Using nutrient budgets, it has been proven that atmospheric deposition of Mg and Ca sustains the fertility of forest ecosystems on base-poor soils. However the fate of this nutrient input within the ecosystem was presently unknown. Our hypothesis is that the biological cycling of these nutrients is very rapid and conservative to prevent further Mg and Ca losses most especially in ecosystems on base-poor...
Accurate nutrient budgets in forest ecosystems are needed in order to plan sustainable forest management on poor soils. Such budgets require precise measurements of water and nutrient leaching through the soil. This study aims to characterize the hydrological processes and compute hydrological budgets occurring in a very poor and acidic soil under a 30-year-old beech stand in the Morvan Mountains...
Background and aims The sustainability of forest ecosystems may be at stake especially in forests on base-poor soils due to reduced nutrient deposition and intensified silvicultural practices. Understanding nutrient availability and cycling is therefore essential to manage forest soil fertility. This study aims to assess in a beech plot Mg and Ca vertical transfer in soil and root uptake using an...
