Water management and securing good condition of soil is becoming an important
factor in agriculture one of the reasons being adaptation to the increasingly frequent extremes in
weather. Tied ridging technology enables to reduce significantly the loss of water and soil from
arable land. The effect of a tied ridger mounted on 2-row planter and effect of 6-row tied ridger
on basin renewal was tested in potato cultivation on plots of land with length of 10 m. During
entire season lasting 135 days the technology helped achieve 78% of efficiency in reduction of
surface water runoff and 88% of efficiency in case of soil loss. In the case of furrows with only
tied ridging the water retained represented additional 15% of total water from rainfall (37.5 mm
of 250 mm) over untreated furrows. In the case of basins formed in furrows with wheel trails the
water retained represented 15% of total water from rainfalls in the trail. This water retained on
the land would have otherwise flown off and would not have been utilized without this
technology. The renewal of dams after 1/3 of the season increased significantly the efficiency of
this technology. The technology of tied ridging significantly contributes to sustainable agriculture management.
