The conversion of natural grasslands to cultivated pastures has a profound effect on the soil habitat conditions,
influencing the proportion of soil specialist and generalist microbes, with consequences for the assembly of
microbial communities. This often leads to the homogenization of the microbial community and thus favoring
stochastic assembly processes. However, there is still a gap in understanding the effect of conversion from natural
grasslands to cultivated pastures on soil microbial ecological processes. Therefore, we aimed to investigate the
assembly patterns of microbial communities and evaluate the ecological models for generalists and specialist
microbes along a grassland management intensification gradient. Through 16S rRNA amplicon sequencing, we
found that the conversion of natural grasslands to cultivated pastures has increased the number of microbial
specialists, resulting in stochastic assembly processes due to the decrease in plant diversity. Moreover, the
ecological processes governing the assembly of microbial communities were affected by soil and vegetation
management. The perennial pasture was more affected by homogenizing selection, owing to the lower plant
diversity and uniform plant covering and root development. We have found that the generalists in the grasslands
are shaped by niche-based models, while the specialists in natural grasslands are more stochastic in nature. For
improved pastures, we have found that lognormal and preemption models are more predominant, suggesting that
homogenizing dispersal is more predominant than variable selection. We highlight it is essential to comprehend
these assembly models and ecological processes to ensure plant-microbe supporting and provisioning ecosystem
services for cattle, and humans while establishing management strategies and conservation policy priorities MenosThe conversion of natural grasslands to cultivated pastures has a profound effect on the soil habitat conditions,
