Show TIMOTHY ON IRRIGATED LAND Flooding From Field Ditches Is Most Popular Method Soil Should Determine Distances. Probably more irrigated luid on which timothy is grown is irrigated by flooding from field ditches than in any other way. When this system Is used, ditches are plowed from the lateral ditch to different parts of the field and are distributed in such a way as to carry the water along the slopes or ridges, from which it can be diverted to flow over the surface of the soil. These ditches are made with a plow, preferably one having a double moldboard. The distance apart that the ditches should be and their location are determined deter-mined chiefly by the character of the Boil, the slope of the land ,and the volume of water available for irrigating. irri-gating. According to Prof. Samuel Fortier the average distance apart that the lateral ditches are placed is about 80 feet; the distance may vary, however, from 30 to 40 feet to 2110 feet or more. VTien the water is to be turned on th-a land, it is diverted from the main d'tch into the field ditches: Dams are placed at the proper places in these ditches, so as to cause the water to flow over the surface of the land ad-Jr'ning ad-Jr'ning the ditch. When the soil to be Irrigated from this point has become sufficiently moist, the dam is removed and another is placed farther down the ditch, from which more land is watered. This method of procedure is followed until the whole field has I been irrigated. |
