| Any of you guys that are using OptRx--what are your impressions of it? I would be using it on winter wheat and sorghum. What are you seeing for benefits and returns by using it? On wheat, what is the earliest that you can use it to assess N needs--just after green up, or do you need to wait longer--jointing? 2 joints present, flag leaf? What about sorghum, would it work reliably at sidedress, or would it require its own separate pass later in the season? Thanks | |
