Species and their adaptability pertain only to BLM lands in the San <br />Luis kesource Area. <br />lI. Seed Mix - Over 8600' Elevation: <br />A. Same factors as I. above differing only in that the species are <br />adapted to a higher elevation and greater moisture regime. <br />III. Drilling Sped: <br />A. Drill with two boxes to separate chaffy from fine seeds. Frefer a <br />rangeland disc drill. The CRP Program at SCS has, however, brought <br />about some new equipment. <br />B. Prefer drilling over broadcasting. Placement of the seed is <br />ertremely important and hating polyacrylamide with it makes <br />placement with a drill paramount. <br />IV. Plulch and I•Ioisture Relations: <br />A. Using straw has too many problems and is very costly, brings in <br />weeds, is very time consuming (purchase, delivery to site, handling <br />on site, chopping and spreading is time consuming and very <br />dangerous, crimping, etc.) decomposers, microbes and microfanna, tie <br />up nutrients needed by growing vegetation, soaked straw ties up <br />moisture, decomposition by products often form hard pan situations <br />when the slime dries, etc. <br />B. Polyacrylamide is recommended at 80 pounds per acre, however it is <br />applied, by those who Sall it. Placement, again, is paramount and <br />greatly lessens the quantity required. The 10 pound broadcast <br />amount with fertilizer will help trap the occasional convection <br />showers, take up dissolved nutrients, and readily release moisture <br />and nutrient to plant roots, even the sprouts. The 5 pounds drilled <br />quantity will do the same thing, only it is immediately with the <br />germinating plant seeds. Both placements will help to Y.eep the <br />subsoil's and tcpsoil's moisture "together". The minimum rate is <br />fifteen (15) pounds, but up to eighty (80) pounds would be welcomed <br />if anyone wants to pay the price. <br />C. Growing a cover crop takes a season and may waste soil moisture here <br />in our dry land areas. k~orks great on farmland going into CRP. <br />WorY,s good in late summer plantings as long as annuals are used, <br />which will die in the fall frosts, revegetation drilling would occur <br />the following spring. Doesn`t replace any other practice, just <br />helps stabilize the environment temporarily. <br />y. Fertilizer: <br />A. Use of a Prell fertilizer is tremendously better than a crystalline <br />batch mix. Each Prell size has a homogenous nutrient content, equal <br />-22- <br />
