The Effect of Manure, Commercial Fertilizers, and Lime on Some of the Physical Properties of Marshall Clay Loam, Heavy Subsoil Phase.

The following study was conducted for the purpose of determining the effects of treatments with manure, lime and manure, and commercial fertilizers upon the physical properties of the soil.It was the object of this investigation to measure any differences which had come about as a result of the treatments.As a means of measuring these possible influences, the Atterberg constants, the moisture constants, and the volume weights were determined.The Atterberg constants which were used were the upper plastic limit, the lower plastic limit, the plasticity number, and the scouring point. The moisture constants employed in this study were the moisture equivalent, the hygroscopic coefficient, the available water capacity, and the maximum water capacity.The greatest attention was focused upon the effects of manurial applications upon the soil, because the chief fertilizer used in Nebraska at the present time is manure.

Letter dated 8 November 1965 from B. R. ("Rod") Bertramson at the Washington State University Department of Agronomy in Pullman, Washington, to Lorenzo A. Richards at the U.S. Salinity Laboratory in Riverside, California, regarding the recent meeting of the American Society of AgronomyWASHINGTON STATE UNIVERSITY PULLMAN, WASHINGTON 99163 DEPARTMENT OF AGRONOMY November 8, 1965 Dr. L. A. Richards, Past President American Society of Agronomy U. S. Salinity Laboratory P.O. Box 672 Riverside, California Dear Ren: Re: ASA Meeting, Columbus, Ohio, November 1-4, 1965. This meeting culminated a year of dedicated effort and continued achievements on your part on behalf of the Society. Each adds his bit of color and person­ality to the kaleidoscope of passing administrations. Your geniality, keeping the tenor pleasant and light hearted -- even though handling serious matters was truly in the Richards tradition. I thought on numerous occasions at this year's meetings, how typical of the soil physicist, Richards, everything progressed. Things seemed to go as though tempered and contained in the Richard's constant temperature room. And each problem was notably described and skillfully solved - just like your Soil Physics Research. You have done a grand job. The Society has moved forward under your able leadership and administration, and we all grow a bit prouder of our Society! Likewise we are all grateful for your dedicated services that have served the Society and us so well. Sincerely^--^ W< R. Bertramson, Chairman BRB:l
