Net primary production (NPP) is a critical ecosystem property that researchers and land managers attempt to quantify across ecosystems globally. Although the belowground NPP (BNPP) component of total NPP often contributes 50% or more to total NPP, it is infrequently measured due to the amount of labor involved. Here, I present a rapid method to estimate BNPP or fine root production in rangelands using sequential or root ingrowth cores and modifications to existing root-washing methods. The details provided should allow anyone to estimate BNPP in rangelands worldwide with minimal investment in materials and labor.

技术说明:一种估算草地,灌木丛和森林中根系产量的快速方法

净初级生产(NPP)是生态系统的一项重要属性,研究人员和土地管理者试图在全球范围内对整个生态系统进行量化。尽管总NPP中的地下NPP(BNPP)成分通常占总NPP的50%或更多,但由于涉及的劳动量很少被测量。在这里,我提出了一种快速的方法,该方法可以使用顺序或根向内生长核以及对现有根系冲洗方法的修改来估算牧场中的BNPP或优良根系。提供的详细信息应使任何人都可以以最少的材料和劳动力投资来估算全球牧场的BNPP。
