Field and laboratory methods for grassland and animal production research.

Book cover for Field and laboratory methods for grassland and animal production research.

Description

This book brings together a range of methods used to study grasslands (both temperate and tropical) and ruminant performance, including: grassland vegetation and its measurement; pattern analysis in grassland and animal production systems; modelling pasture and animal production; measuring botanical composition of grasslands; measuring sward structure; plant population dynamics in grasslands; meas...

Measuring sward structure.

Techniques used for the measurement of sward structure are reviewed with special consideration of vertical and horizontal structure. Basic factors affecting sward structure, such as herbage growth and grazing, are discussed. Methods for measuring vertical structure described include clipping, point quadrat, foliage orientation methods, light transmission methods, near-infrared reflectance methods, and laser methods. Sampling methods, scale and pattern, and geo-referencing are discussed in relation to horizontal structure.
