Nutrient fluxes and retention in Andean raised-field agriculture: implications for long-term sustainability

tiwanaku and its hinterland : archaeology and paleoecology on an andean civilization • Washington, Dc • Published In 1996 • Pages: 169-179

Abstract
The authors conducted chemical and biological analyses along nine transects in different ecotones. The data from the transects and experimental fields is used to determine that '… the anthropogenic landscape of raised-field networks differentially retains mineral nutrients … as water circulates through the fields en route to the lake.' (page 169). And therefore, '[r]ehabilitation of raised fields can have ecological advanages …as well as economic advantages…' (Page 179).
