The Trial of Paramagnetic Basalt Grit on Strip Cultivation is already giving great results in year 1. Paramagnetism promotes the uptake of minerals by plants. A 2-tonne dose should sustain this effect for a few years while re-mineralising the soil.
Read Phil Callahan's books to know more about it.In the coming years, we are going to be able to measure difference in 3 crops each time.
Basalt grit can be spread with a lime spreader. Take a look here for the measurement of the exceptionally high paramagnetic value of 8,000 - 10,500 cgs for our basalt grit:
