Human Health Risk Assessment From Exposure to Toxic Metals in Soils and Leafy Vegetables in Smallholder Farms of Northeastern Brazil

Journal of Applied Toxicology, EarlyView.
ABSTRACT This study assessed human health risks associated with exposure to potentially toxic metals (PTMs) in soils and leafy vegetables cultivated in smallholder agricultural systems in Northeastern Brazil. Soil and vegetable samples were collected from 18 agricultural areas and analyzed for cadmium (Cd), chromium (Cr), copper (Cu), iron (Fe), nickel

Accumulation and distribution of cadmium at organic-mineral micro-interfaces across soil aggregates

Ecotoxicology and Environmental Safety
Soil amendments are crucial in regulating cadmium (Cd) distribution as aggregates of varying sizes have different capacities to retain soil Cd. Directly observing the Cd distribution within aggregates and understanding their interactions with minerals ...

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,

The Influence of Soil Properties on the Agronomic Efficacy of Rock Dust: A Comparative Analysis of a Semiarid Ultisol and Global Soil Types

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background: Enhanced rock weathering (ERW) using silicate rock dust is a promising strategy for soil remineralization and carbon dioxide removal. However, its agronomic efficacy is highly dependent on soil properties. Aim: This study provides a comprehensive comparative analysis of the influence of soil type on the performance of rock dust ...

Food Security Versus Environmental Health: The Nitrogen Dilemma

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Nitrogen is an essential element for plant growth and, consequently, crop production. However, the cycling of nitrogen in the environment can have negative effects. Here, we review the historical development of scientific and public awareness of these effects and the influence this has had on political action to control them.

Effects of Crop Rotation and Hydrogel Application on Soil Biological Properties and Wheat Biomass Production in Drylands

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background and aim Conservation agriculture (CA) is rapidly gaining traction to promote sustainable crop production, focusing on minimum soil disturbance, permanent soil cover, and strategic crop rotation. Moreover, hydrogel is increasingly being used to improve water retention, including in combination with CA, particularly in water limited ...

Variation in antioxidant potential of Vigna unguiculata grown in pure and amended soil

Kuwait Journal of Science, 2020
The variation in antioxidant capacity on Vigna unguiculata was determined by carrying out the pot experiment in pure and in amended soil. After amending the soil, the suitability of sewage sludge for agricultural purposes was assessed. V. unguiculata was
