Book Description
Excerpt from The Principles of Irrigation Practice Irrigation and dry-farming are rapidly conquering drought. By these twin arts, bountiful and regular harvests may be gathered in the humid regions during the periodic dry seasons; and in the arid regions, the great deserts may be converted into most fruitful fields. Irrigation has a splendid record of success from the begin ning of history; dry-farming has only in recent days extended its conquests into the more arid regions; both have become more powerful in conquering drought as modern science has been applied to them.

Book Description
Excerpt from Irrigation and Drainage: Principles and Practice of Their Cultural Phases Great pains has been taken to personally inspect the irrigation practices of both humid and arid climates in this country and in Europe, to gain a broader view of essential details, and to secure suitable illustrations, which are presented largely as photo-engravings, in the hope of getting closer to the spirit of the subject.

Book Description
Excerpt from Irrigation of Crops in the Southeastern United States: Principles and Practice For typical crop, soil, and climate situations, procedures are outlined for selecting irrigation equipment and for operating the equipment to provide the dependable soil-water control necessary for meeting a crop's water needs. The recommended procedures emphasize crop and soil characteristics and the maintenance of a critical soil volume at less than a specified soil-water suction. Equal emphasis is placed upon excessive water application and the leaching of nitrogen or other mobile nutrients out of the root zone. The option of supplying certain chemicals, particularly readily leached nutrients, through the irrigation system is discussed.

Book Description
Excerpt from Irrigation: Its Principles and Practice as a Branch of Engineering Irrigation is a subject which covers much ground, and cannot be confined within the narrow boundaries of a single volume. But the principles on which Irrigation Engineering is based can be collected in small compass, and be illustrated by examples of actual practice to the extent that space allows. What, therefore, this work attempts to do is to set forth the guiding principles that should govern the practice of irrigation, and to furnish illustrations of their application in existing canal systems. The majority of the illustrations have been selected from the wealth of material that the irrigation experience of India and Egypt supplies, for the following reasons. In the first place, I have been personally connected with irrigation in both countries, and can therefore handle the facts, relating to them, as one having authority on the subject, and not as the scribes, Whose methods I might be imitating were I to draw my illustrations from the records of other countries. In the second place, it is India that furnishes examples of irrigation on the largest scale, and that has been the school in which all British irrigation engineers, previously to England's occupa tion of Egypt, have undergone their training. Moreover, the excellent standard work on the subject, The Irrigation Works of India, by R. B. Buckley, provides in a convenient form more than enough material for copious illustrations, and I have made much use of it, with Mr. Buckley's kind permission. But it will be found that Egypt has been the favourite source of my borrowing. There are two good (so it appears to me) reasons for this. The first is that I am intimately acquainted with Egypt as an irrigating country. The second is that Egypt is par excellence the country of irrigation, as it is wholly depen dent for its existence on its mother, the Nile, from which it has never been weaned.

Book Description
Excerpt from The Principles of Irrigation Practice Irrigation and dry-farming are rapidly conquering drought. By these twin arts, bountiful and regular harvests may be gathered in the humid regions during the periodic dry seasons; and in the arid regions, the great "deserts" may be converted into most fruitful fields. Irrigation has a splendid record of success from the beginning of history; dry-farming has only in recent days extended its conquests into the more arid regions; both have become more powerful in conquering drought as modern science has been applied to them. Successful irrigation-farming is the joint product of the engineer and the farmer. To the engineer is given the heavy and responsible task of constructing properly a permanent system of dams and canals from which water may be drawn; to the farmer belongs the apparently humble but unending and difficult task of using the water in the best manner for crop-production. Both workers are essential for success; but, the work of the farmer determines the permanence and extent of agriculture under irrigation. Much has been written about irrigation for the engineer, but little for the farmer. The few who have written about farming under irrigation have, most frequently, prepared crop or soil manuals, in which the use of water has formed a minor part.
