Zusammenhänge zwischen Reaktions-Zeigerwerten und bodenchemischen Parametern am Beispiel von Waldbodenvegetation

摘要: Some authors regard H + -activity (pH) in soils among other chemical factors of minor importance for plant life. Therefore it is investigated whether soil-pH or parameters like S-value Al/Ca-ratio correlate better with indicator values soil reaction (mR) derived from the floristic composition different forest sites. It found that on a local to regional scale, Al/Ca-ratios show closest correlation mR, while higher scale performs best results. pH almost ever parameter weakest correlation. The results are discussed background relevance life comparison cation activities Al-toxicity, Ca-availability etc. pH-dependent properties (NH 4 /NO 3 -ratio)
