The amount of carbon dioxide produced during incubation (3 weeks at 28°) of 18 soils (of varying texture and pH) treated with 1% cellulose was highly correlated with the total mineral nitrogen content of unamended soils after 3 weeks’ incubation. This ‘indirect incubation technique appears a convenient method for assessing the nitrogen status of soils, as there is no need to extract and determine mineral nitrogen.
