Wile e coyote - 1/13/2019 20:10 Been using AMS broadcast ahead of both corn and beans to obtain my sulfer source. Don't mind using ahead of corn because of getting cheap stable form of N. Usually broadcast 125 lbs of AMS along with any P and K requirements ahead of planter. I use no row starter on the planter. For beans will use 75 lbs AMS and 125 lbs of K20 and no-till the beans. Have seen several people talk about elementary sulfer. My crop consultant says it takes a long time to break down and requires a ph of 7.0 and above to help the process along. I'm in south central Indiana and we try to keep our ph levels in the 6.5 to 6.8 range. Our rainfall will average 40-45 inches per year. I know it is hard to "store" sulfer due to leaching. I don't believe the N in the AMS is really helping the beans when put on ahead of the planter. Just looking for opinions on the best way to get sulfer to the corn and bean plants. Has little or nothing to do with pH. It's a microbial process. If the elemental S is micronized, it takes about 4 - 6 wks to get half of it converted to sulfate in the Corn Belt. It's nice to not have it all as sulfate right away, as it can then be lost to leaching. You just have to plan ahead (put it on early enough that you have sulfate conversion when you need it). More of a problem on the arid Great Plains than the wetter regions. |
