in grazed and ungrazed area
re-vegetation of bare soil is believed to increase, or at least maintain the organic matter levels of soil. the aim of this study was to investigate the soil characteristics changes, nutrient pool sizes and their availability under mid canopy, and canopy gap positions of saltbush in an area re-vegetated with atriplex lentiformis. some of the physical and chemical soil characteristics (the parti...
Tree and shrub abundance has increased in many grasslands causing changes in ecosystem carbon and nitrogen pools that are related to patterns of woody plant distribution. However, with regard to spatial patterns of shrub proliferation, little is known about how they are influenced by grazing or the extent to which they are influenced by intraspecific interactions. We addressed these questions b...
Runoff from a cow-calf pasture in eastern Nebraska was monitored for total coliforms (TC), fecal coliforms (FC), and fecal streptococci (FS) during 1976, 1977, and 1978. Bacteriological counts in runoff from both grazed and ungrazed areas generally exceeded recommended water quality standards. The FC group was the best indicator group of the impact of grazing. Rainfall runoff from the grazed ar...
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 ...
Species which were grazed by livestock and wildlife in range sites and the portion taken by each animal were the subject of this study. Two sites occupied with Scariola orientalis (Boiss.) Sojak and Artemisia sieberi Besser and another with Aellenia subaphyla (C.A.Mey.)Aellen and Artemisia sieberi were selected for the study. These sites were already established by Yazd Research Center for Agri...
