This book is an essential reference source covering the chemical elements that are nutrients for plants or grazing animals. It deals with the concentrations and transformations of these elements in soils, grassland plants, and ruminant animals, particularly cattle and sheep. For each element, the following data are given: forms occurring in soil, factors that affect availability and concentration, uptake and distribution in grassland plants, role in animal nutrition, amounts and forms excreted by grazing animals, and concentrations needed by ruminant animals.

The population explosion that began in the 1960s has been accompanied by a decrease in the quality of the natural environment, e.g. pollution of the air, water and soil with essential and toxic trace elements. Numerous poisonings of people and animals with highly toxic anthropogenic Hg and Cd in the 20th century prompted the creation of the abiotic environment, mainly in developed countries. However, the system is insufficient for long-term exposure to low concentrations of various substances that are mainly ingested through food and water. This problem could be addressed by the monitoring of sentinels – organisms that accumulate trace elements and as such reflect the rate and degree of environmental pollution. Usually these are long-lived vertebrates – herbivorous, omnivorous and carnivorous birds and mammals, especially game species. This book describes the responses of the sentinels most commonly used in ecotoxicological studies to 17 trace elements.

This book is a remarkable work that brings together the most recent international research on grassland management, covering a broad range of topics and geographical areas. The different contributions explore the complex relationships between landscape, climate features, and soil fertility with the support of observational data and modeling. Clearly, this is a wide and multifaceted area of research that opens up new prospects for the management of a biome, which should no longer be considered only as a feed resource for domestic herbivore farming, but also—and above all—as a source of ecosystem services to society and a contributor to the sustainability of agriculture. Textbooks like this positively demonstrate the importance and significance of how grassland science, when viewed in this way, can make tangible the progress in understanding the complexity of grassland management and its current and future challenges.

Whilst the benefit of understanding the involvement of animals in excessive greenhouse gas release is a given it is also known that animal effluent contains nitrogenous compounds that can be recycled. The delegates to this conference explored all aspects of responsible farming methods with an accent on greehouse gas reduction.
