A basin is provided around the tree, with a suitable ridge to hold the water, which is then turned in until a suffi- cient amount is applied. Border Method. The border method is also similar to the check method in that the land is di- vided into long strips, and the water is turned into these from a ditch at the end or along the bor- der. It is easy to see that by arranging these long strips the work necessary in preparing ridges is reduced. Furrow Method. The furrow method of applying irri- gation water consists in turning the stream of water into furrows between the rows of intertilled crops. It is more generally employed than any other method, with the excep- tion of flooding from field laterals. The distance between furrows will depend upon the character of the soil. It is customary to provide small openings or pipes in the ridge at the side of the supply ditch by which the water may be turned into the furrows. Subirrigation. Upon first thought it would seem that subirrigation, or wa- ter applied to crops from pipes laid beneath the surface, would be an ideal system. This is not the case, as such a.
