Effects of soil compression after sowing using a shallow rototiller plus seeding machine capable of cutting small ditches
To support crop-rotation systems using rice, wheat, and soybean in paddy fields, we developed a sowing device that can be attached to a rototiller ; the device cuts small ditches on both sides of groups of rows of plants, while tilling to a depth of approximately 5cm, planting seeds, and compressing the soil around the seeds. This device includes a pressurized roller which compacts the soil with sowing, and we examined the effect of this compaction on germination rate after seeding.
