II. Annual Row Crop Systems
A. Strips of high residue producing crops will be' grown in alternate
strips with erosion susceptible crops. Strips will be approximately
perpendicular to the prevailing wind direction.
B. Width and spacing of protective strips:
1 . Row Crop Plants - Minimum width of protective strips will be the
equivalent width of 4 rows spaced 40 inches apart. Spacing
between strips will not exceed 30 feet .
2. Drilled Plants — Minimum width of protective strips will be two
rows (12" — 20" spacing) and the spacing between strips will not
exceed 30 feet .
C. The protective crop will be harvested with a combine or mowed leaving
the stubble 12 to 18 inches tall . The protective residue will be
left on the soil surface through the critical wind erosion season
(Nov—May) or until the seedbed is prepared for the following crop
which is expected to occur in early April. Spring seedbed
preparation should result in a ridged surface for wind erosion
protection.
III. Perennial Tall Grass Barriers
A. Only tall growing species such as tall wheatgrass , swi.tchgrass , big
bluest em, sand blues tern, Basin wild rye and Indiangrass will be
planted. Range site descriptions and Critical Area Planting
specifications will be used to determine specie adaptation.
3 . Seedbed preparation will consist of only those operations necessary
to assure a firm soil condition relatively free of weeds . Planting
in residue from a previous crop is acceptable.
C. Colorado Agronomy Note No. 61 will be used to determine amounts of
seed to plant.
D. Barriers shall consist of at least two rows of grass spaced .10-40
inches apart as a minimum.
E . Optimum barrier spacing will he determined using the Guide for Wind
Erosion Control and will be designed as close to this optimum as
possible considering equipment widths .
F. Weed control will be practiced as needed to control competition until
grass is well established.
C. Barriers will be periodically mowed or clipped to a minimum height of
8-10 inches to encourage regrowth and prevent decadent stands `from
developing.

c. Contact herbicide plus Bladex, Igran or other short residual
(45-60 days) may be used for spring application to eliminate
early spring and early summer tillage. Limit summer tillage
operations.
d. 2-4D Butyl Ester plus atrazine or a short residual triazine is
an economical alternative if approximately 90% of the fall weeds
are broadleaf. Limit summer tillage operations.
E. For no-till systems:
1. Conventional tillage operations will not be used to control volun-
teer crop growth or annual f.orbs and grasses. On soils with a heavy
clay or silty surface that tend to seal, a light crust breaking may
be needed using sweeps or a chisel using straight shanks.
a. Wheat-fallow (chemical only) - Use of chemicals to eliminate
tillage operations. The following is required:
(1) Contact herbicides, such as Paraquat or Roundup, plus
atrazine or residual and tank mixes such as atrazine-Bladex
and atrazine-Igran shall he applied immediately following
harvest to kill existing weeds and give long—term weed
control.
V (2) A short residual herbicide may be used for spring applica—
tion if necessary to control weeds to substitute for
tillage operations normally used.
(3) A slot or no—till planter or grain drill shall be used that
will disturb not more than 25% of the soil surface.
b. Corn, sorghum, and small grains (chemical only). Use of chemi—
cals to eliminate tillage operations in irrigated cropland or
annual cropping systems. The following is required:
(1) A contact herbicide plus Bladex, Igran or other short
residual (45-60 days) may be used for spring application if
needed to control weeds to eliminate early spring and early
summer tillage.
(2) A slot or no-till planter or adequate grain drill shall be
used that will disturb not more than 25% of the soil
surface.
(3) Atrazine may he used in a wheat-sorghum-fallow or a wheat-
corn-fallow sequence.
F. Farmers must be made aware of the hazards involved in using residual

329-4-Conservation Tillage System
1 . Caution must be exercised in use of atrazine on soils with a pH of
7 .5 or higher.
2 . Caution should be taken when applying long residual herbicides
annually so no overlap or carry-over effect of chemical occurs.
3 . A minimum of 20 gallons of water, preferably 30, will be needed to
get adequate coverage of chemical.
4 . For more uniform application, large volume sprayers with wide stable
boom coverage are preferred over small units with narrow coverage.
The wider swath should result in fewer overlaps or skips. Dust
should be held to a minimum as it deactivates some herbicides .
Nozzle spacing should not be greater than 40 inches for uniform
distribution.
G. Specific chemical recommendations shall be in accordance with container
labels and/or Colorado Weed Control Handbook.
Trade names were used in this standard only to make the information more
understandable. This does not imply endorsement of certain products or
