Organic agriculture can and should play an important role in solving future challenges in
producing food. The low level of external inputs combined with knowledge on sustainablity …

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 …

Optimising nitrogen (N) management improves soil fertility and reduces negative
environmental impacts. Mineral N fertilizers are of key importance in intensive conventional …

Environmental pressures posed through human activities are expected to further increase
due to growing population numbers and increasing per capita consumption. It will be crucial …

A life cycle assessment (LCA) of dairy systems in Nova Scotia was conducted to compare
environmental impacts of typical pasture and confinement operations. Data on material and …

Reactive nitrogen (N) flows (all forms of N except N 2) are greatly increasing worldwide. This
is mainly due to the ever larger use of inorganic N fertilizers used to sustain the growing food …

Ruminal fermentation products such as short-chain fatty acids (SCFA) and CO2 acutely
stimulate urea transport across the ruminal epithelium in vivo, whereas ammonia has …

Improved management of nitrogen (N) in agriculture is necessary to achieve a sustainable
balance between the production of food and other biomass, and the unwanted effects of N …

The aim of this study was to assess if dairy intensification is associated with increased
efficiency in food production, nutrient, and energy use. In-depth data from 12 high-input …

Even optimistic assumptions about population growth, agricultural productivity, and
potentially available cropland produce a grim image for the future food security and …
