“…For OF2, OF5 and OF6, the maintenance of soil fertility is based mainly on the use of composted green waste with slow N release, generally spread before planting. This type of amendment is oriented by the direct vicinity of big cities and the absence of animal manure in the center of the Parisian basin, highly specialised in cash crop farming (Mignolet et al 2007;Anglade et al 2015a). OF3 recycles on-farm laying hen droppings, reducing its dependence to exogenous inputs to 5 kgN/ha/yr, less than 5 % of total N inputs.…”

“…For grain legumes (such as beans, lentils …), a standard NHI value of 0.75 was assumed (Anglade et al 2015b), except for green pulses for which we assumed a value of 0.5 Urbano Terron (2002). For forage legumes (clover, alfalfa …), we did not attribute NHI values, because they were only grown in cover crops serving as green manure and thus were not harvested.…”

“…We used the nitrogen soil surface balance (SSB) concept (van Beek et al 2003;Oenema et al 2003;de Vries et al 2011;Anglade et al 2015a) to assess the agronomic and environmental performance of the market gardening system. Extended over the entire crop rotation, the SSB is a way to explore the relationships between the mean harvested yield (Y) and the total N inputs (F) via organic fertilisers (X org ), biological nitrogen fixation (BNF), atmospheric depositions (Dep) and irrigation (Nirr).…”

Organic market gardening is often promoted by urban municipalities as a way to resource part of the food supply, creating new social links and protecting groundwater resources. The agronomical and environmental performance of six commercial organic market gardening farms supplying vegetables in Paris were evaluated and compared with other vegetable production systems. When expressed in terms of protein production, the yield of these systems appears rather low compared with the productive capacity of open-field organic cropping systems where vegetable production is inserted into rotation with other crops. Moreover, the requirement of producing infiltrated water meeting the drinking water standards seriously limits the allowable rate of fertilisation, thus limiting production. The data reported herein show that to supply the amount of vegetables required by the Paris agglomeration (12 million inhabitants) only by organic market gardening, 160,000-205,000 ha, i.e. 28-36 % of the agricultural area of the surrounding Ile-de-France region, would be required. We conclude that organic market gardening is only one of several other farming systems which can contribute to a re-localised supply of vegetables to large cities.

“…Dissolved silica concentrations were determined according to litho-morphological properties, distinguishing crystalline and sedimentary rocks. Nitrogen (nitrate) leaching flux was calculated based on a comprehensive analysis of the agricultural EUROSTAT databases and N surplus (Anglade et al, 2015) established with the GRAFS (generalized representation of agro-food systems) approach (Billen et al, 2014).…”

At the start of the PIREN-Seine program, organic pollution by the effluent of the Parisian conurbation was responsible for episodic anoxia in the lower Seine River, while nutrients from both point and diffuse sources are used to cause eutrophication, a nuisance for drinking water production from surface water and biodiversity. The implementation of the EU Water Framework Directive led to a drastic decrease of organic carbon, phosphorus and ammonium concentrations in surface waters starting in the early 2000s and to a reduction of the frequency and the amplitude of phytoplankton blooms. However, nitrate contamination from fertiliserintensive agriculture continued to increase or at best levelled off, threatening groundwater resources and causing unbalanced nutrient ratios at the coastal zone where eutrophication still results in harmful algal blooms. High-frequency O 2 data combined with models, which have been developed for 30 years, can help discriminate the contribution of auto-vs. heterotrophic metabolism in the CO 2 supersaturation observed in the Seine River. Despite the impressive improvement in water quality of the Seine River, episodic crises such as summer low-flow conditions still threaten the good ecological status of both river and coastal waters. Modelling scenarios, including further wastewater treatments and structural changes in agriculture and future changes in hydrology under climate changes, provide the basis for a future vision of the ecological functioning of the Seine River network.
