In 2016, after a long period of trial and error, I quite by chance tried out a “vibrating weeding broom” for weed control that uses a rake with thin, spring steel wires and was able to carry out continuous (down the row) early interplant weeding without damaging the crop.The weeding was successful using the vibrating weeding broom (VWB), and I named it hawking, after the Japanese-style broom called a hawki.
Crops (rice, wheat and other cereal grains, soybeans, maize and vegetables) are often planted in rows. The space between the rows is known as inter-row space. The spaces in between the crop plants in a row are called interplant spaces (see Figure 1).
Inter-row weeding is known as intertillage weeding. Since there are no crops growing in this space, weeding can be carried out quickly by moving forward or backward continuously with a hoe or other hand tool, or a machine.
On the other hand, in the interplant spaces the weeds and the crops are close to one another, so it would seem to be difficult to eliminate only the weeds by moving forward continuously with a machine without harming the crop.
For nearly 40 years as an organic farmer I was convinced that mechanization of interplant space weeding cannot be easily done and continued to weed between the plants using my hands or a triangular hoe. There are probably many farmers around the world who think and do the same. Continue Reading →
