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. ...
Illegal harvesting threatens fruit production and seedling recruitment of Balanites aegyptiaca in Dinder Biosphere Reserve, Sudan
(Elsevier, 2021-09)
Illegal harvesting negatively affects the forest tree populations, particularly in sub-Saharan Africa, but little is known how fruit production and seedling recruitment are impacted. We assessed recruitment parameters of ...
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 ...

(Current Horticulture, 2021-12-03)
This pilot research study assessed the effect of bat guano and rabbit urine as organic nutrient sources for growing Spinacia oleracea (spinach) under a non-circulating hydroponic system. Three treatments; bat guano (5 g/L ...
Using Trophy Hunting to Save Wildlife Foraging Resources: A Case Study from Moyowosi-Kigosi Game Reserves, Tanzania
(MDPI, 2022-01-04)
Globally, the role of trophy hunting in wildlife conservation has been a topic of much debate. While various studies have focused on the financial contribution of trophy hunting towards wildlife conservation, little is ...

(MDPI, 2020-01-13)
The domestication of novel or hitherto wild food crops is quickly becoming one of the
most popular approaches in tackling the challenges associated with sustainable food crop production,
especially in this era, where ...
