Spatial distribution of heavy metals in soil with distance from Tazama pipeline through the Mikumi National Park, Tanzania

A total concentration of six studied heavy metals Arsenic (As), Lead (Pb), Chromium(Cr), Mercury (Hg) Cadmium (Cd) and Copper (Cu) were measured in soil across distances from TAZAMA pipeline in transects which have incidences of oil spillage and those which have no history of oil spillage. All studied heavy metals were detected in the study area. As, Pb and Cr were detected in both transects, that is, with oils spills...

Characterization and agricultural potentials of some pedons derived from sand stone parent rock near Abeokuta, Southwestern Nigeria

Successful crop production requires the knowledge of soil variation and the evaluation of the agricultural potentials of the land. Detailed land resource survey of approximately 100 ha land in Abeokuta North Local Government Area of Ogun State was carried out. Identified soil mapping units were examined in modal profiles. The soils were classified using the USDA Soil Taxonomy, FAO/IUSS World Reference Base (WRB) system...

Evaluation of some selected forage grasses for their salt tolerance, ameliorative effect and biomass yield under salt affected soil at Southern Afar, Ethiopia

Soil salinity is a growing problem on many irrigated parts of arid and semi-arid areas of Ethiopia. Utilization of improved salt-tolerant forage grasses help farmers to maximize production and reclaim saline soil. A study was conducted at Werer Agricultural Research Center (WARC) from 2012 to 2014 to evaluate performance of four forage grass species of salinity tolerance, ameliorative effect and biomass production. The...

Impacts of soil and water conservation on crop yield, soil properties, water resources, and carbon sequestration: A review

This paper reviews the impact of soil and water conservation (SWC) measures on crop yield, soil properties, water resources and carbon sequestration. Land degradation due to soil erosion in Ethiopia is too severe which affects the livelihood of a community and ecosystem functions. The dry and highland part of the country was identified as seriously vulnerable to land degradation because of soil erosion. And, soil...

Soil characterization and evaluation of blended (YaraMila cereal) fertilizer for bread wheat (Triticum aestivum L.) production at Aleltu areas in North Shewa Zone of Oromia region

The main objective of the study was to characterize the soils on the basis of selected soil physicochemical properties and to evaluate the effects of blended fertilizer (YaraMila cereal) applications on yield and yield components of bread wheat on the major soil types in the study area. The field experiment involved 5 treatments (control, three rates of blended fertilizer and recommended nitrogen and phosphorus...
