The interception of the rainfall by the forest canopy has great relevance to the nutrient geochemistry cycle in low fertility tropical soils under native or cultivated forests. However, little is known about the modification of the rainfall water quality and hydrological balance after interception by the canopies of eucalyptus under pure and mixed plantations with leguminous species, in Brazil. Samples of rainfall (RF), throughfall (TF) and stemflow (SF) were collected and analyzed in pure plantations of mangium (nitrogen fixing tree -NFT), guachapele (NFT) and eucalyptus (non-nitrogen fixing tree -NNFT) and in a mixed stand of guachapele and eucalyptus in Seropédica, State of Rio de Janeiro, Brazil. Nine stemflow collectors (in selected trees) and nine pluviometers were randomly disposed under each stand and three pluviometers were used to measure the incident rainfall during 5.5 months. Mangium conveyed 33.4% of the total rainfall for its stem. An estimative based on corrections for the average annual precipitation (1213 mm) indicated that the rainfall's contribution to the nutrient input (kg ha-1) was about 8.42; 0.95; 19.04; 6.74; 4.72 and 8.71 kg ha-1 of N-NH4+, P, K+, Ca+2, Mg+2 and Na+, respectively. Throughfall provided the largest contributions compared to the stemflow nutrient input. The largest inputs of N-NH4+ (15.03 kg ha-1) and K+ (179.43 kg ha-1) were observed under the guachapele crown. Large amounts of Na+ denote a high influence of the sea. Mangium was the most adapted species to water competitiveness. Comparatively to pure stand of eucalyptus, the mixed plantation intensifies the N, Ca and Mg leaching by the canopy, while the inputs of K and P were lower under these plantations.

Brachiaria Decumbens

O objetivo deste trabalho foi avaliar características morfofisiológicas e o valor nutritivo da Brachiaria decumbens, nas épocas chuvosas de 2003 e 2004, em um sistema silvipastoril, com faixas de 30 m de largura com essa gramínea, alternadas com faixas de 10 m com árvores de Acacia mangium, A. angustissima, Mimosa artemisiana, Leucaena leucocephala x L. diversifolia, Eucalyptus grandis. Foi adotado o delineamento de blocos ao acaso, em parcelas subsubdivididas (características morfofisiológicas) ou parcelas subdivididas (características do valor nutritivo), com quatro repetições. Em 2003, o sombreamento foi de 65% da radiação incidente fora do bosque e, em 2004, de 35%, depois da retirada de árvores de eucalipto. Sob sombreamento, a densidade de perfilhos, o índice de área foliar e a massa de forragem foram maiores no segundo ano. Os teores médios de fibra em detergente neutro (FDN) foram maiores a pleno sol que sob sombreamento, enquanto os valores médios de proteína bruta (PB) e a digestibilidade in vitro da matéria seca foram maiores à sombra. O sombreamento moderado aumenta os teores de PB, reduz os teores de FDN e incrementa a digestibilidade da forragem de gramíneas que crescem sob a copa das árvores.
