Sward lifting in compacted grassland: effects on soil structure, grass rooting and productivity
Soil and Tillage Research, 2018 Soil compaction can impair the productivity of permanent grassland. A way to ameliorate compaction in the topsoil (0–30 cm), without destroying the sward, is soil loosening by sward lifting. To explore the potential of this form of non-inversion tillage,

Drone‐based structure‐from‐motion photogrammetry captures grassland sward height variability
Journal of Applied Ecology, 2018 1. Grasslands deliver a range of ecosystem services, including: the provision of food and, biodiversity; and regulation of soil carbon storage and hydrology.

Austral Ecology, 2006 The grass layer of savannas is characterized by strong temporal and spatial heterogeneity in the quantity and quality of forage. Besides this, there is strong variation in other aspects of sward structure, here defined as sward chemistry, morphology ...

Influence of sward structure on daily intake and foraging behaviour by horses
Animal, 2010 The spatial heterogeneity of grasslands determines the abundance and quality of food resources for grazing animals. As plants mature, they increase in mass, which allows greater instantaneous intake rates, but the cell wall concentrations increase too, reducing diet quality.

Mechanistic simulation of the vertical structure of mixed swards
Ecological Modelling, 2002Abstract The vertical structure is an important feature of mixed swards, as it influences the inter-species competition for light, as well as the patterns of grazing. Although the experimental measurement of the vertical sward structure is relatively straightforward, the mechanistic and dynamic modelling of the leaf density and lamina density ...

Livestock Science, 2005 International audienceFrench wet grasslands support important populations of lapwings and others waders. Grazing management is a key issue in the use of grasslands by these birds since they are very sensitive to sward structure (height and heterogeneity).

Structure of Tall Fescue Swards and Intake of Grazing Cattle
Agronomy Journal, 1990AbstractModels of grazing systems need logic that estimate herbage intake of livestock from physical and chemical properties of the sward. Changeover designs were used to study the effects of sward structure of tall fescue (Festuca arundinacea Schreb. cv. Kenhy) on ingestive behavior of grazing cattle. Fourteen (Tl), 21 (T2), and 28 (T3) days of growth
