Historically we would have our local co-op spread our acres with about 50 lbs of k 150 lbs of dap and 200 to 250 lbs of urea, and dig it in in front of the planter. we also run about 8 to 10 gal of 6-24-6 down with rebounders on the planter.
I do have dry fertilizer coulters I could mount back on my planter and band down the nitrogen i need, using an old concord air cart i have, but is this my best option? and if so do I stick with the rule of thumb of being 2 inches aside and 2 inches below the seed furrow, or should I be banding inbetween the rows? Instead of using urea, is using 28-0-0 liquid a better solution? Thanks!
I put part of my N on the fall with strip till anhydrous and the rest in the spring. Last year my custom fall strip till applicator had a screw up and missed four rows on N. I ended up rigging up stream nozzles for 32%N on 60 inch centers. With an inch of rain it appeared to work great. I liked the 60 inch spacing as by concentrating the application you get more of the UAN solution into the soil and have almost no possibility of volitization. I am thinking about doing all my side dressing with my sprayer this year.
In 2011 we got into an extremely wet situation. I am a pilot and flying around in August the only corn that was not yellow was the corn that had been side dressed in June although last year it probably wouldn't have mattered when the N went on although you need at least an inch of rain to get the N working.
