    The study was conducted in a static experiment established in 1993 in the Agricultural Experimental Station in Lipnik (near Stargard Szczeciński). Bi-factorial field experiment was set up in the perpendicular bands pattern of randomized sub-blocks in four replicates. Studied factor consisted of the farming systems used for winter wheat after different forecrops (faba beans, sugar beet). Analysed physical properties, shaping water management in light soil, changed depending on the previous crop grown and the amount of rainfall in the growing season. In years with larger rainfall deficits, the soil in the position after faba bean was characterized by a higher density, current humidity, and non-capillary porosity. It referred to the aeration porosity in the position after sugar beet. During years with less rainfall deficiency, the bulk density was increased after sugar beet, while non-capillary porosity decreased after faba bean. Giving up the plowing sowing for the benefit of plowless system or direct sowing modifies some physical properties of topsoils. There was an increase in bulk density and non-capillary porosity. Higher values of bulk density of the soil, listed on the objects, where the applied technologies without plowing, especially on light soils may promote the growth and development of plants commodities, including winter wheat.
