The diagnosis and recommendation integrated system (DRIS) was developed by Beaufils (1957, 1971, 1973) as an objective means of coping with the difficulties inherent in diagnostic procedures.

Sources, Amounts, and Forms of Alkali Elements in Soils,he half-life of this isotope of Fr is only 21 min, however, even the existence of Fr in soils has been difficult to establish. Some work on the geochemistry of Fr and the contribution of Fr to the radioactivity of soils has been reported (Maddock, 1963), but this element is not considered further here.

Although a quasi-state equilibrium in K exchange can be achieved in the laboratory, these conditions are seldom if ever attained under field conditions.

However, in many developing countries almost half the people are under 15 years of age, poised to enter their productive and reproductive years. The challenges to produce enough food for this growing population will remain great. Even more challenging is growing the food
