Abstract. The paper presents results of landscape planning and investigation on Fluvisols. The object is "Kubratovo 1" sand and gravel deposit, Bulgaria. Soil samples were taken from twenty- one soil profiles at a depth of 0-20 cm, 20-40 cm, 40-60 cm, 60-80 cm, and 80-100 cm. The changes in physicochemical properties were investigated at different soil depths and the relationships between different soil characteristics were tested. There are statistically significant positive or negative regressions. There are regression relationships between the soil texture fractions and bulk density, total porosity, soil organic matter, total Kjeldahl nitrogen, available phosphorus and available potassium.  of analcite, tripoli and silicon dioxide effect on soil moisture level was discussed.
 
Key words:  Landscape planning, soil, Fluvisols, physical properties, chemical properties, urban green system.
