Nanoplastics: Methods, Exposure and Effects on Domestic, Farm and Wild Animals

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Nanoplastics (NPs) are synthetic polymer particles ranging in size from 1 nm to 1 μm that have been identified as a major concern for ecosystems and organisms due to their plethora of negative effects. The aim of this review is to provide a comprehensive overview of the knowledge relating to exposure and effects of NPs in domestic (i.e., farm ...

N availability after long-term organic farming in irrigated and rain-fed Mediterranean semi-arid grassy crops [PDF]

open access: yes, 2008
The use of manures and rotation with legumes in organic farming systems does not always guarantee the adequate nutrient supply to crops. We studied post-harvest N availability in a series of Mediterranean semi-arid rain-fed and irrigated organic fields ...

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

open access: yesJournal 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,
