The Skokloster classification is based on the assumption that the majority of acidification neutralization is due to base cation release from mineral weathering. It therefore considers the long-term neutralizing capacity of a soil on a scale of decades. Th作者: WAG 時間: 2025-3-22 22:17

Evidence of Current Soil Acidification in Spruce Stands in the Vosges Mountains, North-Eastern Franlow levels of Mg in the ecosystem, may explain this discrepancy. Since 1987, a general decrease of the (Ca. Mg.)/Al. ratio in soil solution was observed at both sites. These results are consistent with present day acidification of soils poor in weatherable minerals under spruce stands in the Vosges Mountains.作者: 種屬關(guān)系 時間: 2025-3-26 23:11 作者: jumble 時間: 2025-3-27 04:50 作者: CREST 時間: 2025-3-27 06:34 作者: 誤傳 時間: 2025-3-27 11:20 作者: Emg827 時間: 2025-3-27 15:20 作者: AORTA 時間: 2025-3-27 20:46
