Sunflower equipment helps open the residue-management window.”The weather around Redwood Falls,Minnesota, can get pretty cold duringthe winter. That’s part of the reasonKen Felleson, who farms around1,000 acres of corn and soybeans inpartnership with his brother, Bob, likesto use a Sunflower 4511 disc chisel toget his primary tillage done in the fallbefore the snow flies. Not only doesthe 4511 size and bury much of thegrowing amount of residue, but thechisel helps break up soil compaction,allowing moisture to penetrate the soilprofile. Most important, it helps get thedecomposition process started alittle earlier.“We’re seeing a lot more trash in thefields than we used to,” Ken admits,noting that a lot of their corn consists ofRoundup Ready triple stacked varieties.“I don’t know that the stalks are anythicker or heavier, but there seem to bea lot more leaves and husks with thenew varieties. I’ve found, too, that itdepends on the brand more than it doesthe particular hybrid. If we can get overthe fields in the fall with the disc chisel,we can get a better handle on residuemanagement and start preparing thefield for spring.”Felleson realizes that the microbes thatbreak down residue are always mostaggressive right below the soil surfacewhere there’s a good mix of soil, air andmoisture. Unfortunately, those microbesgo dormant when the soil temperaturedrops to 40 degrees, which meansthe window closes pretty quickly inMinnesota.Felleson says their residue managementprogram starts with the use of apull-type stalk chopper shortly afterharvest. Weather permitting, they followwith the disc chisel at approximately sixmiles per hour a few days later.“It leaves a nice mix,” he says. “Whenyou look down from the tractor cab,you can see about 60 to 65 percentblack dirt. Once the buried residuedeteriorates over the winter and we hitit with the field cultivator and a crumblerattachment in the spring, it leaves anideal seedbed, which ultimately leads toa better stand and higher yields.“On the other hand, I think theSunflower disc chisel leaves the surfacea lot more level to begin with,” he adds.“I’ve seen the job other brands do inthe fall, and it seems the fields are alot more uneven. I know, too, that theSunflower does a better job when we’reworking in heavy soil or wet ground. Itmay pull harder, but it still does the job.”Ken says the key is to set the frontdiscs just deep enough to throw a littledirt, since the main function of theindividually mounted discs is to cut thestalks.“If you can get the front discs to throwenough dirt to hold the leaves andtrash in place, it seems the twist onthe shovels can do an even better jobof burying it,” Felleson says, noting thathe particularly likes the easily visibledepth gauges and the hydraulic frontand rear gangs, which allow him to varythe amount of residue that is buried.“And since there aren’t any spindles onthe front gangs, there’s nothing to stopresidue from moving through when it’sdesired,” he concludes. “I’m certainlyhappy with its performance.”GrowerKen FellesonLocationRedwood Falls, MinnesotaSituationResidue management inhigh-population stackedgeneticscornSoil ConditionBetter aeration and agood mix of black soiland residueTillage Tool UsedSunflower 4511 DiscChiselLearn more18 19on theWebwww.sunflowermfg.com
