“…However, considering that both treatments have the same grazing intensity, given the additional decrease in pasture height in the P2UD, a lower pasture growth rate can be inferred, which could be attributed to the application of dolomitic lime. According to Carvalho [47], the application of dolomitic lime in some soils can increase the production of dryland pastures up to five times. In previous work carried out, by our team in this test field, there was a positive effect of liming in the soil, although very slow, on pH and the Mg/Mn ratio.…”

The objective of this study was to determine how application with dolomitic limestone and grazing type (continuous or deferred) affect sheep grazing location and feed preference when the pasture growth rate is maximum. A 4ha field was divided into 4 plots: P1 and P2- without application of dolomitic limestone, continuous (CG) and deferred grazing (DG), respectively; P3 and P4- with application of dolomitic limestone, DG (1AUE), and CG (2.4 AUE), respectively. In DG, animals were placed and removed from the plots depending on the height of the pasture. In each plot, 12 georeferenced sampling points were identified. Throughout the pasture's vegetative cycle (autumn, winter, spring, and early summer) several measurements of pasture height and cut were carried out. From the beginning of March to the beginning of June, animal behavior was observed, by trained observers, through binoculars on six dates. Animals' activity grazing and location was recorded. The results show that: (i) the application of dolomitic limestone combined with CG provided higher values of pasture height; (ii) there were no significant differences in pasture quality between treatments; (iii) Deferred grazing led to 50% more sheep grazing days than continuous grazing; (iv) there were no significant differences in soil compaction between CG and DG; (v) the type of grazing and the treatment with dolomitic limestone did not seem to change the grazing pattern between treatments. This work contributes to understanding the relationships between different types of grazing in dryland pastures, with and without application of dolomitic limestone, and preferred grazing locations for sheep. This work could help agricultural managers make more informed decisions with the aim of promoting the sustainable intensification of livestock production in the Montado ecosystem.

“…The recommended process for reclaiming pastures in the Mediterranean region and increasing their productivity consists of increasing soil fertility by applying phosphate fertilizers and correcting Mn toxicity and soil acidity [41,68,69]. The excessive application of nitrogen fertilizers to pastures, or the application of N at less favorable times of the year, increases nitrate leaching and phosphate (PO 4 ) adsorption on soil particles, which eventually leads to surface and groundwater pollution and the eutrophication of surface water bodies [70].…”

“…Correction for the acidity and associated toxicities of aluminum (Al) and Mn and P can allow for five-fold increases in pasture productivity [69]. Sometimes, the focus is on the needs of the animal without considering the needs of the plants and the importance of of root reserves so that they can quickly regrow after a period of grazing [58].…”

“…From an economic standpoint, pasture is essential, since a forage unit (UF) obtained from pastured grass costs only 15 to 20% of the same UF obtained from commercial concentrate feed [71]. Carvalho [69] also states that the importance of improved permanent pasture results from the fact that it is arguably the cheapest food for ruminant animals.…”

Montado Mediterranean Ecosystem (Soil–Pasture–Tree and Animals): A Review of Monitoring Technologies and Grazing Systems

et al. 2023

View full text Add to dashboard Cite

Montado is an agro-silvo-pastoral ecosystem characteristic of the south of Portugal and called Dehesa in Spain. Its four fundamental components—soil, pasture, trees, and animals—as well as the climate make Montado a highly complex ecosystem. This review article provides an overview of the state of the art of Montado from the point of view of the agro-silvo-pastoral ecosystem and the scientific work carried out in this context. Thus, the aim is: (i) to describe and characterize the Montado ecosystem, as an agro-silvo-pastoral system; (ii) to reveal experimental tests carried out, technologies used or with the potential to be used in the monitoring of Montado; (iii) to address other technologies, carried out in similar and different agro-silvo-pastoral ecosystems from south Portugal. This review consists of three chapters: (a) components of Montado and their interactions; (b) advanced technologies for monitoring Montado; (c) grazing systems. No review article is known to provide an overview of Montado. Thus, it is essential to carry out research on grazing and its effects on the soil and pasture in the Montado ecosystem.
