It publishes scientific articles, systematic literature reviews and technical notes, in Portuguese, Engilsh and Spanish languages, an on ecology and forest nutrition, with emphasis on the studies of biomass inventories, forest species nutrition, nutrient and carbon cycling, ecology of natural and implanted ecosystems, among other topics.</p> <p><strong>eISSN 2316-980X | Qualis/CAPES (2017-2020) = B4</strong></p>https://periodicos.ufsm.br/enflo/article/view/84367Root density of Megathyrsus maximus BRS Quênia and Urochloa brizantha BRS Piatã in silvipastorl systems2024-06-07T08:47:48-03:00Hérica André da Silvahericasilva_20@hotmail.comAmanda Prudente Velozovelozo_a@hotmail.comPaulo Vitor Divino Xavier de Freitaspaulovitor_freitas@hotmail.comAbílio Rodrigues Pachecoabilio.pacheco@embrapa.brFrancine Neves Calilfncalil@gmail.comCarlos de Melo e Silva-Netocarloskoa@gmail.com<p>The objective of this study is to determine the root density of <em>Megathyrsus maximus</em> and <em>Urochloa brizantha</em> forages at a depth of 20 cm alone, in relation to their distances from the tree component in two systems of livestock-forest integration with two entities. For this study, the following livestock-forest integration systems were carried out: a system with 3 years of composting by AEC-043 eucalypts clones spaced in strips of simple lines of 15x2 m and the forage component <em>Megathyrsus maximus</em> cv. Quenia; The other system requires 2 years of growth and AEC-2034 eucalyptus clones with the same forest root and forage component <em>Urochloa brizantha</em> BRS Piatã. Five transects were collected randomly in each of two livestock-forest integration systems and measured 5 distances from the tree component for root collection in the dry period. The roots are separated and dried only for density evaluation. In the area as a livestock-forest integration system with 2 years of life with eucalypts clones AEC-2043 and <em>Urochloa brizantha</em> forage, a higher average production of total density of roots at a distance of 5 meters from the tree component, with value of 11.75 g and less root density at zero distance with 8.63 g. In the 3-year livestock-forest integration system, with AEC-043 eucalyptus clones and Megathyrsus maximus forage component, the highest concentration of root density occurred at distance zero with 10.23 g and lowest root density at distance 5 m with 4.45 g. In both systems, eucalyptus influenced the root system of the forage grass.</p>2024-06-03T00:00:00-03:00Copyright (c) 2024 Revista Ecologia e Nutrição Florestal - ENFLO
