%X Cucumber was cultured in open-top CO2 controlled chambers to study the interactive effects of elevated CO2 and potassium (K) on soil quality chemical properties.The results indicated that N and P nutrient contents in soil decreased at elevated CO2 and higher K supply,and K nutrient content increased with the increase of K supply.Higher K supply (200 and 300 mg/kg)and elevated CO2 reduced NO3-,PO43-,Ca2+ and Mg2+ contents in soil.Therefore,in the future elevated environment higher K supply can improve the nu...
