Dave and others-- Back a few weeks ago you posted the analysis listed below. It got me to thinking about possibly spraying horsetail as a way to increase sulfur content.
Our soil analysis shows that our calcium/magnesium ratio is way out of balance. This is partly due to the fact that our local lime is high in magnesium. This results in a "tight" soil. For example, we almost always have problems with foxtail. We have applied high cal lime but the problem continues. We've been advised that applying sulfur to the ground would enable the cal/mag to come back into balance. Perhaps the horsetail would be a more natural way of doing that, unless of course, the amounts contained are insignificant. Comments? Suggestions? Thanks. "Concentration of trace minerals, mg/L or ppm Element Valerian Horsetail Ca 307 414 Fe 7.4 0.2 Mg 271 186 Mn 2.1 0.9 P 55 1116 K 2650 888 Si 12 177 Na 3 2 S 144 560 Zn 5.6 0.1 Isn't this interesting? 508 has some Si as expected, but it's really high in P and S, and has fair amounts of Ca and K. Who would have expected that? Meanwhile valerian 507 has lots of K. Ghroman describes horsetail as really a Ca plant that has a lot of Si to balance out the Ca. So what horsetail provides is far more than merely Si. Courtney and Kolisko point out that horsetail tea should be fermented for maximum activity. It gets pretty smelly when you do that, giving off H2S. Now we know why." __________________________________________________ Do You Yahoo!? Yahoo!
