Rangeland management and animal production sustainability under arid and semi arid conditions: Egypt overview

Livestock fodder needs in nearly all developing countries now exceed the sustainable yield of rangelands and other forage resources. In Africa, overgrazing has reduced range productivity virtually everywhere. It is important to provide animals with adequate nutrition to ensure the high productive and reproductive performance. Meanwhile, it is necessary to avoid the deterioration of the pasturel...

Modelling evaporation and drift losses in irrigation with medium size impact sprinklers under semi-arid conditions

A proper understanding of factors affecting evaporation and drift losses in sprinkle irrigation is important for developing water conservation strategies. For estimating drift and evaporation losses during the set sprinkler irrigation event, several outdoor single-sprinkler and block irrigation tests have been conducted. Various sprinkler±nozzle±riser height combinations were used and the varia...

Improving soil surface properties: a driving force for conservation tillage under semi-arid conditions

The effect of long term conservation tillage (CT) application on soil organic carbon (SOC) concentration, and on stratification ratios (SR) of SOC, soluble organic carbon (SOCs), microbial biomass carbon (MBC) and protease activity (PA) has been studied. The SR was established dividing values of these variables at 0-5 cm depth by values at 10-25 cm depth. The results were compared with those ob...

Cropping systems alter weed seed banks in Pacific Northwest semi-arid wheat region

Arable land weed seed banks are dynamic and reflect cropping history, current management, and environment. Changes in crop rotation and tillage system can alter weed seed density and species composition. In the semi-arid region of the Pacific Northwest, USA, no-till spring cropping is being studied as an alternative to the traditional winter wheat (Triticum aestivum L.)/dust-mulch fallow (WWF) ...
