Show WASTEFUL IN USE OF WATER eptd or Ovtrtaturaud Lands Csused by Wait From Irrigation or Leakage Prom Canala. The cause of speed or ovcrssturat-sd ovcrssturat-sd bind Is the waste from Irrigation and leakage from emmis and laterals The skillful irrigator may Jun!t that If no more water Is applied thnu lit needed for growing ami mutuiir.g crops, and that If the canals are no constructed tlint no substantial amount of water eseipes Into the tnrth, no land will become too wet for farming purposes, says the Denver Den-ver Field and Farm. It. Is true tlittt In many Instance Irrigators have beti unduly prodigal In the use of water, particularly when the land Is first subdued Mid watered. The art of economical Irrigation Is usually learned only when scarcity of water compels Its less lavish use. In any event, under present methods meth-ods some wuto of water will occur under the best of management, making mak-ing draining In many places essential to profitable farming. Water which produces permanent saturation rises from the bottom of the saturated soli toward the surface. Waste from Irrigation Irri-gation first passes downward until a hard stratum of earth Is reached. This may be only a few feet. In which case the additions which accrue from the Irrigation of a few years will bring the permanent ground water level to within with-in two or three feet of the surface, at which time Injury to farm crops will ensue. It Is not the downward move ment of water alone which occasions hoKgy or wet areas, but the lateral movement of ground water down a Blope until a flat tract or surface depression de-pression checks the flow and causes an accumulation of water, which Is made known by Its appearance, but not until the lower parts of the soil have been filled. Much depresHlons or level areas receive re-ceive the accumulated waste water proceeding from adjoining lands, which occupy a higher level. It will be seen that the saturated condition of the land which shows Injury Is not due to the water which Is applied directly di-rectly to Irrigate It, but to the surplus which percolates from the higher lands, sometimes through considerable distances, until It reaches the lower flat or depression and Colorado now has a law providing for the organization organiza-tion of drainage districts In which the expense of putting In the drains Is borne by the entire acreage. Drain-Age Drain-Age has been carried on In the west to such an extent that certain methods meth-ods are now practiced with reasonable assurance of success. The development develop-ment along the last five years is most encouraging to holders of seeped land. |
