Hog Island Soil Water Nutrient Chemistry 1990-1992

Soil water samples were collected at two depths (15 cm and 50 cm) with porus cup lysimeters from all dune and swale sites across the Hog Island Chronosequence. This included samples from N-fertilized areas on the dunes.

本研究借助多孔杯式渗漏计（porous cup lysimeters），在霍格岛时间序列（Hog Island Chronosequence）涵盖的全部沙丘与洼地样地中，于15厘米与50厘米两个深度采集土壤水分样品，样品包含沙丘上施氮区域的土壤水分样品。
