Influence of absolute soil humidity on the porosity of soil packing

open access: yesTraktory i sel hozmashiny, 2012
The influence of absolute soil humidity on the porosity of soil packing is shown. It is noted that soil porosity will be reduced at the expense of decreasing of air pores and increasing of solid particles volume as a result of soil compression with mover, strake, block etc. at constant humidity. The analysis of obtained models is given.
