A study was made to determine the long-term effect of two cropping systems and various fertilizer treatments on organic carbon, nitrogen and some of the carbohydrate constituents in Breton plot soils.Organic carbon, nitrogen, hexose, pentose, uronic acid, hexosamine and hexosamine-N contents were significantly greater in soils from plots in a five-year rotation of grains and legumes than in a wheat–fallow sequence. The proportion of organic carbon in the form of hexose did not differ significantly in either of the cropping systems, but the values for pentose, uronic acid and hexosamine were markedly greater in the five-year rotation plot soils.The contents of organic carbon, nitrogen and carbohydrate materials in soils increased considerably following the manure and fertilizer applications, whereas lime had no effect. Manure and fertilizer treatments also appeared to increase markedly the proportion of organic carbon present as hexose and hexosamine.

Abstract. Retardation of soil organic carbon (SOC) decay after nitrogen addition to litter or soil has been suggested in several recent studies and has been attributed to a retardation in lignin decay. With our study we tested the long-term effect of mineral nitrogen fertilization on the decay of the SOC component lignin in arable soil. To achieve this, we tracked 13C-labeled lignin and SOC in an arable soil that is part of a 36-year field experiment with two mineral nitrogen fertilization levels. We could show that nitrogen fertilization neither retarded nor enhanced the decay of old SOC or lignin over a period of 36 years, proposing that decay of lignin was less sensitive to nitrogen fertilization than previously suggested. However, for fresh biomass there were indications that lignin decay might have been enhanced by nitrogen fertilization, whereas decay of SOC was unaffected. A retardation of SOC decay due to nitrogen addition, as found in other experiments, can therefore only be explained by effects on lignin decay, if lignin was actually measured.
