Megjegyzések:	Over the last few decades, the rate of soil acidification has been increased by intensive land use in most agricultural production systems. The objective of this study was to identify in which extent the acidification of a calcareous chernozem soil could be affected by fertilisation, irrigation, and tillage. This study was conducted in 2007 at the Látókép Experiment Site of the Centre for Agricultural and Applied Economic Sciences, Debrecen University located in the north-eastern part of the Great Hungarian Plain. The examinations were carried out under irrigated and non-irrigated conditions, in the 0, 120 and 240 kg N ha-1 plots, respectively. The investigated tillage treatments were winter ploughing (WP) to a depth of 27 cm, spring ploughing (SP) to a depth of 22 cm and disk tillage (DT) to a depth of 12 cm. Soil pH measurements were made using portable Sentron Argus pH Meter equipped with Sentron Hot-line LanceFET probe to a depth of 0-10 cm. Soil acidification was significantly affected by all investigated factors. Typically low soil pH was measured in the DT treatment with 240 kg N ha-1 under irrigated conditions. Based on the results of this study, the applied high dose of nitrogenous fertiliser with inappropriate tillage practice could accelerate the acidification of soils to a great extent under irrigated conditions. Land users have to support the regeneration of soil conditions by regularly applying lime to counter the acidification processes.
