With the rise of herbicide resistant weeds not just on the horizon but in your fields, farmers want answers. Most have turned to a new herbicide in the past.<\/p>\n He referenced a quote from Dr. Dwayne Beck, manager of the Dakota Lakes Research Farm. Beck presented during a recent soil health workshop hosted by South Dakota Soil Health Coalition.<\/p>\n “Anytime producers do the same thing year after year the Earth’s ecosystem finds a way around it to make it more diverse” said Beck during the September meeting attended by farmers, ranchers and area agronomy professionals.<\/p>\n Without this diversity, Beck further explained that monoculture farming will give way to a possible proliferation of curtain weed species.<\/p>\n “This means a potential increase in weed species anytime monoculture crops are planted,” Shaffer explained.<\/p>\n Shaffer said many options are still within the hands of producers to control weeds with herbicides however, he explained that 100% herbicide dependence is not sustainable in the long term. Particularly with the products available in the market today.<\/p>\n “Herbicides were meant to be just a tool for weed control not the answer to weed control,” he said.<\/p>\n More Weed Control Options<\/strong><\/p>\n Some of the weed control options discussed during the soil health school which did not include spraying herbicides or tillage included; crop rotation, cover crops and livestock integration.<\/p>\n “These options help build soil health by increasing organic matter, soil biology and water infiltration,” Shaffer said.<\/p>\n He outlined the principals of soil health:<\/p>\n Shaffer explains each principal below.<\/p>\n Armor on soil surface:<\/strong>\u00a0If there is armor on the soil surface, such as organic matter or a cover crop, then weed seed germination and competition will be limited.<\/p>\n Very limited soil disturbance:<\/strong>\u00a0With increased soil disturbance (including any tillage) Shaffer explained, comes more weeds, colder soils and dryer soils than in long term no-till fields.<\/p>\n Livestock integration:<\/strong>\u00a0Livestock integration can elevate the need for pasture, but can increase soil health and decrease weeds in your operation through grazing at the proper time in your rotation.<\/p>\n Plant diversity:<\/strong>\u00a0Crop rotation of many monoculture crops with integration of cover crops can be the best way to deal with weeds, especially herbicide resistant weeds.<\/p>\n “Finding the right crop or cover crop to compete with a curtain weed is the best option available instead of always reaching for that herbicide in your barn,” Shaffer said. “Each producer must customize their rotation to fit their local ecosystem.”<\/p>\n Crop rotations change, but the principles do not, Shaffer said. The top principles of crop rotation include:<\/p>\n For more information about crop rotation benefits visit the Dakota Lakes Research Farm\u00a0website<\/a><\/span>\u00a0and under the publication tab read t<\/span>he article: Managing Agricultural Ecosystems by Dwayne Beck Ph.D. [fusion_builder_container hundred_percent=”yes” overflow=”visible”][fusion_builder_row][fusion_builder_column type=”1_1″ background_position=”left top” background_color=”” border_size=”” border_color=”” border_style=”solid” spacing=”yes” background_image=”” background_repeat=”no-repeat” padding=”” margin_top=”0px” margin_bottom=”0px” class=”” id=”” animation_type=”” animation_speed=”0.3″ animation_direction=”left” hide_on_mobile=”no” center_content=”no” min_height=”none”][Emphasis added]<\/p>\n
