In this thesis, we researched the spatial variability of selected chemical properties of soil in the area of selected olive tree. We specified the content and variability of available phosphorus, potassium, organic matter and soil pH. Soil samples were taken in the olive grove in Škofije at different distances from the trunk (from 1 to 4 m) and at four different depths (0⠒10 cm, 10⠒20 cm, 20⠒30 cm, 30⠒40 cm). The results showed that the most variable were the contents of phosphorus and potassium available to plants. Organic matter content and pH changed the least. The phosphorus content ranged from 4.45 to 8.67 mg/100 g soil. The potassium content ranged between 17.50 and 24.90 mg/100 g soil. We found out that the levels of pottasium and phosphorus decrease with depth with both properties. The variability of phosphorus was greater than of potassium. The organic matter content was between 2.1 and 2.5 %. Its content did not vary significantly with depth. The soil reaction ranged from 7.14 to 7.27 and did not decrease with depth.
