I have a customer that has been broadcasting 80lbs of 21-0-0-24 (20lbs actual Sulfur), Ammonium Sulfate, on top of his beans for years with good yield results over not applying anything. Cost this year is about $18/19 acre, for a 5-8 bu possible yield advantage. His ground is light, CEC of 5-6, OM at about 1.2-1.5.
Anyone else do anything over the top, to boost bean yields on your ground, that is cost effective?
I did 75# of ams and urea in a 50/50 mix at pod fill and saw 8 bushels. last year I tried it again but we just didn't have enough heat or sun to utilize it.
on spots that had 150# was equal to check, 250# was less yield then check and the beans started turning a couple weeks ahead of the check.
I am going to keep trying some plots to see if we can start to see a pattern. I have a dry bander so this year I am going to try to band some P K and some treated N in beans to see what happens.
for beans I wouldn't put anything down early, in our soils it pays to put it on when the plant needs it and that is at pod fill.
for corn I stopped putting any S or N down ahead of the planter. put it down today and get a week of rain and cold saturating the soil, it could be a month before the plant is looking for that product and by then its long gone. or it gets late and you end up putting beans in that field.
