摘要

extractant composition of humic substances and a process for obtaining an extract containing humic substances.; The composition comprises at least two components selected from components A, B and C, wherein component A comprises one or more basic compounds; component B comprises one or more chaotropic compounds with capacity to destroy intermolecular weak interactions; and component C comprises one or more compounds with sequestering capacity, complexing or chelating metal ions. The composition can be used to extract humic substances in active form and in high yield, from an organic substrate. The extract containing humic substances is obtainable by a process comprising contacting said organic extractant composition with said substrate, with optional addition of water, and separating the resulting liquid phase. Application in Agriculture.
