Show TIME OF IRHIGATION Character of Soil and Subsoil Has Much Influence.

If aucti i a noil Is underlaid with gravel tho water will drain out and nioro frequent fre-quent Irrigation will be necessary. Th same principle holds with lighter polls. The lighter the nulls and the i more open the nuhiolis the more fre-! fre-! quently It will be necessary to Irii-j Irii-j pate. The lighter rolls have less wa-) wa-) ter capacity, ao that the Irrigations should be ll;ht and frequent. The Ideal condition seems to be to have Biifliclent moisture In the soil at the time of needinK to germinate the ! Feed and keep the plants growing tin- til they are large enough to ahade the ground when the crop Is Irrigated, It la Irrigated again when the grain la In the boot that la, when the heads are Just beginning to show and soine-i soine-i times again when tho heads are lining. lin-ing. In localities having a small water precipitation or where tho evaporation evapora-tion Is excessive during tho winter months, as Is tho case along part of the l'acillc roast, In New Mexico, Arizona, Ari-zona, nnd a few other localities, the utility of Irrigation during the non-growing non-growing aeaaon has been demonstrated. demonstrat-ed. Where the water supply Is deficient, defici-ent, Irrigation at n time when the water wa-ter can be obtained, either in the winter win-ter or the spring before planting. Is of service to store moisture In (he soil for the plant's use later In the season. sea-son. Winter rrlgatlon Is not well understood un-derstood or Its benefits realized as would bo the case were the pactice more extensive. Irrigation prior to planting la of great service In localities locali-ties with a limited water aupply where such supply Is required by other oth-er mid more profitable crops later In the aeason. In winter Irrigation the land la Irrigated Irri-gated once or twice before heavy freezing weather, the first irrigation two weeks to a month prior to the last one, which should occur Just be-for be-for heavy frost. The better method of winter Irrigating la by the furrow method, unless the land can be harrowed har-rowed after the hut Irrigation, as a mulched surface during the winter Is desired, that the winter precipitation may enter the aoll readily. Sufficient water should be applied to saturate the soil to a depth of four to six feet, provided the Foil Is rather deep and riot underlaid near tho surface with porous material such as sand and i gravel. Some difficulty Is experienced upon the heavy landa In Irrigating In the spring prior to planting, as the soil dries out very slowly and the grain cannot be planted until late. ' Hetter results are obtained In such ' cases by watering Just after the crop has been planted. The furrow meth- " od Is to be preferred upon medium to 1 heavy soils If Irrigation la required x at any time before the plants have at- 1 lalned sufficient growth to shade the f sromiiJ. In case water Is applied In s I he tpring before planting, the land K diould be plowed, harrowed, furrowed " Hid Irrigated.
