Abstract

International audience; The creation of an environmental tool diagnosis from existing modules in other models in order to contribute to improve the nitrogen management. Did the simplification of soil description, in terms of horizons number and of the shape’s curve of root profile in the French model of culture STICS, allows us to simulate correctly the quantity of leaching nitrogen?. The main objective is to feign the consequences of the variations of the environment (climatic parameters and soil properties) on the system of culture on agricultural plot production (wheat, corn and mustard) and on the environment (nitrogen leaching).

Abstract

Agricultural production systems around the Mediterranean basin rely mostly on rainfed agriculture in hilly watersheds, although some irrigation is sustained downstream of water reservoirs. With climate change and increasing demand for water, most commonly cultivated species, particularly cereals, are exposed to high risks of water shortages during the growing season. Under such threats, managing agricultural activities, for optimum water use, requires a good assessment of crop actual evapotranspiration (ET), a major term of both land surface energy and water balances.

Abstract

Estuaries are important nutrient filters along the land-ocean continuum. However, the role of benthic diagenesis is still poorly quantified. Estuarine sediments are important environments regulating carbon, nutrient, metal, and sulfur fluxes.
