Summary
Abstract: The site was in native short-grass prairie until 1969. The prairie was
grazed by cattle and wildlife. Soil parent material is alluvium mixed
with aeolian deposits. It has been cropland now for 25 years. The
current land use and treatments are Winter wheat-fallow rotation,
Treatments are no-till, stubble mulch tillage and moldboard plow
tillage. There are at least 3 replicates in the experiment. ... View entire text

GROUND-BASED OBSERVATIONS Ancillary Description
Quality There are at least 3 replicates in the experiment. The experiment has
a randomized plot design. There are control plots described as
follows: Native sod plots serve as the controls. These plots have not
been grazed so plant composition has changed. Staff recently
implemented a 5 year burn schedule to return the plots
to a more native state.

Multiple peer reviewed publications have resulted from this study and
the quality is considered to be very good.
Access Constraints none
