DEVELOPMENT of new phosphatic fertilizers whose plant food potential is not fixed by the soil before it can be absorbed by the plant was the central theme of a recent week-long conference, sponsored by the Tennessee Valley Authority at Muscle Shoals, Ala. The opportunity that exists for improvement of fertilizer efficiency through this means may be judged by the fact that less than one third the phosphate in modern fertilizers chemically available as plant food is actually assimilated by the plant in a reasonable period. The remainder becomes "fixed" in the soil. Participating in the conference were staff members of the TVA department of chemical engineering and 14 distinguished chemists and chemical engineers. These included: Roger Adams, University of Illinois; Henry E. Bent, University of Missouri; Barnett F. Dodge, Yale University; P. H. Emmett, University of Pittsburgh; Henry Eyring, University of Utah; Paul "Gross, Duke University; Sterling B. Hendricks, U. S. Department of ...
