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.
