CHEMICAL CHARACTERISTICS OF A NATURAL SOIL LEACHATE FROM A HUMIC PODZOL
A leachate, collected in the field in a lysimeter placed between the Ae and Bhf horizon of a Humic Podzol in Newfoundland, was analyzed by chemical and spectroscopic methods.About 87% of the dry, ash-free weight of the leachate was fulvic acid, the remainder consisting mainly of polysaccharides and...
