Microbial additives are not cheap, analyzing the soil and then blending the right and missing microbes is a little bit more involved than just adding nitrogen to the soil which is what most growers have done in the past and still do today. So Kiwa Bio-Tech is on the right path with their extensive research programs these last couple of years and will pay off in the long run!!! As an example have y-all noticed how tasteless most fruits and vegetables are now a days??? ORGANIC IS THE ONLY WAY TO GROW!!!
