| Tartalmi kivonat: | The studies and research on which the present paper is based aimed at assessing the soil in the grapevine plantation of the Didactic Station in Timisoara as a nutrition environment for grapevine whose goal was to supply a fertilisation variant that ensures nutrient bio-availability and optimal nutrition to the plants. Taking into account the biology of the grapevine, we can say that soil is, on grapevine plantations, of great interest for nutrition due to the large edaphic volume distributed over two soil horizons: 0-20 cm and 20-40 cm. This is why we have characterised the soil over the two levels of interest in water and nutrient supply for grapevine plants. The soil on the grapevine plantation can be characterised as a heterogeneous nutrition environment if we take into account the two levels of supply of nutrients. Nutrients have different physical-chemical features due to the factors and conditions that impact them. The horizon 0-20 cm has a higher content in organic matter; it is worked, aerated, more oxygenated, and more subjected to more significant chemical and reaction changes as a result of applying organic and mineral fertilisers. From the point of view of the reaction, the studied soil can be characterised as a neuter reaction medium over the horizon 0-20 cm (pH = 6.85) and as low acidic over the horizon 20-40 cm (pH = 6.30). Humus content (H) is 1.85% over the horizon 0-20 cm and 1.70% over the horizon 20-40 cm. Total nitrogen content Nt is 1.141% and 1.30%, respectively. Mobile phosphorus supply is 28.55 ppm over the upper horizon and 23.41 ppm over the horizon 20-40 cm. Available potassium ranges between 155.05 ppm over the upper horizon 0-20 cm and 141.2 ppm over the horizon 20-40 cm. The value of the nutrition environment pH is neuter to low acidic which results in a relatively good macro-element bioavailability. As for phosphorus, there is the possibility of lower-mobility calcium phosphate development, but fertilisation makes possible a proper nutrition. Soil supply in nutrients and organic matter ensures a proper nutrition environment. |
