A computer model for designing of permanent gully control structures

Engineering measures of soil and water conservation are an integral part of watershed management or development, and thus they must be designed accurately and economically. Designing of various gully control structures plays a vital role in the success of any watershed development programme. Analytical designing of these structures in terms of hydrologic, hydraulic and structural stability is very important. The study...

The use of edaphic factors to map the spatial distribution of root knot nematodes in tobacco plantations

Root-knot nematodes are the most economically important group of plant parasitic nematodes. They are unevenly distributed in the soil making blanket nematicide applications uneconomic. Soil edaphic factors have been reported to be related to nematode distribution and hence can indicate nematode distribution in the soil. This study seeks to find out if the relationship of soil edaphic factors and nematode distributions...
