Show RAINFALL RETAINED IN SOIL ! Possible to Store Approximately 21 Inches of Water In the Upper Ten Feet of Ground. Jly D. W. FIIEAR, Colorado Agricultural Agricul-tural Collrgn.) Actual experiments show that tnv actual Hold water capacity of arid soils varies from 14 per cent, for s very sandy loam to IS per cent, for s clay loam, with an average or about 16 per cent. The greatest water ca pacify would bo even more. At tbli rate every 12 Inches In depth of sol. can hold from 2 23 to 2.65 Inches ol water, or an avernge or 2 45 Inches At this rate It Is ponBllile to More ap proximately .26 Inches or water In tht upper 10 reel or soli. This Is from one and one half to two times the an nual rainfall over the better dry farming sections. Therefore, It should be and Is possible to storo one or twe years' rainfall In the soil, by using proper tllluge methods. |
