Soil acidity stress: A faba bean (Vicia faba L.) cultivation challenge in Ethiopia, mitigation, and future perspectives

Agrosystems, Geosciences &Environment, Volume 9, Issue 1, March 2026.
ABSTRACT Soil acidity is among the most important abiotic stresses globally constraining agricultural land and crop productivity. Globally, about 30%–40% of total arable land is under the influence of acidic soil. In Ethiopia, approximately 43% of arable land and productive areas are constrained by acidic soil.

Toxicity of three comercial tannins to the nuisance invasive species Limnoperna fortunei (Dunker, 1857): implications for control [PDF]

, 2011
Adding biocides to water is one strategy to control macrofouling organisms. A natural biocide that helps to prevent/control macrofouling of Limnoperna fortunei (Dunker, 1857) on human installations is one way to minimize environmental impacts of ...

Transposable elements: Functional aspects and applications as drivers of crop innovation

Crop Science, Volume 66, Issue 2, March/April 2026.
Abstract Transposable elements (TEs), which were once relegated to the status of genomic parasites, are today accepted as important agents of plant genome evolution and adaptation. This review integrates evidence pointing to their dual function as drivers of genetic diversity and instability, with a focus on their contribution to phenotypic innovation,
