Abstract: Solution culture experiments were conducted and the uptake kinetics and absorbing characteristics of ammonium and nitrate nitrogen were studied in six crops during differet growth stages by using a solution in which both ammonium-N and nitrate-N were present equally in amounts. The results showed th
