Strips will run approximately perpendicular to the prevailing wind direction. C. Maximum Strip Widths (narrower strips provide better protection and require less protective cover) . 1. 0-2% slope, 660 feet widths 2. 2-5% slope, 330 feet widths 3. 5% or greater slope, 165 feet widths :o 0975 RI:::C 01900947 i i0/02 00 : :26 $0 ..00 6/032 I 088E MARY ANN I::I:: .1ERS4EIN Li ERK & RECORDER WELD CO, CO 2 D. Wheat stubble in the protective strips will be left standing through the critical erosion period. (Nov. through May) . E. A minimum of 35011 of residue will be left on the soil surface after planting for soils in WEC's 1, 2, 3 & 4. If the Guide for Wind Erosion Control or Technical Note #53 indicate larger amounts are needed, then those amounts should be left on the surface after planting. II. Annual Row Crop Systems A. Strips of high residue producing crops will be grown in alter- nate 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, Switchgrass and Indiangrass will be planted. Range site descriptions or Critical Area Planting specifications will be used to deter- mine specie adaptation. B. 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. Seeding rate specifications 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. 3 E. Barrier spacing will not exceed 60 feet. The barriers will be approximately perpendicular to the prevailing wind direc- tion. Barriers will be deferred from grazing on a year-round basis. F. Weed control will be practiced as needed to control competition until grass is well established. 7 i -- '': Ci w in cc 7.30 C.) 01 900947 I'' 0886i°iEC ANN I-1.?a.lE::fi08 'N'{'y..il:':RKtt : .{6 $0. 00 LB/032 & RECORDER WELD 4:;{:3, CO UNITED STATES DEPARTMENT OF AGRICULTURE tea•+' Soil Conservation Service Colorado STANDARDS AND SPECIFICATIONS PROPER GRAZING USE (Ac. ) 528 Standard Definition Grazing at an intensity which will maintain enough cover to protect the soil and maintain or improve the quantity and quality of desirable vegetation. 11 ose To: (1) Increase the vigor and reproduction of key plants; (2) accumulate litter and mulch necessary to conserve soil and water; (3) improve or maintain condition of the vegetation; (4) increase forage production; (5) maintain natural beauty; and (6) reduce the fire hazard on forest land. h ,, Where applicable On all rangeland, native pasture, grazable woodland, and grazed wild- life land.

Season of Use: Enter in this column the season that unit will be grazed such as: Fall, Winter, Spring, Summer, or by months: September-October, November-March, May-July, etc. sf a planned grazing system such as a rotation-deferred ystem is planned, prepare specifications for Proper Grazing Use for each pasture and season in the system. e. Location of Key Grazing Area: Enter in this column a des- cription of the key grazing area. This may be a range site or it may be a portion of a site or it might be a particular location within the grazing unit such as: S-W portion of `" y grazing unit starting about 200 yards from pond to fence. The Key Grazing Area on which to judge the degree of grazing use will be one which (1) provides a significant amount but not necessarily, the majority, of the. available forage within a pasture; (2) is easily grazed because of topography, acces- sible to water, and other favorable grazing distribution fac- tors. Except for small areas of natural livestock concentration within each pasture, such as those around water or salt, key grazing areas are those most likely to be overgrazed when not properly managed; (3) generally consists of a single range site or portion thereof; (4) is usually a single range con- dition but may include more than one. A pasture usually needs only one key grazing area except in some unusually large pastures or in pastures where more than one species of animal is grazing at the same time, or where a pasture is grazed at different seasons. In large pastures (generally 640 acres or more in size) where the key grazing area is on a portion of an extensive range site, the key grazing area will be shown on the Conservation Plan Map with the words Kev Area and outlined by a broken line. An understanding of key areas and key species by the cooperator can best be developed when he participates in ranch conserva- tion planning. f.

There may be occasion when you will select two species, in this case enter the name of both species. (1) Key plant(s) selected should: (a) have a relatively high grazing preference by the kind of animal grazing the pasture for the season of use concerned, as compared with other associated plants within the key grazing area. (Exclude so-called ice cream plants) . They should provide more than 15% of the readily available forage in the key grazing area. When the management objective is based on the increase of a species which is currently providing less than 15% of the available forage but which has the potential for a significant increase in produc- tion, it may be used as the key species. (b) be a major component of the climax plant community, if the major objective is to maintain or improve the plant community to a relatively high ecological con- dition. (c) be a perennial, except where the grazing is to be specifically for the perpetuation of annuals of good forage value. g. Planned Use of Key Species at End of Grazing Period: Enter . in this column the percent by weight of the current year's growth of the key species that should be left ungrazed at the end of the grazing season. Except blue grama which will be specified in pounds per acre for LRAs 67, 69 and 72. (See Blue grama supplement par. g. ) h. Estimated Use of Key Species by Weight : Enter in this column by calendar year the estimate of the actual use the grazing unit received. This estimate is based on the key species on the key grazing area, at or near the end of the grazing period or on year-long grazing just prior to the next growing season. If SCS-Range-414 states percent by weight of current year's growth to be left ungrazed at the end of the grazing season, enter percentage of growth actually left ungrazed. If use is specified in amount of forage to be left ungrazed in pounds per acre then enter pounds per acre left ungrazed. Actual use estimates are more meaningful when made jointly by the cooperator and conservationist. 3. Degree of Use • a.

This would be from April ls[ to October 30. b. Under a planned grazing system where grazing occurs during the dormant season grazing 60 percent of the annual growth by weight of the key species would be permissible with con- currence of the District Conservationist. Under no circum- stances must this use contribute to site deterioration. The date of dormancy will be November 1 through February 28. c. On slopes over 30%, allowable use will decrease by 10% for each 10% increase in slope. d. On browse species annual growth of twigs and leaves within reach of animals will not exceed 65% of the current year's growth. e. Where management species are used in lieu of key species on annual vegetation, the degree of use will be designated by the District Conservationist and will be compatible with the management objective and will not contribute to soil erosion or contribute to depletion of the range resource. f. For seeded introduced species, see Standards and Specifica- 171,4, tions for Pasture and Hayland Management (Code 510) for proper grazing use of these species. d'! g. "Blue grama supplement" lJ (1) Applicability - Proper grazing use specifications shall be based upon a prescribed amount in pounds per acre (air-dry) of blue grama to be left at the end of the grazing season on key grazing areas of pasture on which: (a) blue grama dominates the present plant cover; (b) blue grama is the key species; (c) the management objective is to maintain or improve the production of blue grama; or (d) blue grams in combination with buffalo grass pro- duces 75% or more of the forage. For this to apply, the percent composition of buffalo grass must be in the 30-40% range and blue grama in the 50% or greater amount.

(b) Minimum pounds (air-dry) per acre of blue grama which are to be left at the end of the grazing season are, for applicable range sites: Land Resource Area No. 69 -- 350 pounds/Ac Land Resource Area No. 67 -- 350 pounds/Ac Land Resource Area No. 72 -- 400 pounds/Ac (c) Pounds/Ac remaining are to be specified under Planned Use of Key Species on the form SCS-414. To make this clearly understood and separate from percent of use asterisk (*) or footnote (1/) with the statement written on the bottom of the form - Pounds per acre (air-dry) of blue grama to remain at the end of the grazing season. (d) Determination of compliance with the practice shall be at the end of the planned grazing season when grazing is a planned system and shortly before the beginning of a new growing season on pastures grazed on a continuous, year-long basis. 4. Application of Practice a. Management checks should be made half to two-thirds of the way through the grazing period to determine degree of use to provide time to make needed adjustments in grazing systems. The decisionmaker should assist in this determination. b. Any significant change in management (class of livestock, season of use, water development, etc.) may affect the grazing pattern in a unit. As a result, a new key area or key species or both may need to be selected. 1/I). N. Ryder, R.E. Bement, E.E. Remmenga, and D.F.

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 1000# 20" - 40" rows 3. Grain sorghum on 150011 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.
