Estimating the global influence of Cover Crops on ecosystem service indicators in croplands with the LPJ-GUESS model
Listed in National Center for Atmospheric Research
Cover crops (CCs) can improve soil nutrient retention and crop production while providing climate change mitigation co-benefits.
Description
However, quantifying these ecosystem services across global agricultural lands remains inadequate. Here, we assess how the use of herbaceous CCs with and without biological nitrogen (N) fixation affects agricultural soil carbon stocks, N leaching, and crop yields, using the dynamic global vegetation model LPJ-GUESS.
The model performance is evaluated with observations from worldwide field trials and modeled output further compared against previously published large-scale estimates. LPJ-GUESS broadly captures the enhanced soil carbon, reduced N leaching, and yield changes that are observed in the field. Globally, we found that combining N-fixing CCs with no-tillage technique could potentially increase soil carbon levels by 7% (+0.32 Pg C yr(-1) in global croplands) while reducing N leaching loss by 41% (-7.3 Tg N yr(-1)) compared with fallow controls after 36 years of simulation since 2015.

This integrated practice is accompanied by a 2% of increase in total crop production (+37 million tonnes yr(-1) including wheat, maize, rice, and soybean) in the last decade of the simulation. The identified effects of CCs on crop productivity vary widely among main crop types and N fertilizer applications, with small yield changes found in soybean systems and highly fertilized agricultural soils. Our results demonstrate the possibility of conservation agriculture when targeting long-term environmental sustainability without compromising crop production in global croplands.
