The private land owning timber baron companies like Weyerhauser, Boise Cascade, Int'l Paper, Georgia Pacific, Roseburg Lumber, Pope & Talbot, and Bohemia Inc., they all bought into the idea of the 'Super Tree'.  A fast growing hybridized Douglas Fir that was suppose to allow a new crop of  trees to be harvested in as little as 40 years . They planted  millions of them.  They dumped horrendous amounts of Urea based fertilizer on them during the late, and cold, winter months every year.  What they got was over-stimulated trees that produced large soft water-saturated growth rings.  When milled the lumber drastically warped and/or broke as it dried.   How many remember this fiasco?   Why is this relevant?

The over stimulation also made the trees a prime host for this fungus.  Oops!

Now 40+ years, and millions of tons of fertilizer, later we have fungus infested forests plus our rivers, streams, and ground water contaminated by fertilizer and herbicide runoff.
