DEPTH OF INSTALLATION
The active root zone of the crop determines the depth at
which to place the blocks. Type of crop, soil depth, and
state of growth should also be considered.
When seeds are first planted, irrigation is necessary to assure
quick and uniform seed germination. Visual inspection of
the soil near the seeds will indicate whether irrigation is
needed at that time. A minimum of two blocks per station
is recommended; one shallow, one deep. The table below
gives recommended depths for setting the blocks according
to soil depth or active root zone.
