We are assessing the quantity and timing of nitrogen availability from Fixation Balansa Clover at three termination times using four termination methods, on two soil types, and in each of two climates. Follow this hashtag on social media to see study updates ~> #FIXatioNNTiming

  • At each termination time the total biomass and C:N ratio of Fixation will be measured.
  • At each time point the Fixation will be terminated using either glyphosate, tillage, crimping, or grazing.
  • Intact soil core samples will be taken at each termination time within each termination method for a five-week laboratory incubation where we will measure carbon and nitrogen mineralization to determine how those management decisions influence the timing and quantity of nitrogen that is made plant available.
  • After termination, corn will be planted with no fertilizer added to assess nitrogen uptake timing and rate.
  • Throughout the growing seasons drone footage will be taken to aid in the database development to create a biomass index.
  • At one location greenhouse gas measurements will be taken every two weeks to assess the C and N balance in the field.
  • This trial is replicated at Oregon State in Corvallis, at GO Seed in Salem, at one site in Indiana, and one in Illinois.

This is a LI-COR Trace Gas Analyzer. 

We’re using it to assess nitrous oxide lost to the environment while also quantifying the timing of nitrogen availability from Fixation Balansa Clover at 3 termination times using 4 termination methods, on 2 soil types, in 2 climates.

LI-COR Gas Analyzer rings are set into the soil at the beginning of the season so the smart chamber can sit on top and measure the gas flux.
