Potassium dynamics under enset (Ensete ventricosom cheesman) farming systems of Sidama zone, Southern Ethiopia

Potassium dynamics of soils is constituted by constantly changing relationship between soil K forms, and this relation is affected by some soil physical and chemical properties. Most Sidama (south Ethiopia) farmers grow enset crops which have high K requirements. The soils were collected from Awassa-Zuriya and Dale districts; ’Woinadega’ (warm subtropical climate) and Hula district ‘Dega’ (wet,...

Soil erosion magnitude of upland farming practices in Bataan

There are factors affecting erosion such as climate, soil type, vegetation and topography. Upland areas are denuding exponentially due to the fact that those people looking for livelihood had little concern and awareness on environmental sustainability and management. Upland farming practices that are easy like weeding, pest control and fertilization were often carried out without soil erosion control and water...

Spatial distribution of organic carbon and nitrogen in soils related to flood recurrence intervals and land use changes in Southern Québec, Canada

Several hydromorphological and soil factors may be the cause of variations in the total organic carbon (TOC%) and total nitrogen (TN%) content of riparian soils. Despite the importance of these two essential components in soil-forming processes, few studies have focused on the variability of carbon and nitrogen content for soils subjected to frequent flooding. Successive floods may in fact result in soil depletion....
