Description:	Studies on Oxisols in the Cerrado of Brazil have shown that mucuna, a common green manure, can provide much of the nitrogen required by a succeeding food crop. Such green manures, if effectively managed, appear to hold promise as a supplement or an alternative for fertilizer nitrogen in the Cerrado. This experiment, established as a companion study to the work in the Cerrado, sought to test similar green-manure management techniques for their suitability to soil and climate conditions in the Manaus region. The objectives were 1) to quatify the N supplied by green manures to com and rice, and 2) to evaluate the importance and availability of green-manure N to crops.
