Soil P and K availability defines below-ground biomass allocation of grass-legume leys (original) (raw)

Cong, W.-F.; Christensen, B.T. and Eriksen, J. (2018) Soil P and K availability defines below-ground biomass allocation of grass-legume leys. In:Proceedings, p. 33.

Summary in the original language of the document

Exploring the response of above- and below-ground biomass allocation to soil nutrient availability is crucial to reliably estimating root carbon (C) input and predicting long-term soil C dynamics. Despite this, belowground C input is often estimated by using yield-based allometric equations without considering the impacts of environmental factors or management practices such as fertiliser levels, which could lead to erroneous and uncertain estimates.
