Maximize yield potential by minimizing nitrogen loss

With fall fertilizer application around the corner, how much of your nitrogen will still be there in spring when the plants need it?

There are three main types of nitrogen loss, explains Jason Smith with Corteva AgriScience: volatile loss (gassing off the field as its applied), leaching (nitrates moved out of the root zone), and denitrification loss (nitrates converting into nitrogen gas and escaping into the atmosphere).

Leaching and denitrification are much more likely to happen after nitrogen sources convert to the nitrate form (NO3-).

“eNtrench and N-Serve are what we call nitrification inhibitors, and what they do is they inhibit the bacteria that do that conversion (to nitrate), and really significantly slow down that conversion process,” he says.

When N-Serve or eNtrench are applied with a nitrogen fertilizer, more of the fertilizer will stay in ammonium form for a longer time, which will be more available to the plant and more stable for a longer period of time; it stays where intended, and isn’t prone to loss.

Over 30 years of U.S. and Canadian data show that on average 21% more nitrogen is available in the root zone where plants need it most. This results, on average, in 8.1% higher canola yields, 5.8% higher wheat yields and 7% higher corn yields, while also reducing emissions into the atmosphere.

As an extra incentive, the first 75 growers who purchase a Raven Sidekick and at least one tote of N-Serve for fall 2018 will receive 16 bags of Brevant™ seeds canola hybrids or Pioneer® brand D-Series canola hybrids free, plus they can receive up to $10,000 (or 70%) back on the cost of the Raven Sidekick through the Technology Adoption Program.

Jason Smith explains how nitrogen loss occurs and the science behind N-Serve and eNtrench, as heard on RealAg Radio this past week:




Wheat prices jump into August — This week in the grain markets

This week, winter wheat prices touched a three-year high, but it didn’t last. Chicago SRW wheat prices for September 2018 gained 5 per cent or about 26 cents US/bushel to close at $5.56. While the December 2018 contract was up 5.4 percent — or nearly 30 cents — to finish a tad under $5.80. In…Read more »
