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.
Picea abies 'Cupressina' - Columnar Norway Spruce. The species Norway Spruce originates from the mountains of central Europe, where it can be found at elevations as high as 6,000 ft. This cultivar, the Cupressina Norway Spruce, is fastigiate, meaning it is very narrow with a tight branching habit.Because of it's growth habit it's a prized selection on urban and suburban properties and in gardens where a strong, evergreen vertical element is required.Though it's classified as a dwarf, this conifer can be expected to grow to a height of 30'-40' in height and 8'-10' in diameter.ecause of it's growth habit it's a prized selection on urban and suburban properties and in gardens where a strong, evergreen vertical element is required.
