Management of harvested crop residue is important in all types of cropping systems, but is especially crucial in direct (no-till) seeding. Excessive residue levels can result in delayed/uneven emergence, toolbars plugged with straw, uneven maturity and thin crop stands among other effects. In contrast, good residue management has many benefits to soil including reduced wind/water erosion, microclimate for emerging seedlings that allows for greater fertilizer efficiency and improved water infiltration.
There are many ways in which growers can manage fall crop residue with harvest… Read More »
