SummaryA scheme on humus formation has been proposed. This is as follows: Lignin/carbohydrates, the chief sources of C for the microorganisms are first broken down by extracellular enzymes into smaller units. Soluble units are absorbed into the microbial cell where part of them are converted to phenols/quinones. These together with oxidising enzymes are discharged into the environment where they polymerise by a free radical mechanism. The formation of FA (fulvic acids) has also been explained… Expand
