Table 3, Results of microbiological soil analyses after applying soilconditionersCO 2 (R) - so called reactive production of CO 2 in the soil after 1-day earth pre-incubation(mg CO 2 . kg -1 .1d -1 )CO 2 (B) – basal production of CO 2 in the soil after 5 days of earth pre-incubation(mg CO 2 kg -1 . 1d -1 )CO 2 (G) – production of CO 2 in soil samples with added glucose solution (mg CO 2 . kg -1 . 1d -1 )G: B – ratio of soil respiration with added solution of glucose and basal production CO 2 (B)CO 2 (NG) – production of CO 2 in soil samples with added solution of mineral N and glucose(mg CO 2 . kg - .1d -1 )NG: B - ratio of soil respiration with added solution of mineral N and glucose and basalproduction CO 2 (B)NH 4 -N, NO 3 -N - instantaneous content in mg. kg -1TMN – total mineralization of nitrogen in soil (mg NH 4 -N. kg -1 . 14 d -1 )NIT – nitrification in soil (mg NO 3 -N. kg -1 . 14 d -1 )EX_C – content of extra cellular C in soil (mg C. g -1 )MB_C – content of carbon in total microbial biomass in soil (mg C. g -1 )Determination of total microbial biomass (MB_C) in the soilwas a part of microbiological analyses. The determination comprisedbacteria, actinomycetes, micromycetes and a small proportion ofalgae, protozoa and nematodes with the volume smaller than 5µm 3 .From practical viewpoint analyses are significant, first of all for thatfact that in the biomass of microorganisms 0.5-15% of soil nitrogenis fixed, whereas nitrogen circulation from dead cells is about 5~ 268 ~
