he days are getting longer and temperatures are slowly rising. That can only mean that corn planters will soon be running in fields across Indiana. If you haven’t taken the time to go over your planter or have it inspected and serviced by your local dealer, please take the time to do so before planting begins.
A well-maintained planter will lessen the risk of down time and ensure a timely finish to planting this spring. Another benefit to a smooth-running planter will be a greater likelihood of uniform stand establishment; an important factor for achieving maximum yields (Doerge et al., 2002; Nielsen,2001; Nielsen, 2004).
Several seed companies plus a number of planter dealers offer planter unit testing with the use of several planter test stands on the market. One of the more popular test stands being used is called the Meter Max™, manufactured by Precision Planting™ (http://precisionplanting.com/). This type of planter test stand not only measures the accuracy of seeding rate, but can also give you an idea of the uniformity of the seed drop by virtue of the seed dropping onto a horizontal seed belt.
