Seeding into strips that are less loaded with residues can also be achieved by
inter-row sowing
.
This method relies on placing the seeds in furrows that are located
precisely between the stubble rows of the previous crop (Fig.
8.12
). A prerequisite
for this is that subsequent crops either have the same- or multiple row widths. Precise
seed placement is obtained by using machinery guidance via a global positioning
system with real-time kinematic corrections (RTK-GPS). The positioning control is
arranged in such a way that year after year the rows of the previous crop can be
