Abstract
The amount and proportion of NO3-, NH4+, K+, Ca2+ and Mg2+ ions transported with cell sap depended on the fertilizer form applied to soil and the age of maize plants; the amount and proportion of the cations also depended on their interaction in soil during absorption by roots. The direction of the concentration gradients of distribution of NO3-, K+, Ca2+ and Mg2+ in different leaves coincided in plants given mineral fertilizers, while the concentration gradient of distribution of NO3- was in opposite direction to that of cations in plants given FYM. There was a close association between contents of cations and NO3- in the soil-plant system, whose nature mainly depended on environmental factors.
