One of the most important jobs a peanut farmer can do to ensure good yields is to use inoculation for nitrogen fixation in both old ground and new. David Jordan, North Carolina State University Extension peanut specialist, emphasized that there is no substitute for successful inoculation in new peanut ground. But the practice is a must on all ground where peanuts are planted. He stressed that with longer rotations in place and some expansion to new ground, making sure inoculants perform well is very important. Correcting a nitrogen deficiency with ammonium sulfate or other sources of nitrogen is very expensive, he says. On new ground with no history of peanut production, Jordan recommended an in-furrow inoculant and a peat-based inoculant in the hopper with seed. He said this is for insurance for failure, including clogs and product issues.
