Thermopotash has been tested starting about five years ago, that's where they got the data on coffee taste and quality, there were other crops as well ... and i think they ran a test on carrots before that? - friendly farmer involved, if memory serves ... this was the TK47, basically fritted greensand, same stuff in different form, possibly some trace minerals added, i don't recall exactly
The only difference between TK and simple ground greensand is the fritting, the main effect of which is on rate of solubility ... the distinction between 'micronised' and 'granular' in products announced monday will presumably have effect on that rate as well ... ? - i think, just guessing here ... the more chunky the grain, the more you spread per square yard, and the longer it lasts between applications, presumably
Less frequent application means driving equipment over the roots of your coffee trees less often, trees like it when you stay off their roots ... and that's all need to get this project really rolling - coffee ... capture a reasonable slice of the fert market in coffee, and we're off ... you could call this is the Ol' Blue Eyes Theory of Verde -
