Opis:: Loess constitutes a building site for over 6% area of Poland. Almost the entire area of its occurrence undergoes construction development. In the event of their sudden irrigation, a rapid reduction in the volume of the soil occurs. This process is known as hydrocompression. It is particularly dangerous in urban areas, where there is bulk land next to loess. The increase in humidity of these soils results in large changes in strength and deformation characteristics. At present, most construction damages caused by the phenomenon of hydrocompression are not the result of typical long-term moistening of soils by rainwater, but especially by errors in development: leaky sewerage, rainwater discharge to the ground or waterworks failure. The project encompassed the test of an original subsidence monitoring system in a specially designed physical model fit for this purpose. The aforementioned system was created on the basis of the ARDUINO platform that enabled monitoring of subsidence with an accuracy of 0.2 mm.

Tytuł:: Plough sole as the result of the agricultural land use

Opis:: The purpose of this paper was the estimate of the substratum compaction in various soil types and under various conditions of use. The compaction characteristics were performed on the basis of bulk density of soil. It was performed on various types of soil, built of various materials, occurring in the vicinity of Płock. The soils are farming land. The greatest substratum compaction was observed in arable lands, built of light loam, silt and loamy sand. The difference in bulk density between the layer at the depth of 25 - 35 cm and the adjacent horizons reaches 0.3 Mg per cubic metre. In soils used for green crops the substratum layer does not show a large difference between the adjacent layers, but the values of bulk density are equal to about 1.6 - 1.8 Mg per cubic metre already near the surface. Higher values of bulk density at the depth of 25 - 35 cm were observed in 68% of soils under investigation.
