Dryland wheat (Triticum aestivum L.) and grain sorghum (Sorghum bicolor (L.) Moench) are often grown using a wheat–sorghum-fallow (WSF) crop rotation on the semiarid North American Great Plains. Precipitation stored during fallow as soil water is crucial to the success of the WSF rotation. Stubble mulch-tillage (SM) and no-tillage (NT) residue management practices reduce evaporation, but the sp...

The Remount Depot of Baboogur is situated iu the Meerut district on the Hapui'-Garmuktasur road, it is about five miles from the town of Hapur, and derives its name from the village of Baboogur close b)T ; it lies between two streams, the Kalanuddee and Chooea, and the ground on which it stands is elevated but flat, and the soil consists of a mixture of sand and clav, through which the rain wat...

Jurisdictions that are contemplating the development of 3D Cadastres cannot afford to ignore the marine environment. Apart from its extreme importance as a resource, the use of the marine environment is volumetric by nature and involves the exercising of rights to the surface, water column, seabed, and subsoil. This paper proposes a 3D marine cadastre model that can be used to support effective...

The formation of successive fronts in contaminated groundwater plumes by subsoil bacterial action is a commonly accepted feature of their propagation, but it is not obviously clear from a mathematical standpoint quite how such fronts are formed or propagate. In this paper we show that these can be explained by combining classical reaction-diffusion theory involving just two reactants (oxidant a...

Most lowland-stream drainage-basins have a high population density and the landuse is very intensive. The permeable subsoil acts as an integrating medium, thus providing a widespread dispersal of leached nutrients and transmission of watertable lowering. This leads to desiccation and eutrophication of stream ecosystems. For providing suggestions with respect to cost-effective and sustainable sp...

Siting the nuclear cemetery in Zarra would compromise the safety of the Valencians, said Juan Cotino, third vicepresident of Valencia's regional government earlier, in a reversal of the initially mild opposition to the ATC. Zarra could not satisfy the safety requirements for such a sensitive installation, he says. Most of the subsoil in the area ia a combination of clay and loam and could be ge...
