An economical analysis and evaluation of the results of differeniated fertilizing and liming rates application in three experimental bases, situated on Planosols from North Bulgaria, Cambisols and Modic Cambisols have been made. It has been established that the yield increase from one soil unit is insufficient to compensate the input (expenses) for the most of the technological variants. The variants with low fertilizing and liming rates have terned out to be economically effective (Ist level), as well as those with higher nitric rate (IIIrd level), combined with the lowest liming level. In experimental fields Korita and Bilo the variant with macro-fertilizing and Mo applying of IInd level is also effective only without liming.
