Tunisia: Reform of irrigation policy and water conservation
An arid country with limited water resources, Tunisia depends heavily on irrigated agriculture. The sector contributes 30-40% of the value of agricultural production, and is highly important in some regions. However, abstraction for irrigation accounts for 83% of the available water resources, competing with other uses. To conserve water resources and encourage demand management in the irrigation ...

Application of initial value method in the static analysis of laterised concrete cylindrical shells under hydrostatic loading
In Nigeria, the prices of building materials continue to increase sharply that there is growing need to explore the possibility of utilisation of local raw materials as alternatives for farm building construction. This study investigated the performance of a laterised cylindrical shell under hydrostatic loading. The properties of laterised concrete at optimum mix proportion were adopted in ...

Selecting and applying cesium-137 conversion models to estimate soil erosion rates in cultivated fields
Received for publication April 19, 2009. The fallout radionuclide cesium-137 (137Cs) has been successfully used in soil erosion studies worldwide. However, discrepancies often exist between the erosion rates estimated using various conversion models. As a result, there is often confusion in the use of the various models and in the interpretation of the data. Therefore, the objective of this study ...

Effects of reducing dietary nitrogen on ammonia emissions from manure on the floor of a naturally ventilated free stall dairy barn at low (0–20°C) temperatures
Received for publication December 30, 2008. This study was conducted to determine the potential for reducing ammonia (NH3) emissions from manure deposited on the floor of a naturally ventilated free stall barn by mid-lactation dairy cows fed reduced or normal N diets. Two crude protein (CP) diets (178 g kg–1 [high] and 159 g kg–1 [low] dry matter ), were used. The diets were fed to 48 Holstein ...

Investigations into the possibility to compost paraffincoated packaging materials
Utilisation of biodegradable materials is indispensable for effective economic operation (Soyez, 1998). However, the requirements to be met by the application characteristics sometimes prevent use of such materials. For example, packaging materials for foodstuffs, where protection of the contents is the predominant aim, are required to display hydrophobic properties. Paraffin-coated papers have ...
