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

This dataset contains the replicate-level experimental data underlying the manuscript entitled “Lead-Induced Nutrient Imbalance and Biochar-Mediated Nutrient Homeostasis Responses in Purslane (Portulaca oleracea L.).” It includes shoot fresh weight, shoot dry weight, shoot height, shoot Pb concentration, macro- and micronutrient concentrations, and calculated nutrient uptake values for 27 independent pots under different Pb and biochar treatments. Version 2.0 includes corrected shoot dry weight data and newly calculated pot-level uptake values for N, P, K, Ca, Mg, Fe, Cu, Zn, Mn, and B.
