Don't furrow an area where you plan to hay. Don't cross where you travel 

 with the family car. Don't look back if you have a weak heart and then 

 when you look at this one year later, don't put the hired man on the mach- 

 ine and go to town with the truck to put on more livestock. 



We can take a look in a more dense clay soil and see what is done to 

 the big sagebrush and fringed sage. I would point out here that fringed 

 sage in drier years will come in almost to the point that it will frighten 

 you, but as soon as the western wheatgrass which is the predominent grass 

 in our area, starts to respond, it will stop the fringed sage so it is no 

 longer a problem. You can see on the edge of the furrow that the western 

 wheatgrass rhizomes have already started growing and in the bottom you will 

 notice some of the interseeding we have done. We have tried various grasses, 

 several varieties of alfalfa and sanfoin. On native rangeland we feel that 

 the only seed that you might want to put on that you will get your money 

 back from is about two pounds of alfalfa. 



Here we are seeing on our left, four years of growth on a treated area. 



You will note in the foreground several plants of winterfat which is a very 

 desirable plant and grows well in our area. For some reason this seems to 

 cultivate winterfat but even more so nuttalls saltbush. To the right you 

 see an area we just went through with the conto\ar f\irrower for a demon- 

 stration at a Society for Range Management Section Field Tour. We have 

 been very fortunate in the work that we have done there in that the Agri- 

 culture Research Service has been down and put in fertilizer test plots, 

 some included contour furrows. They made an extensive evaluation of that 

 area with mixed results. We have these available, but due to lack of time, 

 I will not discuss the plots in detail. I will show this slide and want 

 to give Dr. J. Ross Wight credit for this slide. He is from the Soil and 

 Water Research Center in Sidney, Montana, who is very instrumental in this 

 evaluation. You will notice that they started evaluation in 197'' • You 

 have the graph that shows the untreated range. We have 300 pounds of avail- 

 able nitrogen and at that time Dr. Wight said the cost was about $55 per 

 acre. You see the production from the furrows broken down with alfalfa 

 seperately showing the advantage of contour furrowing with about two pounds 

 of alfalfa seed per acre which would run about $7.50 per acre. They expect 

 that another 100 pounds of fertilizer would have to be applied every three
