    Agriculture and livestock production systems are being degraded by poor management, including inappropriate fertiliser and pesticide use, intensified monoculture, and pasture degradation driven by inadequate grazing management. Improved land‑use practices such as integrated production systems therefore offer more sustainable alternatives. This study aimed to evaluate soil chemical and microbiological attributes across different production systems. Areas under integrated crop–livestock–forestry (agrosilvipastoral), integrated crop–livestock (agropastoral), conventional agriculture, and native forest (used as a reference condition) were studied. Microbiological assessments included microbial biomass carbon, basal respiration, metabolic quotient, and microbial quotient, together with functional groups of microorganisms and the percentage of mycorrhizal colonisation. Agronomic assessments recorded number of inflorescences and plant dry mass. Results were subjected to analysis of variance and means compared by Tukey’s test (p < 0.05). Across almost all measured parameters, integrated‑system sites supported larger microbial communities, higher soil organic matter content, lower environmental stress, more efficient nutrient supply, and greater plant dry mass than the conventional system. Within the integrated crop–livestock–forestry system, competition for water between trees and soybean in the tree rows impaired both crop development and the soil microbial community. By contrast, the inter‑row areas of the crop–livestock–forestry system and the integrated crop–livestock system presented more favourable environmental and soil conditions.
