e-infrastructure Roadmap for Open Science in Agriculture

A bibliometric study

The e-ROSA project seeks to build a shared vision of a future sustainable e-infrastructure for research and education in agriculture in order to promote Open Science in this field and as such contribute to addressing related societal challenges. In order to achieve this goal, e-ROSA’s first objective is to bring together the relevant scientific communities and stakeholders and engage them in the process of coelaboration of an ambitious, practical roadmap that provides the basis for the design and implementation of such an e-infrastructure in the years to come.

This website highlights the results of a bibliometric analysis conducted at a global scale in order to identify key scientists and associated research performing organisations (e.g. public research institutes, universities, Research & Development departments of private companies) that work in the field of agricultural data sources and services.

Nitrous oxide (N(2)O) emissions from grazed pasture soils represent a significant source of atmospheric N(2)O. Nitrous oxide is produced by transformations of nitrogen from cattle excrements, urine and fertilizers entering the soil. Specific conditions are necessary for emissions of N(2)O and these emissions are both spatially and temporally highly variable. Spatial, and in some extent temporal variability, is due to the complex effect of nitrogen input, pasture management and environmental conditions (e.g., aeration and water status, pore space and pore size distribution, available carbon and mineral nutrients concentration, pH and other soil chemical properties, as well as microbial communities abundance and diversity) on N(2)O emissions and all this makes estimation of emissions very difficult. Several types of environments or events characterized by potentially high N(2)O production and emissions (= emission hot spots) can be distinguished in the livestock farming system. These include camping areas, drinking sites, feedlots, shade areas, footpaths, dung and urine patches (where combined effects of nutrients in urine, dung and compaction occur resulting in creating conditions for high nitrification and denitrification rates). Here we propose overwintering areas, that is pasture sites where cattle is located in high stock densities for a relatively long period during winter season (where severe damage of plant cover is common and the effects typical for the above camping areas and other hot spots are even reinforced) as another type of hot spots for N(2)O emissions. Due to the overgrazing effect, damage of vegetation and high stock density, as well as high N-inputs in excrements and lower utilization of deposited N by plants in a cold period, cattle overwintering areas appear to have a large potential for accelerated microbial N transformations and thus gaseous losses. This contribution examines various aspects related to the production of NO and its emission from the soil of cattle-grazed pasture sites, aiming to identify its major sources as well as environmental soil conditions favourable for N(2)O production (= emission hot spots), as well as to summarize mitigation strategies for N(2)O emissions. In particular, it is focused on the cattle overwintering areas, representing specific and often significant emission hot spots. Relevant measures to decrease N(2)O fluxes from the grazed grasslands are presented. However, practical options to decrease N(2)O emissions seems to be rather limited due to a number of reasons, including a limited knowledge on intrinsic mechanisms regulating N(2)O production in the pasture soils.
