A Comparison of Frontal, Continuous, and Rotation Grazing Systems [PDF]

Journal of Range Management, 1994
Two 2-year trials were conducted to evaluate and compare frontal, continuous, and 2-paddock rotation grazing systems on 'Plains' Old World bluestem (Bothriochloa ischaemum (L.) Keng.). Frontal grazing allows livestock a continuous opportunity to graze fresh forage via a livestock-pushed, sliding fence which allocates and controls grazing within a ...

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

Animals, 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 ...

Phosphorus pools in soils under rotational and continuous grazed pastures [PDF]

Agrosystems, Geosciences & Environment, 2020
AbstractPhosphorus loss from intensively grazed pastures is an ongoing concern in agricultural watersheds. We investigated P pools in fields managed as continuous (stocking rate of 3.55 animal unit [AU] ha–1) and rotational (stocking rate of 2.56 AU ha–1) cattle grazing pastures.

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

Applied Sciences, 2023
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.
