The studies and research on which the present paper relies aimed at assessing the soil in the fruit-tree plantation of the Didactic Station of the Banat University of Agricultural Science and Veterinary Medicine in Timisoara (Romania) as nutrition medium for apple-trees to allow fertilisation schemes that ensure the bioavailability of nutrients and of optimal nutrition. On fruit-tree plantations, soil is of interest in plant nutrition due to its larger edaphic volume over a 0-40 cm depth. Therefore, we carried out the soil analysis and characterisation over the edaphic volume, i.e. over the two levels of interest from the point of view of water and nutrient supply for apple-trees. The soil on the fruit-tree plantation is characterised as a heterogeneous nutrition environment if we take into account the features of the two horizons of nutrient and water supply. The different physicochemical features are due to the acting factors and conditions. Over the horizon 0-20 cm, there is a higher amount of organic matter, higher aeration, and more intense oxidation phenomena; the horizon is subjected to some physicochemical and biological changes. The soil on the fruittree plantation is characterized by a neuter reaction in the horizon 0-20 cm (pH = 6.90) and by low acid level over the horizon 20-40 cm (pH = 6.39). Humus content (H) is about 1.95% over the horizon 0-20 cm and 1.73% over the horizon 20-40 cm. Total nitrogen content Nt is 1.16 % and 1.13%, respectively. Mobile phosphorus supply reaches 32.55 ppm in the upper horizon of the soil and 29.4 ppm in the horizon 20-40 cm. Assailable potassium reaches between 172.0 ppm in the upper horizon 0-20 cm and 161.5 ppm in the horizon 20-40 cm. Soil reaction is neuter to low acid, which makes macro-element bio-availability relatively good. There are good conditions for the development of some low-solubility compounds (calcium phosphates), which recommends the supply of mobile phosphorus through proper fertilization.
