Abstract. Influence of compost from municipal wastes (MSWC), used as a fertilizer, on some physicochemical and physical properties of the soil such as: pHkci, total porosity, bulk density, specific density, water retention at pF 2.54 of field water capacity as well as pF range of 1.0 - 2.9, is presented in the paper. The paper is part of a general project analysing the possibility of using compost from municipal wastes in horticulture.
