Integrated crop–livestock systems (ICLS) associated with crop rotation and soil conservation management cause numerous changes in nutrient fluxes and soil biochemical dynamics. In this sense, there is a gap in the impact of integrated production systems on nutrient dynamics and soil microbial activity in lowlands. In this context, this work had the objective of evaluating the nutrient availability and the activity of extracellular enzymes in a Gleyic Luvic Planosol under ICLS. The experiment has five paddy‐farming systems with a range of crop diversity (both in time and space) and grazing occurring mainly in the winter season. Soil solution samples were taken in cropping seasons (2014/2015, 2015/2016, and 2016/2017), from the first day after flooding (DAF) to approximately 70 DAF. The integration of rice with livestock increased urease activity (+84%), β‐glucosidase (+49%), and fluorescein diacetate (+105%), especially as the level of diversification and use intensification of pastures. In general, there was an increase in the availability of ammonium (+70%), phosphorus (+177%), potassium (+62%), and calcium (+20%) in the soil solution with the adoption of ICLS and soil conservation management, compared with the traditional rice system. Thus, the adoption of ICLS contributes to increase the process of biochemical functioning of the soil with consequent intensification of nutrient cycling and availability. Thus, the ICLS can sustainably increase nutrient availability in the soil and reduce the need to feed large amounts of fertilizer into irrigated rice production systems
