“What is the best way to get all your fertility down in a no-till corn situation, especially your P and K?” - Kyle Geske, a Farmer from Enderlin, North Dakota
Dr. Dave Franzen, an Extension Soil Specialist at North Dakota State University, joins us to answer Kyle’s question. Dr. Franzen has extensive experience in both research and retail agronomy. You may recognize him from Season one of Soil Sense Episode Three and Episode Four.
“It is really important in the northern plains, specifically in North Dakota, to use a starter at planting time, at least for the phosphate.” - Dr. Dave Franzen
Dr. Franzen has seen some significant yield increase in no-till corn operations that have employed a starter phosphate application. He shares that the weather for planting for a no-till operation results in cooler temperatures for those farmers. The additional phosphate will help support plants in the face of those cooler temperatures and lead to dramatic yield increases. He also highlights the need for additional nitrogen for the first 6 years of transition from a conventional till to no-till operation. There are 14 essential nutrients that the plants need, 10 of which we have effective testing for. Nitrate testing is probably the most valuable and most significant of all the values evaluated. He does caution any producer that is testing for Potassium. Potassium values change dramatically depending on the season so consistent testing at the same time every year is critical for evaluating potassium trends in the soil.
“And then the Sulfur Soil test. I know sometimes you get it as part of a soil test suite but it’s a horrible test and people shouldn’t even pay attention to it.” - Dr Dave Franzen
