ND Crop Nitrogen Calculator available for free download from NDSU
Apps for the N calculators for spring wheat, corn and sunflower are now available in Android and IPhone format. Go to the app store on your phone and search for ‘North Dakota Crop Nitrogen Calculator’. Download for free.
I have also updated my website (well, not me, but my excellent support people have updated it) and the revision of the N additives circular is available in my extension publications as well as on the Iowa State non-conventional amendments link search engine.
