2019 Farm Trial Program Results

Iowa growers increase corn yields by an average of 9 bu/ac when using N fixing Envita™

ISA Logo

Two independent corn trials with the Iowa Soybean Association validate previous findings showing how Envita offers season-long N fixation when applied with a recommended nitrogen fertility programs, increases corn yield. 

Pottawattamie County, Iowa (corn)

The first corn trial was conducted in Pottawattamie County, Iowa, on corn, following soybean rotation. Rainfall in the area was above average from March to September and the yield results showed an increase of 12 bushels/ac on plants treated with Envita.


Washington County, Iowa (corn)

The second trial was conducted in Washington County, Iowa. The corn treated with Envita demonstrated an average increase of 7 bushels/ac. The treated corn was in the ground following previous soybean harvest in an area which also demonstrated above average rainfall.


North Dakota trials demonstrate 11.7 bu/ac (6 %) yield increase with Envita

Trials conducted in partnership with Yield Master Solutions, and Legend Seeds continue to demonstrate increased yield when Envita is applied with recommended nitrogen fertility programs.


Trial #1 - New Salem, North Dakota (corn)

2019 Foliar Application Trials

We continue to develop this technology and find ways to improve access, ease of use and efficacy. Recognizing in-furrow applications are not used on the majority of the corn acres in the US, we are in the early stages of developing a foliar treatment. Recent studies have shown that Envita when applied as a foliar treatment - can successfully colonize in corn, soybeans and wheat. However to achieve this - a much higher concentration of Envita is required as compared to the in-furrow concentration.

Over the 2019 growing season, Azotic North America partnered with growers to conduct early field scale foliar trials. Early results indicate positive yield response vs. control, however, we will not have a foliar product available for the 2020 growing season. Sign up for our newsletter to receive updates about new product information and trial results.
