Minimal Dataset for Lead-Induced Nutrient Imbalance and Biochar-Mediated Nutrient Homeostasis Responses in Purslane (Portulaca oleracea L.)

This dataset contains the raw experimental data underlying the manuscript entitled "Lead-Induced Nutrient Imbalance and Biochar-Mediated Nutrient Homeostasis Responses in Purslane (Portulaca oleracea L.)". The dataset includes replicate-level measurements of plant growth parameters, shoot Pb concentration, and macro- and micronutrient concentrations under different lead and biochar treatments.
