Detailed investigation of organic matter components in extracts and drainage waters from a soil under long term cultivation

► Organic fractions isolated from a soil in long term cultivation. ► Also isolated from drainage water from the soil. ► Fractionation of extracts using a novel resin procedure. ► Sugar and amino acids and other functionalities determined via solid state NMR. ► Comparison of the composition of the fractions from the soil and drainage water. ► Comparison of organic fractions from cultivated soil with similar grassland fractions.
