In 2002, as part of a campaign to improve soil fertility in the Province of Vojvodina, a total of 158 indoor soil samples were analyzed for the major soil fertility indicators (pH, humus, N, readily available P and K) and the following conclusions have been made: Soils used in plastic greenhouse production are predominantly slightly alkaline, so physiologically acidic fertilizers should be used more during fertilizer application in this type of indoor production. The humus content of most of the samples we analyzed was satisfactory. However, extremely high levels of readily available phosphorus and high levels of readily available potassium were recorded, which calls for an optimization of P and K fertilization. Primarily because of antagonism towards the uptake of ions of other biogenic elements, N-fertilizer application in plastic greenhouse production should be based on monitoring nitrate dynamics in the soil and on N-fertilizer application during the entire. This will provide vegetable crops with optimum nitrogen supply throughout the growing season and, hence, have a positive impact on yield level and quality.
