For all finger meters and CNH air planters, this premium graphite extends wear life and improves meter performance. Graphite provides the lubrication needed to prevent wear on meter components. It also improves seed flow and can improve meter performance. But, as with most things, a little is good, but a little more can be bad. A teaspoon per bag (80,000 seeds per unit) is recommended. With heavy seed treatments, increase to 2 teaspoons. It is important that new meters, or meters that have been cleaned, get a good, early dose of graphite to prevent seed treatment from sticking to bare metal. Mix the graphite into the seed to prevent uneven settling. Precision Graphite is available in 1# and 5# containers.
