From waste to resource: Garlic peel‐derived proteases (Allium sativum) for nematode control

open access: yesEnvironmental Progress &Sustainable Energy, Volume 44, Issue 4, July/August 2025.
Abstract This study aimed to prepare a protease‐rich extract from garlic peel (Allium sativum) and evaluate its nematicidal potential. The garlic peel was crushed, suspended in distilled water, and the obtained extract was subjected to filtration, centrifugation, and dialysis to concentrate the proteases. The nematicidal activity was tested in vitro on

Climatic and Edaphic Drivers of Soil Organic Carbon and Pyrogenic Carbon Stocks Across Elevation and Disturbance Gradients in Colombian Andean Forests

open access: yesGlobal Change Biology, Volume 31, Issue 7, July 2025.
This study examined soil organic carbon (SOC) and pyrogenic carbon (PyC) stocks in tropical Andean soils across elevation and disturbance gradients in Colombia. SOC stocks to 100 cm depth averaged 433.10 Mg C ha−1 while PyC was 34.13 Mg C ha−1. Key drivers of PyC stocks include soil clay (%), mean annual precipitation (PA), pH, Ca, and NDVI, which ...
