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.
