NPL01 Litterfall inputs to soil surface in watersheds with different fire treatments

Litter falling to the soil surface of tallgrass prairie was measured using 5 cm x 100 cm litterfall troughs. Mass, nitrogen, and phosphorus content were measured monthly or seasonally. Variables of interest include burning frequency and soil type.

高草草原（tallgrass prairie）土壤表面的凋落物沉降量，采用5 cm × 100 cm规格的凋落物收集槽（litterfall troughs）进行测定。研究人员对凋落物的干物质重、氮与磷含量按月度或季度开展测定。本数据集关注的变量包括燃烧频率与土壤类型。
