Abstract

Grassland conversion is a common practice in leyarable cropping systems The effects of such a disturbance on soil organic matter status and its consequences for biogeochemical cycles in terms of soil organic matter SOM dynamics remain poorly understood We investigated changes occurring in soil organic carbon and nitrogen content bulk chemical composition and in lignin as well as carbohydrate signature during 2 years after grassland conversion into arable land Our results showed a rapid SOM decrease in the first few months after the conversion The bulk chemical composition as seen by solidstate 13C NMR spectroscopy was similar under grassland and arable land whereas different landuse had an impact on the contribution of plant litter compounds to SOM SOM of arable soil had higher lignin contents and lower contents of noncellulosic neutral carbohydrates than grassland soil After grassland conversion the most prominent change was an increase of the SOM’s content of noncellulosic carbohydrate above the contents recorded for grassland or arable land Principal component analysis indicated that SOM chemical characteristics of converted grassland even after 2 years are similar to those of initial grassland We conclude that the chemical composition of SOM is less susceptible to rapid change and that reinstallation of grassland within some years will safeguard the initial SOM status in leyarable rotationsWe acknowledge the financial support of the French ministry of ecology energy sustainable development and land management for financial support under the framework of the GESSOL program ‘COSMOFLUX’ Gérard Bardoux and Xavier Charrier are acknowledged for technical support
