Nitrogen (N) is crucial for crop productivity. However, nowadays more than half of the N added to cropland lost environment, wasting resource, producing threats air, water, soil and biodiversity, generating greenhouse gas emissions. Based on FAO data, we have reconstructed trajectory followed, in past 50 years, by 124 countries terms yield total nitrogen inputs (manure, synthetic fertilizer, symbiotic fixation atmospheric deposition). During last five decades, response agricultural systems...
An integrated modeling approach was used to connect socioeconomic factors and nutrient management river export of nitrogen, phosphorus, silica carbon based on an updated Global NEWS model. Past trends (1970–2000) four future scenarios were analyzed. Differences among the for in agriculture a key factor affecting magnitude direction change DIN export. In contrast, connectivity level sewage treatment P detergent use more important differences DIP particulate calculated decrease all scenarios,...
The Millennium Ecosystem Assessment scenarios for 2000 to 2050 describe contrasting future developments in agricultural land use under changing climate. Differences are related the total crop and livestock production efficiency of nutrient agriculture. with a reactive approach environmental problems show increases N P soil balances all developing countries. In proactive attitude, decrease no change or slight increase. Europe North America, balance will decline scenarios, most strongly...
Livestock production systems currently occupy around 28% of the land surface European Union (equivalent to 65% agricultural land). In conjunction with other human activities, livestock affect water, air and soil quality, global climate biodiversity, altering biogeochemical cycles nitrogen, phosphorus carbon. Here, we quantify contribution these major impacts. For each environmental effect, is expressed as shares emitted compounds used, compared whole sector. The results show that sector...
Nitrogen (N) limits crop and grass production, it is an essential component of dietary proteins. However, N mobile in the soil-plant system can be lost to environment.

The nitrogen cycle of pre-industrial ecosystems has long been remarkably closed, in spite the high mobility this element atmosphere and hydrosphere. Inter-regional international commercial exchanges agricultural goods, which considerably increased after generalization use synthetic fertilizers, introduced an additional type mobility, nowadays rivals atmospheric hydrological fluxes intensity, causes their enhancement at local, regional global scales. Eighty-five per cent net anthropogenic...
Management of nitrogen (N) inputs into agricultural systems is increasing interest due to the intensive use synthetic fertilizers in modern cash crop systems, which has caused considerable environmental damage, including nitrate contamination surface and groundwater, eutrophication coastal marine areas emission greenhouse gases. The legumes grown rotations or intercropping nowadays regarded as an alternative sustainable way introducing N low‐input cropping systems. In order develop a simple...
Seasonal succession of diatoms and Chlorophyceae have been analyzed in the Seine River system (France), which is characterized by a temperate oceanic hydrological regime high nutrient enrichment. Phytoplankton development invariably initiated decrease discharge spring. When this occurs early spring, bloom dominated that severely deplete silica, regular increase their biomass observed along river continuum from headwaters to estuary.
