Climate Determines Soil Humus Type, Impacting Agriculture and Ecosystems.
The type of humus in soils in northern Karnataka depends on the soil type and climate. Lateritic soil has fulvate humus, while forest and black soils have humate-fulvate or humate humus. Lateritic soil lacks a certain humus fraction, black soil lacks another, but forest soil has both. Climate strongly influences the nature and composition of humus in these soils.
