Ammonium nitrogen (N-NH₄) concentration in the calcisols of the Nikitsky Botanical Garden shows considerable spatiotemporal variation. This study has shown an extremely close correlation and corresponding linear relationships between nitrogen stores in the different soil layers and the average monthly temperature as well as between the logarithms of N-NH₄ concentration values and depth.

石灰石中铵态氮分布的规律

Nikitsky植物园的钙质溶胶中的铵态氮（N-NH ₄）浓度显示出相当大的时空变化。这项研究表明，不同土壤层中的氮存储量与月平均温度之间以及N-NH ₄浓度值的对数与深度之间具有极密切的相关性和线性关系。
