Summary The seasonal fluctuations and rotational differences in carbon‐nitrogen ratios are reported under irrigated rotational cropping in the Sudan Gezira. Statistical analysis shows that there are no rotational differences in carbon‐nitrogen ratios. Seasonal fluctuations in the ratio reflect the cropping period in the rotation and also display marked activity during the period of the year when it is very hot and dry.
