Accumulation and bioconcentration of heavy metals in two phases from agricultural soil to plants in Usangu agroecosystem-Tanzania
Mng’ong’o, Marco; Munishi, Linus; Ndakidemi, Patrick; Blake, William; Comber, Sean; Hutchinson, Thomas (Heliyon, 2021-07-07)The build-up of heavy metals (HM) in agricultural soils accelerates the HM uptake by plants, which could potentially affect food quality and food safety. Here we studied the status and bioaccumulation of HM from soils to ... -
Assessment of arsenic status and distribution in Usangu agro-ecosystem-Tanzania.
Mng'ong'o, Marco; Comber, Sean; Munishi, Linus; Blake, William; Ndakidemi, Patrick; Hutchinson, Thomas H (Elsevier Ltd., 2021-06-09)This study was conducted to assess arsenic (As) status and distribution in Usangu agroecosystem-Tanzania, including three land use. About 198 soil samples were collected in ten irrigation schemes in three land uses. Total ... -
Characterization of soil phosphate status, sorption and saturation in paddy wetlands in usangu basin-Tanzania
Mng’ong’o, Marco; Munishi, Linus; Blake, William; Ndakidemi, Patrick; Comber, Sean; Hutchinson, Thomas (Elsevier Ltd., 2021-09)Phosphorus (P) is a vital plant macronutrient required for plant growth which usually available in limited amount. P availability for plant uptake in highly weathered soil is controlled by soil erosion and high fixation. ... -
Land use patterns influence the distribution of potentially toxic elements in soils of the Usangu Basin, Tanzania
Mng’ong’o, Marco; Comber, Sean; Munishi, Linus; Ndakidemi, Patrick; Blake, William; Hutchinson, Thomas (Elsevier Ltd., 2021-12)Spatial distribution of Potentially Toxic Elements (PTEs) in agricultural soils in Usangu Basin (Mbeya Region)-Tanzania were conducted. The study included three land-use types (paddy farming, maize farming, and conserved ... -
Potentially toxic elements status and distribution in Usangu agroecosystem-Tanzania
Comber, Sean; Munishi, Linus; Ndakidemi, Patrick; Blake, William; Hutchinson, Thomas (Elsevier, 2021-08)This study was conducted to highlight status and distribution of potentially toxic elements (PTEs) in Usangu agroecosystem-Tanzania. The study involved 198 soil samples from 10 irrigation schemes including three land use. ... -
Soil fertility and land sustainability in Usangu Basin-Tanzania
Mng’ong’o, Marco; Munishi, Linus; Blake, William; Comber, Sean; Hutchinson, Thomas; Ndakidemi, Patrick (Heliyon, 2021-08-09)Soil fertility determines crop growth, productivity and consequently determines land productivity and sustainability. Continuous crop production exploits plant nutrients from soils leading to plant nutrient imbalance, thus ... -
Towards sustainability: Threat of water quality degradation and eutrophication in Usangu agro-ecosystem Tanzania
Mng’ong’o, Marco; Munishi, Linus; Blake, William; Comber, Sean; Hutchinson, Thomas; Ndakidemi, Patrick (Elsevier, 2022-08-01)The agrochemicals and nutrient losses from farming areas such as paddy farming significantly dictate quality and eutrophication of the freshwater resource. However, how farming and land use pattern affect water qualities ... -
Toxic metals in East African agro-ecosystems: Key risks for sustainable food production
Mng’ong’o, Marco; Munishi, Linus; Ndakidemi, Patrick; Blake, William; Comber, Sean; Hutchinson, Thomas (Elsevier B.V., 2021-09-15)The dramatic increase in world population underpins current escalating food demand, which requires increased productivity in the available arable land through agricultural intensification. Agricultural intensification ...
