Effectiveness of humic compounds in dependence on calcium content in water tomato cultures

K. Leonowicz-Babiak

Abstract


The influence of Na-humate and its fractions on dry weight increment of tomato seedlings in water culture and their calcium uptake in conditions of its deficit in the medium were investigated. Only fraction II of Na-humate was found to exert a significant effect; unfractionated Na-humate and fraction I had no noticeable influence.
