Nitrogen Sampling

I did some sampling for Nitrogen tests today.  We use the Pre-Sidedress Nitrate test to determine if additional nitrogen is needed and how much.  The sampling is rather tedious, but the results are always interesting.  This is a good test to determine nitrogen losses from fall or early spring applications.  It is also a good test to determine additional nitrogen needed after manure application. Samples were pulled early and spread out on my picnic table to dry today.  It was perfect weather for drying. 

I worked in Witt area and Staunton area today.  Fields are still wet.  Not much happening in the world of field work.  One customer was spraying non-GMO corn for insects.  I found a number of pests in the field.  Cutworms and corn rootworm beetles among them.
