How do current recommendations on drainage depth and spacing influence nutrient loss, crop productivity and nutrient utilization?
Can drainage depth and spacing be optimized to minimize the nutrient losses and maximize crop production?
What Effect does Nitrogen Placement have on Nutrient Uptake and Yield?
This study supports the premise that concentrating N fertilizer below ground near the crop row can increase grain yield and N removal.
DNRA – what the heck is that?
Dissimilatory Nitrate Reduction to Ammonium (DNRA) is also known as nitrate ammonification and is the result of anaerobic respiration. In this process microbes oxidize organic matter and use nitrate (rather
than oxygen) as an electron acceptor, reducing it to nitrite – then ammonium (as opposed to nitrogen gas – as in denitrification). Get a simple explanation to better understand how this can help farmers manage nutrients. Click her to download the flyer.
Updated iOS MRTN Calculator now available
The app version of the Illinois MRTN (Maximum Return to Nitrogen) Rate Calculator has recently been updated with current research values from research conducted under the direction of Dr. Emerson Nafziger and with the on-farm work of Illinois Fertilizer & Chemical Association.
The update also supports new iOS versions and improves usability.
You can download/update the app from the Apple App Store by searching for MRTN Rate Calculator or by clicking this link.
For help in using the app – see these instructions: MRTN Apple App instructions
