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.

Tall Pine Trees. Tall pines reach 100 feet or more. Though white pine (Pinus strobus) may remain at a height of 50 to 80 feet, it has the potential to reach 150-plus feet in maturity, according to the Clemson University Extension.White pines display blue-green needles at a rapid growth rate of over 2 feet every year.all Pine Trees.
