摘要
the green manure promotes benefits on the chemical, physical and biological properties of soil. the experiment evaluated the effect of incorporation of differents green manure on the chemistry characteristics of a soil. experimental design used was a randomized block, with eight treatments and three replications. treatments were: calopogonium mucunoides, crotalaria juncea, crotalaria spectabilis, cajanus cajan, macrotyloma axillare, mucuna pruriens and pueraria phaseoloides and the treatment control (without leguminous)). evaluations of soil samplings were performed in 60 days after handling were performed. the results showed significant effects of the leguminous crop pueraria phaseoloides, c. juncea and c. spectabilis on the fertility of the soil, with significant increments of organic matter, exchangeable bases and in the base saturation.
