How much Blueberry Booster should I apply this spring? This affordable tester gives you a means of checking your soil pH from year to year. As an added bonus the fertility function reads the combined levels of nitrogen, phosphorus and potash. Although by no means equal to a lab soil test, it gives you a ballpark indication whether your soil fertility is high or low. The third function is soil temperature. Is it warm enough to plant your tender vegetables?
A simple, reliable tester at a reasonable price.
