Overview

Excerpt from Eighth Technical Alfalfa Conference Proceedings: Held at Colorado Springs, Colorado, February 6, 1963 For brevity, these results are reported on a subject-matter basis with out regard for location of work, in general. Agronomic. California studies on the effects of plant nutrition and harvest procedures are reported in their Experiment Station Bulletin 784 entitled Controlling alfalfa quality. The studies were extensive. This bulletin was mentioned in Behy Review and other media. It is available upon request from the California station. Alfalfa fertilizer requirements for the Rio Grande Valley of Texas revealed exceptionally favorable response to phosphate. The Bray method for determining phosphate requirement could be modified for use with alkaline soils. Studies of the root system of sub-irrigated alfalfa revealed two impor tant regions for water and nutrient sorption-the moisture fringe above the water table and the surface soil. In land continuously cropped to alfalfa, phosphate content was reduced to the ll-foot level. Available nutrients in the soil substrata must be evaluated before reasonable fertilizer recommendations can be made. This was some of the initial work on the use of radioactive chemicals.
