  <dc:description>This dataset was obtained by researchers through field sampling and scientific testing. The Niuxintaobao Core Demonstration Area for Green Planting and Breeding Technology in Saline-Alkaline Paddy Field Wetlands is located within the Niuxintaobao Wetland Farm in Daan City, Baicheng City, Jilin Province, covering an area of 3,000 mu. Soil samples were collected in April 2021 at a depth of 0&amp;ndash;20 cm from the surface layer, with a total of 28 sampling points. The soil testing indicators include pH, EC, ENa, CEC, ESP, CO₃&amp;sup2;⁻, HCO₃⁻, Cl⁻, SO₄&amp;sup2;⁻, Na⁺, Mg&amp;sup2;⁺, K⁺, Ca&amp;sup2;⁺, salinity, SAR, TN, TP, TK, AN, AP, and AK.</dc:description>
