THE DISTRIBUTION OF THE ROOTS OF SUGAR CANE IN THE SOIL IN THE HAWAIIAN ISLANDS

outlined in this paper were developed. These methods with slight modifications are feasible for use with a number of crop plants, so that they may be of interest to other investigators in the plant sciences. An examination of the stimulating studies by Weaver (3), and his associates, in which the literature of root studies has been extensively reviewed, indicates that the methods employed in the present studies have not been previously in use, to any general extent at least. In growing sugar cane or almost any crop, a large proportion of the cost of producing the crop is chargeable to the operations of tillage in preparation for root growth. It is obvious that this investment in tillage can be more intelligently made if it is known where the roots of the crop will extend or where they may be made to extend. Moreover a knowledge of the distribution of the roots enables one to prevent their injury by cutting or mutilation during the operations of cultivation. Determinations of soil moisture may be confined to the levels of the soil where the roots exist, if it can be determined where the large proportion of the roots become distributed. Irrigation applications can be more economically applied, and water conserved if it is known where the roots exist. The greatest efficiency in the use of fertilizers depends on placing them where they will be quickly available to the greatest number of roots. This is a concise statement of some of the more ready applications of knowledge of root distribution to economical and efficient crop production. Weaver (2) has discussed in greater detail many applications of this knowledge to the growth of plants.
