Understanding the Dynamics of Sex-Specific Responses Driven by Grassland Management: Using Syrphids as a Model Insect Group

Land
Grassland ecosystems, managed by various grassland managements strategies, are the world’s most important land use. However, insect’s sex-specific responses within the context of grassland management have never been considered before.

Nitrogen management on large organic dairy farms [PDF]

, 2009
Large dairy herds need much grassland near the farm. Utilisation and losses of nitrogen in such grass-intensive crop rotations can be controlled by management: In grassland, grazing days or fertiliser input can be reduced, and following grassland ...

Flooding Length Mediates Fencing and Grazing Effects on Soil Respiration in Meadow Steppe

Plants
Grassland management affects soil respiration (Rs, consists of heterotrophic respiration and autotrophic respiration) through soil micro-ecological processes, such as hydrothermal, plant root, organic carbon decomposition and microbial activity. Flooding,

Proposition of an index of intensity of grass use [PDF]

, 2013
A. The widely used concept of intensity of grassland management can be defined according to the fertilization level and defoliation frequency for mown meadows or to the stocking rate for pastures.

The role of grazing management practices and tussock-forming plants on grassland birds in the Argentine Pampas

Discover Conservation
The structure of vegetation significantly impacts grassland birds. In temperate Southeastern South America (SESA), different cattle grazing practices shape grassland vegetation structure, influencing bird abundance and richness. We studied SESA grassland

The use of indirect methods for the prediction of lucerne quality in the first cut under the conditions of Central Europe

Czech Journal of Animal Science, 2010
The goal of this study was to compare the growing degree-days (GDD) and predictive equations for alfalfa quality (PEAQ) for the prediction of lucerne quality and to test their accuracy and suitability in the first cut period in Central Bohemia.
