Humic acid is a principal component of humic substances, which are the major organic constituents of soil (humus), peat, coal, many upland streams, dystrophic lakes, and ocean water.t is produced by biodegradation of dead organic matter. It is not a single acid; rather, it is a complex mixture of many different acids containing carboxyl and phenolate groups so that the mixture behaves functionally as a dibasic acid or, occasionally, as a tribasic acid.
Noteworthy Characteristics. Picea abies, commonly called Norway spruce, is a large pyramidal evergreen conifer that is native to the mountains of northern and central Europe east to the Urals. In its native European habitat, it typically matures to 100-150' (occasionally to 200') tall.
Identifying characteristics: Growth Type: Perhaps one of the most important survival trees in the Eastern forest. Pinus strobus is the tallest tree in Eastern North American. It can grow to a height of 160 - 190 feet tall. There are accounts of the pre-colonial eastern white pines reaching 230 feet tall. Height: Can reach heights of 160 - 190 feet. Leaves: Needles, which grow in sets of 5 needles per fascicle.
