The paper presents results of landscape planning and investigation on Fluvisols. The object is “Koriata” sand and gravel quarry, Bulgaria. Soil samples were taken from seventeen soil profiles at a depth of 0-20 cm, 20-40 cm, 40-60 cm, 60-80 cm, and 80-100 cm. There were significant correlations between the physical and chemical soil properties in 40 out of 48 cases. Statistically significant high correlation coefficients (> ±0.6) have been calculated: for example, there is a negative correlation between bulk density on the one hand and soil organic matter (SOM) and nutrients on the other; there is a high positive correlation between total porosity and SOM and nutrients. The correlations between the clay fraction and SOM, total Kjeldahl nitrogen (TKN) and K2O are also high. Formulating a landscape plan for the territory of “Koriata” sand and gravel quarry will improve the quality of life of residents, will result in at least a sevenfold increase in plant diversity and will meet the demand for themed waterparks within the city limits of Sofia.
