The transition from systems characterized by the rotation between agriculture and pastoral livestock farming to others that are more intensive in the use of inputs and land has caused several negative environmental impacts worldwide, and the Argentinean Pampas Region was not spared. Given that the inclusion of winter crops in rotations is essential to reduce negative impacts, the aim of this work is to apply remote sensing techniques to determine the integrated agricultural-livestock area in a productive cycle (1 year) in agro-productive areas located in the peri-mountainous sectors of the counties of Azul and Tandil. Methodologically, the starting point was the spatial delimitation of the study area using a Geographic Information System. Then, the digital processing of 2 satellite images corresponding to the months of October 2021 and May 2022 was carried out, allowing the determination of the integrated areas using map overlay techniques. While integrated areas covered 13.54% of the total, agricultural areas were the most representative use, accounting for 47.80% of the surface analyzed. Although this is a first approximation, the study lays the foundations for future research that will contribute to the sustainability of the region's agro-productive systems.

Sward structure and post-grazing heights (SH) significantly influence plant growth and animal intake, crucial for dairy grazing systems. However, these interactions are dynamic and vary with season, resource heterogeneity, and defoliation patterns. Seasonal effects of control (TC), medium (TM), and lax (TL) post-grazing SH of grazed Lolium arundinaceum-based pasture on forage production and utilization, herbage mass, green cover, and chemical composition were tested during autumn-winter and spring seasons and among tall (TP), medium (MP), and short (SP) patches in spring. Thirty-six lactating Holstein cows were randomized evenly to TC, TM, and TL grazing treatments to achieve 6, 9, and 12 cm of post-grazing SH during autumn-winter, and 9, 12, and 15 cm in spring. Forage production was higher on TL than TM and TC, yet utilization was similar across all treatments. The TP relative to MP on SP increased for TL compared to TC and TM. The TP-TC presented higher leaf-density and leaf-proportion, than TP-TL, without modifying leaf canopy distribution of superior-medium horizons among treatments. Grazing management modulated forage production and structural heterogeneity across SH treatments. Critically, monitoring patch-level dynamics—rather than mean height—is essential for optimizing production and harvest efficiency in temperate systems by improving grazing horizon accessibility.
