The results of analyses from the experiment Station at Sainte-Anne, Martinique, F.W.I., on Vertisols, emphasize the importance of nitrogen compounds in the formation of humic substances and in the development of a stable structure under an alternate sorghum cultivation. The carbon-nitrogen interaction suggests the existence of a characteristic organization of the organic system. Such organization can be used for a better efficiency of farming systems.
