Repeated use of anion‐exchange membranes in soils alters the membrane surface and phosphate‐P exchange capacity

open access: yesSoil Science Society of America Journal, Volume 90, Issue 1, January/February 2026.
Abstract Anion exchange membranes (AEMs) are widely used to assess soil phosphorus (P) cycling. However, the routine reuse of AEM for soil extractions may impact the surface properties of AEM and thus phosphate‐P exchange. We evaluated changes in AEM surface morphology, chemical composition, and phosphate‐P exchange capacity after varying degrees of ...

Fruit and Vegetable Peels as Alternative Feed for Sustainable Poultry Production: A Solution for Small‐Scale Farms in Central and Southern Ethiopia

open access: yesVeterinary Medicine and Science, Volume 12, Issue 1, January 2026.
Fruit and vegetable peels were evaluated as alternative feed resources for small‐scale poultry production in central and southern Ethiopia. Survey data from 360 households and laboratory analyses showed that potato peel had the highest metabolizable energy and crude protein, while pumpkin peel exhibited the highest overall nutritional value.

Leaf Nutrient Remobilization and Its Relationship With Root Growth in Arabica Coffee

open access: yesInternational Journal of Agronomy, Volume 2026, Issue 1, 2026.
The flow of nutrients from mature leaves to priority sinks as young leaves and roots is one of the strategies for efficient use of nutrients. This study aimed to evaluate the relative remobilization (RR) of N, P, K, Mg, Cu, Fe, and Zn from mature to young leaves during the development stages of coffee fruits and its relationship with root growth in ...

Impact of a 6-wk olive oil supplementation in healthy adults on urinary proteomic biomarkers of coronary artery disease, chronic kidney disease, and diabetes (types 1 and 2): a randomized, parallel, controlled, double-blind study [PDF]

open access: yes, 2015
Background: Olive oil (OO) consumption is associated with cardiovascular disease prevention because of both its oleic acid and phenolic contents. The capacity of OO phenolics to protect against low-density lipoprotein (LDL) oxidation is the basis for a ...
