Nova Vida Ranch, Land Use Change: Forest-to-pasture chronosequence

Objective
Changes in soil organic matter and chemical characteristics by the introduction of cultivated pasture in a chronologically - we used soil δ13C distributions to determine the origin of soil C and to infer changes to soil C cycling patterns after forest clearing
Description
A native forest (Amazon Forest, as reference) and six pasture sites established at different times in Rondônia, Brazil
