门多龙研究区土壤样品中总钙的化学分析表明，它们的钙含量很低。由于钙的含量很低，如果采伐胸径大于20 cm的所有树木的茎材和树枝，将导致生态系统中50 cm深度以下的钙损失约19%。这一发现是基于对土壤中叶面含量和交换性钙含量的早期分析结果而没有预料到的。
Chemical analysis of total calcium in soil samples from Mendolong research area revealed that they had a very low calcium content. The content was so low that the harvesting of stemwood and stembark from all trees larger than 20 cm DBH should result in the loss of about 19% of all calcium in the ecosystem down to 50 cm depth. This finding was not expected based on earlier results of analyses of foliar contents and contents of exchangeable calcium in the soil.
