This season we have not needed liquids on our plants we attribute that to the strong compost teas and the amazing nutrient management plan. Can’t have one without the other. It’s the trifecta. First need food in the soil. Bringing the soil to life with compost tea and have right equipment brew and apply the teas."

“ DBS testing took all the guess work out of what our soil needed. We had a lot of hypotheses of what was wrong but the tests confirmed what we needed to know. I have nothing but the best to say for Sarah at DBS. I credit their soil analysis in 2015 a huge component in our top 10 placement in the emerald cup - I’d love to get my soil tested with them again.”
