Soil fertility and land sustainability in Usangu Basin-Tanzania
(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 ...
Accumulation and bioconcentration of heavy metals in two phases from agricultural soil to plants in Usangu agroecosystem-Tanzania
(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 ...
Land use patterns influence the distribution of potentially toxic elements in soils of the Usangu Basin, Tanzania
(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 ...
Characterization of soil phosphate status, sorption and saturation in paddy wetlands in usangu basin-Tanzania
(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. ...
Towards agricultural sustainability: Status and distribution of copper in Usangu agro-ecosystem, Tanzania
(Elsevier, 2022-02-28)
Despite the positive role of copper (Cu) in plants and animals, excessive amounts have environmental and health
effects. Cu has been excessively accumulating in agricultural soils worldwide due to increased agrochemicals ...
Toxic metals in East African agro-ecosystems: Key risks for sustainable food production
(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 ...
Characterization of land use influence on soil phosphate bioavailability in Usangu agro-ecosystem-Tanzania
(Elsevier B.V., 2021-12)
Phosphorus (P) is an important nutrient required for plant growth. Land use influences concentration and bioavailability of P in agricultural soils. About 198 soil samples (0-30 cm soil depth) were collected from three ...
Towards sustainability: Threat of water quality degradation and eutrophication in Usangu agro-ecosystem Tanzania
(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 ...
Increasing agricultural soil phosphate (P) status influences water P levels in paddy farming areas: Their implication on environmental quality
(Elsevier Ltd., 2022-10-03)
Intensive paddy farming activities involve higher use of irrigation water and agrochemicals to increase crop productivity per unit area. However, a practice may result in environmental challenges due to nutrient loss and ...
