This may be caused by the lower wind erosion forces and the lower soil -ux in the windbreak trial.
Samples of 20 m2 were harvested separately from each millet row parallel to the windbreaks and divided into millet panicles and stover.
Similarly, soil chemical properties were evaluated over both lateral distance from windbreaks and at soil depths.
The present study did not focus on windbreak interactions with birds, pests or pathogens.
Bars are averages from three distances from the windbreak.
A mulch application reduced overall soil -ux by 51% in 1991, 49% in 1992 and 67% in 1993 across all windbreaks and the control.
No interaction between windbreak species and soil mulch was detected, except for millet survival in 1992.
The survival of millet in 1993 was generally higher than in 1992, but dierences among windbreak species were small.
