Video: How and where to take a PSNT Test
Which fields are good candidates for this test? Corn fields that have a history of manure, as well as fields that maybe have a previous legume, and it's a great tool for the cover crops to be able to detect if nitrogen is going to be immobilized. When should we be taking these samples? You could think about four to six weeks after planting, and you could think about your vegetative stages from V3 to V5.
