Changes in soil properties also on microflora attribution are due to the use of different soil management practices. The objective of this study was to determine the effects of management on soil fungi amount in contrasting cropping systems in the Endocalcari-Endohypogleyic Cambisols in Lithuania. The cropping systems differed in management intensity with respect to fertilizer quantity. Spring barley (Hordeum vulgare L.), clover (Trifolium repens L.), winter wheat (Triticum aestivum L.) and spring rape (Brassica napus L.) were grown in rotation; also long time used pasture was involved. Collection of soil samples was done in the autumn of the years 2002, 2003 and 2004 and was quantified viable fungi as CFU's. The data indicate that number of fungi depended on the cropping systems. Stimulation effect by fertilizers was obvious in intensive and bioorganic systems. Also different plants had impact on fungi amount; a general tendency was observed that barley and wheat not favoured the quantity of fungi in soil, while the pasture, rape and clover had an augment effect for quantity of fungi over experiment. Also was determined a particular year impact on fungi amount, in years with prevalent wet conditions was detected a increasing by half.
