On Farm Network Part 2

By Jamen Frederick

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.
