Summary

Soil microorganisms caused considerable degradation of wheat stubbles under laboratory conditions. Mixtures of different organisms proved to be more efficient than individual organisms in degrading lignin, holocellulose and nitrogenous substances which constitute the major components in stubble. Lignin and holocellulose content in fresh stubble was about 25% and 60% of dry weight respectively. Degradation of these compounds caused an increase in simpler components like soluble carbohydrates. Degradation of nitrogenous substances (represented by 0.7% total nitrogen in fresh stubbes) caused accretion in the soluble nitrogen of the degraded product. In most cases, these products proved to be important in improving fertility of the soil thereby causing significant promotion of growth of crops like maize and rice.
