Abstract
Polish agriculture, as distinct from the European one, has struggled with the problem of excessive soil acidification for many years. Thus, in times of strong competition on the agricultural market it is important to look for efficient and also cheap methods to ensure an improvement of acidity of Polish soils. The aim of the present study was to determine if the negative effects of acidification were of a durable nature and if these effects could be removed by single applications of relatively small doses of lime. This aim was achieved based on soil material from a long-term fertilizing experiment situated in £yczyn, central Poland. This experiment comprises of fertilizing treatments constituting all combinations of basic nutrients used in fertilization N, P, K, Ca in only mineral fertilization system and in the system of mineral fertilization with farmyard manure (FYM). The experiment was carried out on the grey-brown podzolic soil. The chosen experimental objects were not limed since 1960 and the yields grown on these treatments were very low. As a result of a single liming, significant increase of potato, spring barley and rye yield was observed. The soil pH increase resulted in statistically proven growth of available and active phospohrus, which is evidence of the soil reserve phosphorus activation. The study results indicate that it is very easy to disturb the ion balance of sandy soil and thus reduce its productivity in unstable nutrient management conditions. On the other hand, it is possible to restore the productive value of soil with little financial input.
