UNITED STATES DEPARTMENT OF AGRICULTURE <br />SOIL CONSERVATION SERVICE <br />356 Ranney Street <br />Craig, Colorado 81625 <br />r <br />0 <br />January 30, 1987 <br />L J <br />Bill Agnew, Environmental Engineer <br />Trapper Mine <br />Post Office Box 187 <br />Craig, Colorado 81626 <br />Mr. Agnew: <br />Included is our best estimate on what the average production is for <br />irrigated and non -irrigated hayland in Moffat County. I will give <br />you a range. <br />Production varies radically depending on what soil is present and <br />what species have been established on the site. Production also varies <br />on how long the vegetation has been there. We find instances where the <br />pasture land is still increasing in productionshas stabilized, or <br />actually is declining in production because it's been there too long. <br />Production is also a matter of good or poor. management. In the non- <br />irrigated situation we find vast fluctuations in production based on <br />the annual rainfall and when that rainfall actually occured. <br />Production is also a function of aspect. <br />Irrigated hay Alfalfa 2000 to 8000 pounds of annual production. <br />Irrigated Mixed hay- alfalfa -grass mixes range from 2000 to 8000 <br />pounds of annual production. <br />Non -irrigated alfalfa grass mixes range from 1500 to 4000 pounds of <br />annual production. <br />Non -irrigated grass (intermediate wheatgrass) this range goes from <br />800 to 1800 pounds of annual production. <br />Non -irrigated alfalfa grass mixes range from 1500 to 4000 pounds of <br />annual production. <br />Fig. 4.5 —1.
