This manuscript describes the natural soil amendments used in agriculture, which are
divided into three groups: organic, organic-mineral, and mineral amendments. It also …

Nitrogen isotopic studies have the potential to shed light on the structure of ancient
ecosystems, agropastoral regimes, and human-environment interactions. Until relatively …

Slurry, farmyard manure and poultry manure are an inevitable consequence of livestock
products generated from housed animals. These manures are recycled back to land for …

Sustainability in agriculture means the inclusion of several aspects, as sustainable
agriculture systems must not compromise not only their ability to satisfy future needs by …

Livestock manure contributes considerably to global emissions of ammonia (NH 3) and
greenhouse gases (GHG), especially methane (CH 4) and nitrous oxide (N2O). Various …

This book deals with the concentrations and transformations of nutrient elements in soils,
grassland plants and ruminants, particularly sheep and cattle. Data are restricted to those …

Emissions of ammonia to the atmosphere are considered a threat to the environment and
both United Nation treaty and European Union legislation increasingly limit emissions …

Greenhouse gas (GHG) emissions from post-consumer waste and wastewater are a small
contributor (about 3%) to total global anthropogenic GHG emissions. Emissions for 2004 …

Reduction of nitrogen loss in animal production requires whole-farm management. Reduced
loss from one farm component is easily negated in another if all components are not equally …

Manure management systems are conducive to nutrient and carbon losses, but the
magnitude of the loss highly depends on the nutrient element, the manure management …
