Long-term ecological research in southern Brazil grasslands: Effects of grazing exclusion and deferred grazing on plant and arthropod communities [PDF]

open access: yesPLoS ONE, 2020
Grazing exclusion may lead to biodiversity loss and homogenization of naturally heterogeneous and species-rich grassland ecosystems, and these effects may cascade to higher trophic levels and ecosystem properties.

Effect of Sheep Grazing, Stocking Rates and Dolomitic Limestone Application on the Floristic Composition of a Permanent Dryland Pasture, in the Montado Agroforestry System of Southern Portugal [PDF]

open access: yesAnimals, 2022
The Montado is a complex agroforestry–pastoral ecosystem due to the interactions between soil–pasture–trees–animals and climate. The typical Montado soil has an acidic pH and manganese toxicity, which affect the pasture’s productivity and pasture ...

Impact of Deferred Versus Continuous Sheep Grazing on Soil Compaction in the Mediterranean Montado Ecosystem

open access: yesAgriEngineering, 2023
Deferred grazing (DG) consists in adapting the number of animals and the number of days grazed to the availability of pasture. Compared to continuous grazing (CG), which is based on a permanent and low stocking rate, DG is a management strategy that aims

Model Development for a Deferred-Grazing System [PDF]

open access: yesJournal of Range Management, 1973
Highlight: A model of the early growth of an annual pasture and liveweight response of grazing sheep was built using first order differential equations to study the practice of deferred grazing. The dynamic behavior of the system over time was simulated by solving the equations on a computer.

Effect of Increasing Species Diversity and Grazing Management on Pasture Productivity, Animal Performance, and Soil Carbon Sequestration of Re-Established Pasture in Canadian Prairie [PDF]

open access: yesAnimals, 2019
The objective of the study was to determine the effect of type of pasture mix and grazing management on pasture productivity, animal response and soil organic carbon (SOC) level.

Influence of deferred grazing on vegetation dynamics and livestock productivity in an Andean pastoral system [PDF]

open access: yesJournal of Applied Ecology, 2004
Summary Management recommendations intended to reduce rangeland degradation and increase livestock productivity often assume equilibrium conditions wherein vegetation and herbivore dynamics are tightly coupled. Recent research in Africa, Asia and North America, however, suggests that the dynamics of some arid systems are driven more by precipitation ...

Agronomic and nutritional characteristics of Massai grass subjected to deferred grazing and nitrogen fertilization

open access: yesSemina: Ciências Agrárias, 2017
This study aimed to evaluate the agronomic characteristics and nutritional value of Massai grass (Megathyrsus maximus ‘Massai’) pastures fertilized with different nitrogen levels and subjected to deferred grazing.

How does the initial sward height and the grazing period influence the spatial variability of vegetation in deferred signal grass pastures?

open access: yesBioscience Journal, 2022
The objective of this study was to evaluate the spatial variability of structural characteristics of deferred pastures of Brachiaria decumbens cv. Basilisk (signal grass) subjected to associations of sward heights (10, 20, 30, and 40 cm) at the beginning
