Calcium as a confounding variable in phosphorus attribution: A commentary on Hu et al. (2025)
This letter questions the sole attribution of enhanced plant growth and arsenic accumulation to P availability in Hu et al. (2025), arguing that Ca, a co-delivered nutrient in all treatments, may be a confounding factor. Emerging evidence highlights Ca's critical role in plant growth, water use efficiency, and arsenic uptake, necessitating careful consideration in experimental designs. The letter recommends experimental designs that disentangle P and Ca effects to strengthen the mechanistic understanding of nutrient-driven phytoremediation.
