- Anton Lokshin led a Mediterranean field experiment simulating dust deposition on plant leaves, which showed that dust application increased plant macronutrient and micronutrient concentrations.
- Atmospheric dust settled on the mildly acidic leaf surfaces, dissolved, and released elements such as phosphorus and iron that were taken up by the plants.
- Ben‑Gurion University researchers found that leaf‑based nutrient uptake may be an important, previously overlooked contribution to plant nutrition in nutrient‑limited ecosystems.
- New Phytologist published the study in 2026, framing the findings as a shift from a soil‑centric view of nutrient acquisition toward a vegetation‑mediated pathway.
- Ariel University’s Dr. Daniel Palchan contributed to the analysis of dust‑deposition estimates and soil nutrient data across regions.
Why it matters: Plants in nutrient‑limited ecosystems gain a substantial nutrient source from atmospheric dust, while the traditional soil‑centric paradigm loses primacy; this insight reshapes ecosystem nutrient budgeting, improves models of carbon sequestration, and informs agricultural practices that exploit foliar dust uptake to boost crop nutrition.
