STRAIGHT TALK ON CROP RESIDUE MANAGEMENT
To convert crop residue into soil-building humus, soil microbes must decompose the residue. The decomposition process requires the crop residue to be incorporated into the top layer of soil, ground moisture must be present, the soil must be warm and the microbes must have a supply of oxygen. When any of these elements are missing or are in short supply, the decomposition process will not proceed properly.
Sunflower has a longstanding world-wide reputation for building solid, reliable disc-based and sweep-based tillage solutions. Some companies have moved decidedly in the direction of low disc concavity in favor of vertical tillage while somehow claiming all the benefits of mixing. However, remember that Sunflower tools not only manage compaction, but also remain fully capable of achieving desired mixing and incorporation levels regardless of your yields and residue type.
Sunflower tools are designed to operate properly with a wide "window" of capability between four-and-a-half and six-and-a-half miles an hour. All Sunflower tools you use feature a wide range of built-in adjustability, with top-notch dealer support to satisfy you year-in, year-out. To sum up, choose the best solution after combining your local experience with the latest scientific discoveries--and a willingness to modify your management while your seed choices and other factors continue to change.
