This is Doug Hendrickson and his son Adam who farm in
Warrick County. They have taken
advantage of the On Farm Network guided stalk sampling tests for their
reclaimed mine land. They feel that it
is a great tool to assist them in checking their nitrate levels for corn
fields.
Don Ryan is demonstrating the sampling method for On Farm
Network where stalk samples are taken from mature corn plants and analyzed for
residual nitrate concentration in the stalks.
These samples along with aerial yield maps taken of the fields in summer
help farmers assess their cultivation and fertilizer application practices.
Some OFN sampling is
being done strategically on adjacent field areas where cover crops have been
planted next to areas where cover crops have not been used to assess
differences in nitrate use in corn.
