Sol,
Thanks for starting this topic. I have been thinking about this as well. Last winter, I bought one large bag of crushed granite, same one that Lynn has mentioned. I had to wash some of the fine particles out since it had too much dust in it. I also purchased small bag of dolomite powder and bone meal. I mixed them in organic soil where I used them in large wood planter I had my seedlings growing. That planters had 100+ seedlings and they were resistant to heavy rains we had in May. I had lost almost all except a few in other locations where I did not use rock dust and bone meal. I had 1 yard of crushed granite and manufactured sand delivered last August so I am using it in all soil mixes now. Also using sifter to get the dust out first however leaving some dust behind. We will see how semps will do in May/June.
I am using a few different biofungicides what seems for short time.
Using Quick Start helped them grow faster and healthier as well.
PaleoTemp, that is very interesting topic about thiamine. I may need to give it a try on trial basis to increase resistance for heat stress when soil get wet. I need to learn more to see what form to use, legumes powder may be?
