PHYSIOLOGICAL ASPECTS OF AVAILABILITY OF NUTRIENTS FOR PLANT GROWTH

Abstract
A brief review, principally concerned with the work of the Laboratory of Plant Nutrition at the Univ. of California. The following topics were considered: nature of physiol. processes involved in ion absorption, micronutrient elements, interdependence of factors in the study of availability, the appraisal of soil deficiencies, chem. and biol. tests of availability, and practical methods of ascertaining nutrient deficiencies.
