The experiments were carried out to evaluate dynamic trend of soil microbes in various seasons on
existing cropping patterns on sloppy arable lands of Kahuta area. For this purpose, a series of experiments were
initiated to monitor the soil biological status under wheatmaize and wheat-mungbean cropping patterns. From both
patterns, soil samples were taken in summer, winter, spring and autumn seasons. The results differed significantly for
soil microbial biomass carbon (SMBC), soil microbial biomass nitrogen (SMBN), soil microbial biomass
phosphorus (SMBP) in all seasons under wheat-maize and wheat-mungbean cropping patterns. Similarly, soil
enzymes, particularly soil dehydrogenase (SDH) and soil alkaline phosphatase (SAP) activated heterogeneously in
these sites throughout the year and had a significant
