Agricultural soils are the main anthropogenic source of nitrous oxide (N 2 O), largely because nitrogen (N) fertilizer use. Commonly, N O emissions expressed as a function application rate. This suggests that smaller applications always lead to emissions. Here we argue that, global demand for agricultural products, agronomic conditions should be included when assessing Expressing in relation crop productivity (expressed above‐ground uptake: ‘yield‐scaled emissions') can express efficiency...
After significant increases in livestock productivity, China now needs to improve efficiency and environmental performance.
The high N inputs to agricultural systems in many regions 27 member states of the European Union (EU‐27) result leaching groundwater and surface water emissions ammonia (NH 3 ), nitrous oxide (N 2 O), nitric (NO), dinitrogen ) atmosphere. Measures taken decreasing these often focus at one specific pollutant, but may have both antagonistic synergistic effects on other emissions. model MITERRA‐EUROPE was developed assess interactions policies measures agriculture losses P balances a regional...
Increasing nitrogen (N) and phosphorus (P) inputs have greatly contributed to the increasing food production in China during last decades, but also increased N P losses environment. The pathways magnitude of these are not well quantified. Here, we report on use efficiencies at a national scale 2005, using model NUFER (NUtrient flows Food chains, Environment Resources use). Total amount “new” imported chain was 48.8 Tg 2005. Only 4.4.Tg reached households as food. Average crop production,...
The largest livestock production and greatest fertilizer use in the world occurs China. However, quantification of nutrient flows through manure management chain their interactions with management-related measures is lacking. Herein, we present a detailed analysis losses "feed intake–excretion–housing–storage–treatment–application" chain, while considering differences among systems. We estimated environmental loss from 2010 to be up 78% excreted nitrogen over 50% phosphorus potassium....
Transitions in Chinese agriculture resulted industrial animal production systems, disconnected from crop production. We analyzed side-effects of these transitions on total dissolved nitrogen (TDN) and phosphorus (TDP) inputs to rivers. In 2000, when were ongoing, 30%–70% the manure was directly discharged rivers (range for sub-basins). Before transition (1970) this only 5%. Meanwhile, numbers more than doubled. As a result, TDN TDP increased 2- 45-fold sub-basins) during 1970–2000. Direct...
Abstract. Grazing animals on managed pastures and rangelands have been identified recently as significant contributors to the global N 2 O budget. This paper summarizes relevant literature data emissions from dung, urine grazed grassland, provides an estimate of contribution grazing The effects emission are brought about by concentration herbage in dung patches, compaction soil due treading trampling. limited amount experimental indicates that 0.1 0.7% 3.8% is emitted atmosphere O. There no...
The nitrogen (N) and phosphorus (P) costs of food production have increased greatly in China during the last 30 years, leading to eutrophication surface waters, nitrate leaching groundwater, greenhouse gas emissions. Here, we present results scenario analyses which possible changes production-consumption for year 2030 were explored. Changes chain structure, improvements technology management, combinations these on supply environmental quality analyzed with NUFER model. In business as usual...
Animal manure contributes considerably to ammonia (NH3) and greenhouse gas (GHG) emissions in Europe. Various treatment technologies have been implemented reduce facilitate its use as fertilizer, but a systematic analysis of these has not yet carried out. This study presents an integrated assessment effects on NH3, nitrous oxide (N2O) methane (CH4) from management chains all countries EU-27 2010 using the MITERRA-Europe model. Effects implementing 12 nutrient recovery were further explored...
