Using herbaceous legumes in agricultural systems yields great quantities of plant residues, allowing changes in soil organic matter quality and content over the years. This study was conducted on an Ultisol, at Seropédica, RJ, Brazil, to evaluate the effects of different perennial herbaceous legumes on soil organic matter quality. A factorial scheme with three replications was used to evaluate the species: forage groundnut cv. BR-14951 (Arachis pintoi), tropical kudzu (Pueraria phaseoloides), and siratro (Macroptillum atropurpureum). After the first cut, each plot was divided into two subplots; plants were cut and left on the soil surface or cut and removed. Soil samples of a closed area covered by spontaneous vegetation (mainly C3 plants) or by Panicum maximum were also analyzed. Samples were collected from two layers (0-5 and 5-10 cm.), processed for the fractionation of organic matter and the evaluation of structural characteristics of humic acids (HA). Evaluated legumes did not change total organic carbon content, but promoted HA accumulation in the superficial soil layer. Humic acids may be used as indicators of the management effects on soil organic fractions, because there was significant incorporation of carbon and nitrogen derived from the legume residues, even for the short experimentation time (28 months). Residue management did not modify quantitative aspects of the distribution of the humified organic matter, but promoted, however, a higher condesation degree of humic acids evaluated by the elementary composition, IR and fluorescence spectroscopy. O uso de leguminosas herbáceas em sistemas agrícolas permite o aporte de quantidades expressivas de fitomassa, possibilitando alterações no teor e na qualidade da matéria orgânica do solo ao longo dos anos. Este trabalho avalia a quantidade de matéria orgânica de um Argissolo Vermelho Amarelo localizado em Seropédica, RJ, e cultivado com diferentes espécies de leguminosas herbáceas perenes: amendoim forrageiro cv. BR-14951 (Arachis pintoi), cudzu tropical (Pueraria phaseoloides) e siratro (Macroptillum atropurpureum), num delineamento fatorial com três repetições, considerando a manutenção da parte aérea depois do corte na parcela ou a retirada da parte aérea da área experimental. Foram também analisadas amostras de uma área adjacente com vegetação espontânea (mata de capoeira) e capim colonião (Panicum maximum). As amostras de solo foram coletadas em duas profundidades (0-5 e 5-10 cm), realizando-se o fracionamento da matéria orgânica e a avaliação das características estruturais dos ácidos húmicos. As leguminosas avaliadas não alteram o conteúdo de carbono orgânico total, mas promoveram acúmulo de ácidos húmicos (AH) na camada superficial. Os AH podem ser utilizados como compostos indicadores dos efeitos do manejo sobre a fração orgânica do solo, pois apesar do pouco tempo de implementação do experimento (28 meses) foi verificada incorporação significativa de carbono e nitrogênio provenientes dos resíduos orgânicos das leguminosas. O manejo dos resíduos vegetais não alterou aspectos quantitativos da distribuição de matéria orgânica humificada, mas conferiu maior grau de condensação aos ácidos húmicos avaliados pela análise da composição elementar, espectroscopia de IV e de fluorescência.

The practice of grafting in the global viticulture began from the late nineteenth century, when the accidental introduction and infection of European vineyards bya natural insect from the Mississippi region in the United States. knownas phylloxera (Daktulosphaira vitifolil), which forced the use of American resistant wild species (Vitis ripens, vitis rupestris, etc.) as rootstocks. Therefore, resistance to phylloxera was the primary criterion for selection of rootstocks for grapevine. Soon after planting the first rootstocks, other problems arose, such as ferric chlorosis induced by excess of calcium present in many calcareous soils of Europe. This led to new breeding programs researches, especially in Europe. aiming to produce chlorosis resistant rootstocks, which was achieved by performing crosses with American species resistant to chlorosis, as Vitis berlandieri. Thus, wild species of American vines formed the genetic basis of most rootstocks used today worldwide. Those rootstocks developed were adapted to specific soil conditions and aimed to solve the existing problems in each viticulture region. Reynolds and Wardle (2001) outlined seven rnain criteria for choosing rootstocks in order of ímportance as phylloxera resistance, nematode resistance, adaptability to high pH soils, adaptability to saline soils, adaptability to soils with low pH, adaptability to waterlogged or poorly drained soils and adaptability to drought. Numerous studies have also shown that rootstocks affect agronomic and physiological characteristics of vines such as vigor, yield, size of bunches and berries, allocationof assimilates, sugar content and acidity of fruits and other important attributes of quality of grapes and wines. However, lhe choice of rootstock depends on the soil and environmental conditions of each region and within a region may undergo many varíations, which makes this is a difficult choice and local research work must be carried out for each growing grape region. In Brazil, research results were obtained in different grape cultivars and growing regions within the country. In general, tropical rootstocks developed by Instituto Agronômico de Campinas Breeding Programme, in São Paulo State named IAC 313 'Tropical', IAC 572 'Jales' and IAC 766 'Campinas' have shown good performance and vigor when grafted in different cultivars. In São Francisco Valley, nematode tolerant rootstocks and moderate vigor such as 'Harmony', 'S04' and 'Paulsen 1103' resulted in better balance between vegetative and reproductive growth and bunches with higher weight, better coloring and general appearance for 'Crimson Seedless', 'Sugraone' and 'Thompson Seedless' table grapes (Leão; Borges, 2011; Leão et aI.; 2011; Leão et ai., 2010). New studies have been performed to evaluate rootstocks for new table grape cultivars BRS Vitoria, BRS lsls and BRS Nubia recently released by Embrapa. In conclusion, the rootstocks use ín tropical viticulture has shown a great importance as a way to prevent soil diseases and pests and to control abiotic stresses, although the responses are specífic for each grape cultivar and environment.
