Abstract
Organic residues accumulate in a soil.or are broken down and disappear. in-conformity with a very mixed lot of local circumstances. and an analysis of a cultivated soil for carbon and nitrogen usually tells us very little about its state of fertility. It certainly does not yet afford guidance on policy in organic manuring.For that reason. agricultural chemists working to practical ends have not bothered much with precision measurements of these elements in soil. and the recorded data are scattered not very plentiful even for soils that have been much worked upon. and often seriously uncertain in accuracy. Most of the factors that govern soil organic matter however are also those that determine soil type and its modifications under tillage or pastoral management. and it is a reasonable expectation that with advancing security in the principles of soil classification. progress will be made towards the recognition of a "norm" for content and character of organic matter in particular soils.
