Southern Plains...
Pre-Planning (fall-seeded)
 Identify acres for fall-seeded crop
production
Evaluate residue cover
Evaluate weeds, especially
perennials
Manage old-growth residue by
mowing, flailing or burning,
 March to May (as permitted).
Summer Burndown - 1997
Warm-Season Grasses
 Allow 6-8 inches regrowth
Apply Roundup Ultra at 64 oz/A
after July 1 or
V-blade or disk to manage residue
and prepare seedbed (plowing is
also an option but it can cost the
loss of years of profitable organic
matter buildup)
Fallow Option
 If insufficient moisture, summer
fallow acres
Consider minimum-till sorghum in
spring of '98 (see below).
Fall Burndown - 1997
 Apply Roundup Ultra at 32 oz/A
in August-September for escape
grass and weeds or redisk if disk
is
used to prepare seedbed.
Seed winter wheat after October 1
using a no-till or high residue drill
with fertilizer attachment.
Spring/Summer - 1998
 Develop a crop rotation and
residue management plan.
Minimum-till Sorghum (spring-seeded)
In 1997...
 Mow or control burn old CRP
residue from April to May '97.
Allow 6-8 inches of new growth
Apply Roundup Ultra at 64 oz/A
after July 1 to early September
(when plants are actively growing)
