<br />ou:>q <br /> <br />is actually supposedly reserved for the next <br />year's crop, that is actually going to be <br />there. In fact, we have some information, <br />I just happened to remember, a few years ago <br />the three-year average down in Springfield, <br />Colorado, where, during the period from May to <br />September, something like three inches of water <br />was actually lost from the soil over and above <br />that which fell as precipitation during that <br />period. So this type of thing is of low <br />efficiency. <br /> <br />I <br /> <br />Further, we have been interested under <br />dry-land conditions with such practices as <br />microwatershed techniques. We call it that in <br />a broad term. Actually, what we are concerned <br />with is the possibility of instead of having a <br />number of acres under fallow and a number of <br />acres being planted in a particular year, we <br />might, if we can develop economically feasible <br />techniques, have a similar amount ot area not <br />cropped or in fallow, then a similar area <br />cropped, but these areas being small in extent, <br />and then not ever attempting to plant on the <br />fallow areas, to use them as a microwatershed <br />and simply divert the water from those small <br />areas over to other small cropped areas. Small <br />simply because I assume that the diversion and <br />the transport of this water would have to be <br />over small distances. <br /> <br />This type of thing we are concerned with. <br />The efficiency is going to go up tremendously <br />with this type of thing and has in our experi- <br />ments because an additional 15 inches of water <br />on the land in a l2-month period, in addition <br />to the normal 15 inches, gives us 30 inches of <br />water. We can certainly do a lot more with <br />that 30 inches in terms of production per unit, <br />per inch, than we can if we simply have that <br />15 inches spread over twice as much area. We <br />have been working therefore with such things as <br />physical and chemical treatments of the soil <br />surface in order to cause water not to enter <br />the soil but to run off from our contribution" <br />areas and then enter rapidly in our cropped <br />areas. <br /> <br />I <br />
