Description :
In a field experiment, the AA. investigated organic matter decomposition in nonsaline nonsodic Aquic Argiudoll, a nonsaline sodic Typic Natraquoll, nonsaline nonsodic Petrocalci Paleudoll and a saline sodic Typic Natralboll in the Pampa Deprimada, Argentina. The aims were to identify the degree of stabilization of organic matter by association with mineral particles in these soils and to follow in particular the fate of lignin in these soils. They measured organic carbon, total nitrogen and the extent of lignin alteration with soil depth and in various particle size fractions.
