Volatile fatty acids and methane production from browse species of Algerian arid and semi-arid areas

Chemical Composition, In Situ Degradation, And Fermentation Kinetics Of Some Browse Plant Species Collected From Algerian Arid And Semi-Arid Areas

The chemical composition and digestibility of twelve plant samples (Arthrocnemum macrostachyum, Atriplex canescens, Artemesia herba-alba, Astragalus gombo, Calobota saharae Ceratonia siliqua, Gleditsia triacanthos, Hedysarum coronarium, Medicago sativa, Ononis natrix L, Hordeum vulgare and <...

Soils of Arid and Semi-arid Areas

Simulation of the catchments hydrological processes in arid, semi-arid and semi-humid areas

Hydrological processes and their spatial distribution directly are relevant to climate, topography, geology, and land use in the watershed. Therefore, use of a model whit integrity and high performance for simulating the process in deferent watersheds is very important. In this study was assessment performance of semi-distributed SWAT model in simulating hydrology processes in three watersheds ...

Solar Radiation Estimation from Rainfall and Temperature Data in Arid and Semi-arid Climates of Iran

Precipitation and air temperature data, only, are often recorded at meteorological stations, with radiation beingmeasured at very few weather stations, especially in developing countries. Therefore there arises a need for suitablemodels to estimate solar radiation for a completion of data sets. This paper is about an evaluation of eight models foran estimation of daily solar radiation (Q) from ...

Nutritive Evaluation of Some Browse Tree Legume Foliages Native to Semi-arid Areas in Western Tanzania*

Browse tree legume leaves from Acacia spp (A. nilotica, A. tortilis, A. polyacantha), Dichrostachys sp, Flagea villosa, Piliostigma thonningii, Harrisonia sp were evaluated for nutritive potential (chemical compositions and degradability characteristics) compared to Gliricidia sepium. Effect of tannins anti-nutritive activity on digestibility was also assessed by polyethylene glycol (PEG) tanni...
