“…1) The need for a long-term platform for interdisciplinary studies in SPS In a literature review addressing the opportunities and challenges of SPS in Uruguay (Fedrigo et al, 2018), the absence of long-term platforms for interdisciplinary studies in the country was emphasized. This study underscored the requirement for a holistic perspective to generate coe cients that permit the analysis of the utilization of natural resources considering environmental, economic and social dimensions in these systems.…”

The purpose of this work is to describe the creation process of the first long-term experimental platform designed for interdisciplinary studies of Silvopastoral Systems (SPS) in Uruguay. This experiment involves professionals from diverse fields working together to generate knowledge for sustainable agriculture. The focus is on understanding long-term interactions in SPS, emphasizing native ecosystem conservation and increased agricultural productivity. Covering 30 ha, this experimental platform incorporates three treatments, implemented in a randomized complete block design with three replications: 1) a natural grassland without trees, 2) a two-row SPS with 160 trees/ha, and 3) a four-row SPS with 240 trees/ha. The platform's design involves the exploration of variables such as aboveground biomass and botanical composition, microclimate, silviculture, livestock performance, soil carbon dynamics, ecosystem integrity index, monitoring ecological indicators such as amphibian and soil spiders, optimizing modeling and economic benefit and social aspects. This platform will allow us to understand the changes induced by the incorporation of trees in two different densities to livestock systems. We also expect to understand the best combination of activities to optimize the income of the farmers, considering the relevance of a positive impact on social aspects, such as increased demand of employment, adoption by farmers, and the interest of new generations.

“…Trees have a direct and pivotal in uence on the constituents of a SPS, rendering them fundamental in its strategic planning (Fedrigo et al, 2018). To ensure the e cacy, sustainability, and productivity of these integrated systems, it's basic the continuous measurement of the arboreal component throughout its productive life cycle.…”

“…Los datos mostraron una reducción de cerca de 2 °C en el pastizal del protocolo A, reflejando una de las ventajas de sistemas silvopastoriles como es el surgimiento de microclimas que influyen en las producciones al disminuir entre 2.1 y 3.8 °C la temperatura ambiental, aumentando así el rendimiento productivo, confort y bienestar animal (Castaño et al, 2014;Fedrigo et al, 2018).…”

El objetivo del estudio fue evaluar el comportamiento y respuesta fisiológica en pastoreo de vacas Brahman en arreglos silvopastoriles con árboles dispersos. El estudio se realizó en Puerto Nare, Antioquia, Colombia. Se tipificaron dos sistemas productivos: un sistema con revestimiento pertinente de sombra con árboles y arbustos discontinuos y un callejón central de árboles (protocolo A) y un sistema control con escasa cubierta de árboles (protocolo B). Cada sistema incluyó a 19 vacas Brahman con sus crías. Se registró menor temperatura ambiental en los potreros del protocolo A (p=0.04) y una frecuencia respiratoria mayor en las vacas del protocolo B (p=0.0001). No hubo diferen-cias en la ingesta de materia seca (p=0.40), pero hubo mayor tiempo dedicado al pastoreo nocturno en las vacas del Protocolo B (p=0.0017). Se concluye que los sistemas silvopastoriles con adecuada oferta de sombra permiten reducir la temperatura ambiente hasta en 2° C, propiciando mayor bienestar y comodidad a bovinos Bos indicus alojados en condiciones de trópico.

Botanical composition gradients in silvopastoral systems on temperate native grasslands of Uruguay

Silvopastoral systems may provide important production and environmental benefits. The loss of cool-season (C3) grasses from temperate grazed native grasslands is associated with selective grazing and excessive solar radiation that limit their survival. Silvopastoral systems integrate trees with grasslands that provide shade to both cattle and herbaceous plants, potentially favoring C3 species. There is limited information about the effect of trees on the species and functional composition of native grasslands in the Campos biome in South America. The objective of this study was to detect gradients in the botanical composition of grasslands as affected by changes in the shade associated with distance to the trees and cardinal orientation in three situations defined by the combination of soil and tree species (Prosopis on Solonetz, Acacia on Brunisols, and Eucalyptus on Brunisols). Soil cover of the herbaceous species under trees was recorded in double transects located in the four cardinal directions. In all situations there were changes in pasture composition in the different shaded regions (total shade, partial shade, or full sun). Under the canopy, there was an increase of cool-season grasses such as Bromus catharticus Vahl, Lolium multiflorum Lam., Stipa hyalina (Nees) Barkworth, and S. setigera J.Presl. At greater distances from trees, cover of warm-season grasses, such as Axonopus affinis Chase and Paspalum notatum Flueggé increased. These gradients suggest that trees in silvopastoral systems can increase the abundance of cool-season species and potentially improve the forage nutritive value of the native pasture.
