The relationship between cellular protein content and selenium accumulation in freshwater microalgae

Integrated Environmental Assessment and Management, EarlyView.
Abstract Variability in the bioconcentration of selenium (Se) by primary producers at the base of the food web results in uncertainty in predictions of bioaccumulation and ecological risk to higher trophic level organisms. Water chemistry, speciation of Se, and periphyton community composition have all been suggested as factors that contribute to ...

Farmers' Soil–Water Management Practices and Perspectives on Soil Salinization in Mirab Abaya District, Gamo Zone, Southern Ethiopia

Irrigation and Drainage, EarlyView.
ABSTRACT Soil salinization is a critical threat, impacting 20% of the world's irrigated lands and jeopardizing food security. In Ethiopia's Mirab Abaya district of the Gamo Zone, unsustainable irrigation methods exacerbate this issue. This paper examines local farmers' soil–water management systems and their awareness of salinization, aiming to educate

Biochar amendment decreases soil microbial biomass and increases bacterial diversity in Moso bamboo (Phyllostachys edulis) plantations under simulated nitrogen deposition

Environmental Research Letters, 2018
Biochar amendment has been proposed as a strategy to improve acidic soils after overuse of nitrogen fertilizers. However, little is known of the role of biochar in soil microbial biomass carbon (MBC) and bacterial community structure and diversity after ...

Edaphic Controls Override Climatic and Management Effects on Soil Organic Carbon in Southern African Agroecosystems

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Understanding the relative importance of climatic, edaphic, and management controls on soil organic carbon (SOC) is essential for improving SOC prediction and land management in data‐scarce agroecosystems. Aim This study quantified SOC drivers across Southern African agroecosystems using 655 observations covering climatic variables,
