Effect of the soil moisture variation on apparent resistivity profiles and a method of correction
In order to get an apparent resistivity map of quite a large area which required a considerable amount of time (months) and because of the occasional availability of equipment and bad weather conditions causing postponing of certain campaigns, the area was divided into adjacent sub-areas which were mapped in a considerably separated measuring days. Because of the rainfall changes from one campaign to another,...

Root and leaf changes in Salix nigra cuttings in response to increasing soil temperature
Salix nigra, black willow, is used for wetland restoration and streambank stabilization and like other wetland species has the ability to develop aerenchyma tissue to avoid root anoxia. Root aerenchyma development could be affected if the temperature of the rhizosphere increases as a result of climatic change. Root porosity (used as an indication of aerenchyma tissue) of S. nigracuttings grown under...

Performance studies of free-living tomato (Lycopersicon exculentum L.) rhizospheric Bacillus for their multiple plant growth promoting activity
The present investigation is based on the study of the diversity of Bacillus spp. isolated from tomato rhizosphere and their evaluation as plant growth promoter. A total of twenty eight rhizospheric gram positive rod-shaped bacteria (DPNSB-1 to DPNSB-28) were isolated on nutrient agar and confirmed as Bacillus spp. on the basis of phenotypic characterization. Carbon source utilization...

Productivity index rating of some soils in the Tolon/Kumbungu district of the Northern region of Ghana
Productivity indices (PI) provide a single scale on which soils may be rated according to their suitability for crop production. The study was to assess the productive potentials of selected soil series in the Northern region of Ghana viz, Nyankpala series (NS), Changnayili series (CS) and Kpelesawgu series (KS), to evaluate the current and future suitability of these soils and to suggest possible amendments...

Short term effects of cassava processing waste water on some chemical properties of loamy sand soil in Nigeria
The short term changes in the concentration of some of the major constituents of cassava waste water and their corresponding effects on some of the soil exchangeable cations were studied following surface application of cassava waste water. The leaching experiment with de – ionized water was carried out on soil inside column under conditions of saturated flow. Samples of leachate were taken at 10 cm...
