Soil acidification

Bosque de pinos al lado del mar en el Sur de España. El pino como planta es un agente acidificador del suelo, lo que indirectamente impide que otras especies colonicen el suelo

En Europe, les efforts de diminution des intrants et retombées acides (fuel, gaz désoufrés, recul du charbon) ont porté leurs fruits (pour le SO2 et certains COV notamment, et moindrement pour les NOx (à cause des transports et des engrais), et NH3). Les dépassements de la « charge crititique » de retombées acide sont en diminution (unité : eq ha-1a-1). Attention, sur cette carte de l'Agence européenne pour l'environnement, les valeurs pour 2010 (carte de droite) étaient les valeurs-cibles prévues par l'adhésion à la mise en œuvre de la directive NEC (ces cibles peuvent ne pas avoir été atteintes)[2].

Soil acidification is the buildup of hydrogen cations, also called protons, reducing the soil pH. This happens when a proton donor gets added to the soil. The donor can be an acid, such as nitric acid and sulfuric acid (these acids are common components of acid rain). It can also be a compound such as aluminium sulfate, which reacts in the soil to release protons. Many nitrogen compounds, which are added as fertilizer, also acidify soil over the long term because they produce nitrous and nitric acid when oxidized in the process of nitrification.
