What type of extra yield does SEER Rockdust give to potatoes, corn, barley, grass?
We cannot say for farming land of differing soil types. Research needs to be done, records kept and samples taken by those who experiment with it. We have a “poor soil” terrace here, ph 4.5. Plants, even peas, do not do well. A 2 year dose of SEER Rockdust was applied to one half and we doubled the yield by the 2nd growing season. The 2 year dose was used up within the 2 years so we have now put a 10 year dose on the same half and we will see if we can more than double the yield.
