On the other hand, for corn, it was carried out in all treatments (100E; 100A, 50E:50A; 75E:25A – 75% of eucalyptus + 25% black-wattle and 25E:75A – 25% of eucalyptus + 75% of black wattle). The delimitation adopted was the one of a randomized block with three replications. The magnitude of the nutrient pool in the agrossilvicultural systems biomass was: N> K > Ca > Mg > P > S, for macronutrients, and Mn > Fe > Zn > B > Cu, for micronutrients. Due to the great export of nutrients through the corn harvest, residues should be kept and it is necessary to make a nutritional reposition, mainly with P, N, K, S and Zn in the following crops, because of the higher amount that are exported with the extraction of the corn tang, which reaches 75.3; 60.6; 59.9; 55.8 e 53.8%, respectively, in relation to the total stocked in the biomass.</p> |
