<div class="userStyles" style=" font-family: Arial; font-size: 12pt; color: #000000;">Dear APWG,<br>
<br>
Here in California where we have 14 million acres of Yellow Star thistles infesting our rangelands, a discovery in our test plots at the Town of Woodside's Kite Hill Wildflower Preserve in the San Francisco Bay area, shows that 90-100% of an infestation can be eliminated in 90 days, just with fertilizers and mulch.<br>
<br>
This method was invented by my company 30 years ago, The Reveg Edge, P.O. Box 361, Redwood City, CA 94064, adding fertilizers and mulch to get rid of weeds. When we needed to invent methods to replant 100-mile Tuscarora gas pipeline north of Reno in the cheatgrass-infested sagebrush desert. <br>
<br>
I use the A-01 Waypoint lab $32 soil test, data only in a bar graph format, and take my soil sample from the top two inches of the weed infested area, and sift through a 1/4 inch mesh screen to remove rocks and leaves to end up with a full quart. <br>
<br>
I sample the cheatgrass or the yellow star thistle soil, and another sample of the nearby soil where the desirable natives are producing seedlings.<br>
<br>
At the star thistle test plot at Kite Hill, we tested the soil and added organic fertilizer in fall, to a 3/4 acre site which had three million seedlings growing. 90 days later, 90% of the star thistle was gone.<br>
<br>
The thistles were replaced by dormant pasture seeds in the soil, which needed the nutrients to grow and use their allelochemicals to suppress the star thistle seeds from sprouting. <br>
<br>
The Preserve is open 24/7 and if anyone would like a tour, just contact me.<br>
<br>
The other method we use to completely get rid of the flammable weed grasses, is monthly mowing at 8-12 inches high, and that allows the dormant native seeds in the soil to take over, so we end up producing in weed-infested California grasslands, 95-99% weed-free wildflower meadows--without sowing any native seeds.<br>
<br>
Dozens of our California grasslands have been pushed to the brink of extinction by the exotics, and these two methods could rescue our Listed species, like the Tarplants, Lessingias, Marin Dwarf flax, Purple Amole, Thornmints and the like, which are slowing being pushed to extinction.<br>
<br>
Since 1992, I have restored 800 acres of California grasslands, back to 95% or better native cover. And the fertilizer methods against the star thistles could rescue 14 million acres in California and 100 million acres of cheatgrass in the Great Basin, and make them productive again.<br>
<br>
The Kite Hill test plot in one year, when from zero pasture-grass forage when it was solid star thistle, to an unirrigated meadow producing 7,400 pounds per acre.<br>
