|Abstract: ||Extensive livestock production systems based on improved pastures under Montado of
Holm oaks represent an approach in line with the challenges of sustainability and biodiversity. The
increasing incorporation of technologies in the monitoring of this ecosystem allows for a better
knowledge of the spatial and temporal variability and, consequently, a more economically profitable
management. In this study, between July 2020 and June 2021, soil and pastures were monitored in a
20 ha Montado area located in Alentejo (Southern Portugal) and used for extensive grazing of cattle.
The survey of soil apparent electrical conductivity (ECa), the application of algorithms for definition
of homogeneous management zones (HMZ), the use of indices obtained from satellite imagery time
series to characterize the evolution of pasture quality and the soil and pasture sampling, including
the identification of bio-indicator botanical species, were the basis of this exploratory study, allowing
a holistic approach to this complex soil-pasture-trees and animals ecosystem. In the near future, this
knowledge could represent an important milestone in providing decision-making support systems
to farm managers in terms of smart sampling, differential application of fertilizers, amendments or
seeds, choosing the best spacing and density of trees in this ecosystem, promoting dynamic grazing,
or identifying the animal feed supplementation needs in the critical periods of the year.|
