C. Planning Considerations
C. ni
1 . Subsurface tillage equipment such as sweeps, blades and
rodweeders should be used for most tillage operations.
2. Chemical weed control to reduce the number of tillage operations
is beneficial in managing the residue.
3. Reducing field widths is an effective way to reduce the need for
large amounts of crop residue.
4. When inadequate residue is produced the soil surface will be
ridged by chiseling or listing.
II. Non-Irrigated Sorghums
A. Pounds of residue required through the critical wind erosion period
(November-May).
Minimun Required
Crop and Spacing Residue
1. Drilled sorghums on row 75011
spacing of 20" or less
2. Forage sorghum on 100011
20" - 40" rows
3. Grain sorghum on 1500#
20" - 40" rows
When the above residue requirements are met, the practice will be considered
adequate to hold the soil loss to the acceptable "T" level.
B. Planning Considerations
1 . The above amounts of residue will be left on the soil surface
through May or until spring seedbed preparation which usually
occurs in early April. Spring seedbed preparation should result
in a ridged surface for wind erosion protection.
2. When inadequate residue is produced the soil surface will be
ridged by chiseling or listing. Soils coarser than sandy loam
usually require listing to provide satisfactory surface
roughness.
3. Grazing will be restricted on machine harvested crops when
marginal amounts of residue are produced.

1 & 2 1500 2500
3 & 4 1000 1750
5, 6 & 7 750 1000
B. Critical Erosion Periods (Modified for Necessary tillage)
1. W.E.G. 's 1&2 Sprinkler Irrigated - Maintain the required amounts
of residue until the planted crop has enough growth to protect
the soil.
2. Gravity Irrigated Row Crops - Maintain the required amounts of
residue as long as feasible after harvest. The cropping system
and method of irrigation are to be considered. If fall plowing
destroys the residue, the field will be left rough and cloddy
until spring seedbed preparation, (about March 1st as a
minimum).

PLANNING AND APPLICATION RECORD
FOR STUBBLE MULCHING
Field Number or Name-Field designation as shown on the Conservation Plan Map.
Acres-From the Conservation Plan Map.
Soil of Major Hazard-The major soil of the field, or the soil of greatest hazard if it is more
significant to the field than the major soil.
Wind Erodibility Soil Group (WEG)-Determined by soils from Guide for Determining Adequate
Wind Erosion Control Systems (Guide) for the Work Unit or County location of the field.
Width of Exposure-The furthest distance the prevailing wind travels over the vulnerable part
of the field.
Specifications-Determined by use of appropriate Soil Loss tables from the Guide. This is
determined in pounds of flat small grain residue equivalent. (If crops other than small
grains are grown, this figure must be converted to the grown crop by use of the Chart
to Determine the Amount of Residue of Various Crops Needed to Equal a Given Amount
of Flat Small Grain Stubble from the Guide.)
Application-This becomes a record by years of each field at planting time, or other appropriate
time such as the late fall when new growth has reached its maximum before going dor-
•
mant for the winter. Enter the amount of all residues on the soil surface, whether
fallowed or tilled, or of stubble standing from the previous crop. This should be con-
verted to flat small grain stubble equivalent. If a part of a field is cropped and the
remainder is fallowed, residue amounts should be entered from both areas.
