Harvest and tillage operations are acknowledged to have an ecosystem impact
through their disruption of the soil and they thereby generate dust particulates. A
multi-year project was undertaken to study the particulates that are generated in the
mandated cotton stalk plowdown in Arizona. The primary focus of this study is on
the amount of dust particulates generated by each of three minimum tillage/controlled
traffic systems and a conventional tillage system. The dust plumes arising behind
each implement associated with the plowdown tillage systems are sampled for
quantity and quality. Additional aspects of this study are to compare cotton yields
over several years for the four plowdown methods as well as to compare their
