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.
On a perfect weather year, and no competition from grass or weeds, we have seen over 6 ft of growth in one year! This spruce if given sufficient room to grow will easily grow to over 100 feet tall and be 40 feet wide with spreading branches at the base and will live over 100 years.he Norway Spruce is also a dominant tree in the Carpathian Mountains of Romania and Ukraine shown above. IDENTIFICATION First stand back--if this evergreen is a tree that is 20 foot tall or larger it should have a dark. green color with pendulous (arching upward) branches.
