Properties and composition of soil organic matter in matter in forest and arable soils of Schleswig-Holstein. 2. Litter and humic compounds in mineral horizons
Zeitschrift fur Pflanzenernahrung und Bodenkunde 159(1): 61-68
Organic matter composition is an important soil constituent with regard to function in soil ecosystems. Litter and humic compound contents from approx. 100 mineral soil investigations are presented. The soil horizons are divided into four groups (Ah, Ap, M, Bh) in order to compare the soil OM quality. Ap and Ah horizons showed a similar litter and humic compound distribution. Structural differences in the humic compound fractions were visible with CPMAS 13C-NMR.
