Fertilité des sols et minéralisation de l’azote : sous l’influence des pratiques culturales, quels processus et interactions sont impliqués ?
Résumé
Soil fertility and nitrogen mineralisation: what type of cultivation-related processes and interactions are involved? In this study, soil fertility is defined as the ability of soils to furnish necessary nutrients to plants. It is a consequence of the biological, chemical, and physical properties of soils and their interactions. The nitrogen cycle and its relationship with soil organic matter dynamics play a key role; the nitrogen cycle is linked to the carbon cycle by the activity of soil bacteria. Here, we describe the interactions between various biological, chemical, and physical processes that take place in the soil. It is thus possible to examine the effects of cultivation practices, such as limiting or eliminating ploughing, including temporary pastures in rotations, and destroying temporary pastures as part of the rotation cycle. One can also envision an agricultural approach that promotes the recycling of organic matter and the soil’s biological functions.
