The Protected Landscape Area Zahorie is spread on an area of 27,522 ha on the Borska nizina lowland. It consists of the localities Horny Les and Dolny Les on the alluvium of the Morava river left bank and Kobyliarka elevation between the villages Borsky Svaty Jur and Laksarska Nova Ves Sandy (arenic) soils are spread on the area of 9052 ha (33% of the whole area). They are developed on eolian and alluvial sediments. They ere without carbonates, what is the reason of their acidity. Soil acidity is increased from Mollic Fluvisols, Eutric Fluvisols, Dystric Regosols to Haplic Podzols in the catena of natural arenic soils without significant anthropic influences as cultivation, fertilization and liming are a result of pedogenetical processes. The lowest content of humus in very shallow humic horizon (0.2 m) was determined in Dystric Regosols. It corresponds to the composition of vegetation type Thymo angustifolii-Corynephoretum canescentis Kripel 1954 with low biomass production of the herb layer, which was determined in thc area "Vo Vrskoch" near the village Laksarska Nova Ves. Eutric Fluvisols in the locality "Cierny les" in the district of the village Gajary has a deeper humic horizon (0.5 m), with higher content of humus. It was developed in the process of humification of plant residues of vegetation. The highest biomass production of the plant community type Pleurozio schreberi-Pinetum, Somsakova 1988, with higher biomass production of the herb layer. Higher biomass production of phytococnoses Fraxino-pannonicae-Ulmetum Soo in Aszod 1936 corr. S o o in deep humus horizon creation (0.9 m) of soil type Mollic Fluvisols. This soil has the highest content of humic substances of high quality from arenic soils on thc locality "Siroke" near by the village Vysoka pri Morave
