Field investigations were carried out during 2000 on 280 soil samples taken from the tobacco producing region of Bitola. Samples were taken from a depth of 0 - 30 cm and the following param - eters were included in investigations: humus, carbonates, pH reaction, total nitrogen, available phos-phorus, available potassium and the content of physical clay (particles <0.02 mm). According to the content of humus, the soils in this region are suitable for growing of oriental aromatic tobaccos. The Total N supply in the soils completely satisfies the requirements for tobacco production. The supply of available phosphorus is mainly inadequate and fertilization of these soils with higher rates of phosphorus fertilizer is an indispensable measure.
With respect to the available potassium, these soils are well supplied with this element and suitable for growing of a high quality aromatic tobacco. Based on our investigations of the soils in this region, we can recommend application of mineral fertilizer NPK 8: 22 : 20 in a quantity of 300- 400 kg/ha, depending on the fertility of soil. On the areas which have a poor supply of phosphorus and good supply of potassium, a complex fertilizer NP (16 - 32) in a quantity of 150 - 250 kg/ha is recommended.
