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.
Let me tell you a little more about why I like it. Norway spruce is native to northern Europe but for the past 100 years it has been extensively planted across Pennsylvania. It is fast growing and can put on two feet of height growth each year. At maturity they can be 100 feet tall and have a life span of centuries.
