Influence of duct configurations on the performance of solar-assisted heat pump dryer for drying tobacco leaves
(NM-AIST, 2023-08)nadequate storage facilities and preservation techniques lead to a decrease in the quality of agricultural products. Application of modern processing techniques has reduced post-harvest losses of agricultural crops. ... -
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 ... -
