For farmers who are transitioning into organics a big concern is weeds. Lets talk about three options for organic weed control besides tillage.

Organics: Machinery Innovations for Organic Weed Control

For farmers who are transitioning into organics from conventional farming, their number one concern is likely weeds. Since herbicides are prohibited under the National Organic Program, organic farmers have historically managed their weeds with tillage.

Throughout this year’s sustainable and organic meetings, there was a lot of discussion about different options for organic weed control other than tillage. Today we are going to talk about three options. If you haven’t heard of these options before, they’re each worth more exploration; as more research and innovation seeks to solve weed challenges in organic production, this is an exciting time to be an organic or transitioning farmer who will benefit from these continued technological advancements.

Older – Organic No Till: Roller Crimping

While roller crimping is new to some people, it has been around the longest. A roller crimper is a farm attachment (Figure 1) where the blades break the stems of the plant while rolling the plants over to create a mat of residue over the field. This residue can then be planted into, and it acts like a weed barrier. The Rodale Institute in Pennsylvania, under Jeff Moyer, as well as Dr. Erin Silva at the University of Wisconsin, are two leading proponents performing research with this tool. Here is some yield data from Dr. Silva’s no-till research plots.

Newer: Flame Weeding

Professors at the University of Nebraska-Lincoln have done research on flame weeding to better understand it as a viable option for organic weed control. Flame weeding is a process of applying heat to kill plants. The research was presented at the American Society of Agronomy’s meeting in October 2017. Read the full overview article here:

Newest: Equipment Company to Develop Solutions for Organic No Till

This January, Dawn Equipment company CEO, Joe Bassett, announced that he is starting a new company, Underground Agriculture, to design equipment specifically for organic no till production. While the company is still very new, Underground Agriculture, is the nation’s first company that will be solely dedicated to manufacturing machinery to manage weeds in organics.


The future is bright for organic weed control when researchers like Dr. Erin Silva, industries like Dawn Equipment, and innovative farmers who are building their own tool bars and experimental equipment come together to share their successes and failures in order to develop best-practice strategies for organic weed control in row-crop systems.
