Transport of humic substances into leafs

This bachelor thesis simulates leaf foliar fertilization and describes transport processes of humic substances. Experiments were performed for two areas. The first focused on the flow through the plant cuticle as the main selective barrier. In the second one the transport of humic substances to the leaf was studied. The diffusion process was evaluated by the concentration loss of lignohumate solutions, which served as the medium of humic substances in the solution - leaf model. The results showed the effect of cuticle on nutrient penetration and its dependence on its condition. New findings are the transfer processes of humic substances into the leaves, that have proved effective in a short period of time, mainly at higher concentrations
