Abstract
Since recent studies reveal citric acid to be favorable for estimating plant-available P in soils, we investigated if it can also be used for assessing other nutrients. According to our results, it provides stronger correlations with the tree nutrition for Mg (beech, spruce), Ca+K (beech) and Fe (spruce) than the standard methods for determining exchangeable cations. Thus, when estimating plant-available P by citric acid-extraction, these cations should be additionally measured in ICP analysis.
