Influence of farmers’ socio-economic characteristics on nutrient flow and implications for system sustainability in smallholdings: a review
(Frontiers in Soil Science, 2023-04-14)The rise in global human population, coupled with the effects of climate change, has increased the demand for arable land. Soil fertility has been the most affected, among other things. Many approaches to soil fertility ... -
The Influence of Fertilizers on the Behavior of Fluoride Fractions in the Alkaline Soil
(Elsevier, 2021-08-23)It has been established that fluoride bioavailability in the soil is defined by the form which it exists rather than the amount of total fluoride. In the soil, fluoride exist in different fractions such as water soluble ... -
The influence of gold mining on radioactivity of mining sites soil in Tanzania
(International Journal of Environmental Quality, 2022-02-17)The activity of 226Ra, 232Th and 40K in soil samples were measured by gamma spectrometry using high purity germanium detector. The study involved 40 samples from four divisions: 10 samples each were drawn from the control ... -
Influence of land use change on nitrate sources and pollutant enrichment in surface and groundwater of a growing urban area in Tanzania
(Springer Nature Switzerland AG., 2021-01-31)In the present study, 3-year (1997, 2008 and 2017) satellite images as well as different hydro-chemical parameters, nitrogen and oxygen isotopic composition of nitrate were used to examine the impacts of land use and land ... -
Influence of Macrophyte Types towards Agrochemical Phytoremediation in a Tropical Environment
(International Journal of Engineering Research and General Science, 2014-09)The presence of agrochemicals waste water from agricultural fields poses major environmental and human health problems which may be solved by phytoremediation technologies. Phytoremediation is the use of plants to remediate ... -
Influence of metal contaminants and antioxidant additives on storage stability of biodiesel produced from non-edible oils of Eastern Africa origin (Croton megalocarpus and Moringa oleifera oils)
(Elsevier Ltd., 2015-10-15)The effect of metal contents and antioxidant additives on the storage stability of biodiesel produced from less common non-edible oils of Eastern Africa origin (Croton megalocarpus and Moringa oleifera) were evaluated and ... -
Influence of phosphate fertilizers on the radioactivity of agricultural soils and tobacco plants in Kenya, Tanzania, and Uganda
(Springer Berlin Heidelberg, 2023-06-20)Three brands of NPK fertilizers that contain variable concentrations of natural radioactivity are commonly used in tobacco plantations in Kenya, Tanzania, and Uganda. Tobacco plants are known for hyper-accumulation of ... -
The influence of physical-chemical variables on the spatial and seasonal variation of Chlorophyll-a in coastal waters of Unguja, Zanzibar, Tanzania
(African Journals Online, 2018-12-11)Chlorophyll-a (Chl-a) concentrations were measured at four sites around Unguja, Zanzibar during the northeast (NE) and southeast (SE) monsoon seasons. Data for Chl-a, nitrate, phosphate, ammonia, dissolved ... -
Influence of scoria and pumice on key performance indicators of Portland cement concrete
(Elsevier Ltd, 2019-02-10)Cement industries have a huge CO2 signature that can be reduced in an effort to mitigate climate change via precise cement substitution with supplementary cementing materials (SCMs). The substituting materials and their ... -
