MIN TILL TILL
Tarping beds, without tilling before and with minimum tillage after
(MT), reduced tillage by 82%.
Tillage before tarping (TT) reduced tillage by 39%.
P<0.01
RESULTS: Tillage
All greens grew faster when soil was managed with tarps and
minimum tillage (MT).
There was no difference in growth of greens when soil was tilled
before tarping (TT).
RESULTS: Crop Growth
