Description: Pressures developed by alfalfahaylagein a botton-unloading concrete silo were monitored for 2 consecutive years with 15 sensors placed symmetrically around the circumference at five levels. The experimental data were used to esti mate the coefficient of friction between silage and silo wall and the ratio of horizontal to vertical pressure. These parameters appear in the formulas for the stresses that a material exerts on the walls and floor of its container. The results for both factors showed consider able scatter which is often inevitable in field tests involving biological materials. Lower and upper limits of friction coefficient and pressure ratio were recommended for the designer of farm tower silos.
