Phosphorus pools in soils under rotational and continuous grazed pastures

Agrosystems, Geosciences & Environment, 2020
Phosphorus 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

Climate Effects on Tallgrass Prairie Responses to Continuous and Rotational Grazing

Agronomy, 2019
Cattle grazing is an important economic activity in the tallgrass prairie systems in the Great Plains of the United States. Tallgrass prairie may respond differently to grazing management (e.g., high and low grazing intensity) under variable climate ...

Produção estacional, índice de área foliar e interceptação luminosa de cultivares de alfafa sob pastejo Seasonal yield, leaf area index and light interception of alfalfa cultivars under grazing

Pesquisa Agropecuária Brasileira, 2004
A alfafa (Medicago sativa L.) pastejada pode promover redução de custos de alimentação de ruminantes, mas o desempenho agronômico de cultivares sob pastejo no Brasil ainda é pouco conhecido.

Low-Intensity, High-Frequency Grazing Strategy Increases Herbage Production and Beef Cattle Performance on Sorghum Pastures

Animals, 2021
We assessed the effects of high-intensity and low-frequency (HILF) vs. low-intensity and high-frequency (LIHF) grazing on herbage production and performance of beef cattle grazing sorghum pastures.

Fluxo de biomassa aérea em azevém anual manejado sob duas intensidades e dois métodos de pastejo Aerial biomass fluxes in an Italian ryegrass managed under two grazing intensities and two stocking methods

Revista Brasileira de Zootecnia, 2007
O experimento foi conduzido com o objetivo de avaliar a influência de duas intensidades (moderada e baixa) e de dois métodos de pastejo (lotação contínua e rotacionada) no fluxo de biomassa aérea de azevém, medido por meio dos fluxos de crescimento ...

The impact of rotational grazing on biomass characteristics in boreal alluvial meadows [PDF]

Journal of Central European Agriculture
Northern Boreal alluvial meadows are semi-natural habitats that require extensive management. They also have lower productivity as compared to cultivated grasslands. The subsidies for keeping meadow habitats open are currently activity-based, not results-

ENERGY ESTIMATE AND CARBON STOCK IN SHORT-ROTATION EUCALYPTUS STANDS [PDF]

CERNE, 2016
ABSTRACT The use of biomass as an alternative energy source has been gaining attention because of its energy characteristics and environmental contribution and because it is renewable in short production periods. The aim of the present study was to evaluate the biomass production and carbon sequestration of eucalyptus grown under different conditions ...

Soil Macronutrient Responses in Diverse Landscapes of Southern Tallgrass to Two Stocking Methods

Agronomy, 2019
Macronutrient (N, P, S, K, Ca, and Mg) availability and distribution in soils of grassland ecosystems are affected by diverse factors, including landscape position, climate, and forms of management.

Does first and last stocking could “fits” Campos grassland structure to improve beef cattle production?

Ciência Rural, 2022
: This study evaluated the structure of vegetation and the performance of rearing heifers and cull cows in Campos grasslands managed in the rotational stocking method with first-last stocking in the spring-summer period.
