Greenhouse research was conducted to determine the effects of soil application of humus, on dry matter and N, P, K, Ca, Mg, Fe, Cu, Zn, Mn and Na uptake of maize grown under calcareous and saline soil conditions. Stress conditions were obtained by adding 40% CaCO3 and 60 mM NaCl to the soil. Humus was applied to the soils at 0, 1 and 2 g kg(-1) doses at the beginning of the treatment. Solid humus and CaCO3 were mixed according to the application doses, and the total weight of the soil was adjusted to 5 kg. The mixture was homogenised and put into polyethylene-covered plastic pots (20 x 18 cm). A 60 mM NaCl solution was added to the salt-treated pots.
