description The increase of Greenhouse Gases (GHG) emissions derived from human activities are considered the main cause of current climate change and the livestock sector is responsible for 18 % of the GHG emissions in CO2 equivalent. Kikuyu grass can optimize both carbon capture and carbon fixation. The aim of this paper was to identify carbon stocks in the kikuyu grass in its different compartments, above-ground biomass (AB) and below-ground biomass (BB) at 20 and 40 cm soil depth, under the traditional and silvopastoral systems in different reliefs. Six successive samplings (M) were taken according to the grazing system (traditional and silvopastoral system), and the geoform of the terrain (concave flank (CCF), convex flank (CXF), rectilinear flank (RF) and flat relief (FR)). The above-ground biomass and below-ground biomass were sampled. The statistical method used was a design in incomplete randomized blocks, two treatments were evaluated (T) (T1: traditional system and T2: silvopastoral system) with four blocks (B) in each one (B1: CCF, B2: CXF, B3: RF, B4: FR). This experiment was done from June 2016 to June 2017 in San Pedro de los Milagros, Antioquia, Colombia. The results allowed to determine that the roots at 20 cm depth, the dead creeping stems, and the leaves were the compartments with the highest carbon stocks (4.52, 3.58 and 1.9 ton of C ha-1, respectively). Differences were found (P < 0.05) between flat and rectilinear relief for the biomass of leaves, and between the flat relief with the other reliefs evaluated for the variable thick roots at 20 cm depth. The biomass produced by the plant is directly proportional to the incorporated carbon. The root biomass, both fine and thick roots, contributes to capture on average 2 820 kg and 655 kg of carbon per hectare at of 20 and 40 cm depth respectively. Kikuyu grass contributes to keep carbon reserves in the grasslands. Due to the high production of below-ground biomass and creeping stems, and its high capacity of regrowth under adverse conditions, this grass plays an important role in the reduction of GHG and the conservation of high tropical soils under specialized dairy systems.

El pasto kikuyo puede optimizar tanto la captura como la fijación del carbono. El objetivo del trabajo fue identificar las existencias de carbono en el pasto kikuyo en sus diferentes compartimentos, biomasa aérea (BA) y biomasa radicular (BR), a 20 y 40 cm de profundidad del suelo, bajo los sistemas tradicional y silvopastoril en diferentes relieves. Se realizaron seis muestreos (M) sucesivos de acuerdo al sistema de pastoreo (tradicional y silvopastoril), la geoforma del terreno (flanco cóncavo (FCC), flanco convexo (FCX), flanco rectilíneo (FR) y relieve plano (RP)). Se muestrearon la biomasa aérea (BA) y de raíces (BR). El método estadístico utilizado fue un diseño en bloques incompletos aleatorizados, se evaluaron dos tratamientos (T) (T1: tradicional y T2: silvopastoril) con cuatro bloques (B) en cada uno (B1: FCC, B2: FCX, B3: FR, B4: RP). El trabajo se realizó entre junio 2016 y junio 2017 en San Pedro de los Milagros, Antioquia Colombia. Los resultados permitieron determinar que las raíces a 20 cm de profundidad, el colchón muerto y las hojas, fueron los compartimentos con mayores existencias de carbono (4.52, 3.58 y 1.9 ton de C ha-1 respectivamente). Se encontraron diferencias (P < 0.05) entre relieve plano y el relieve rectilíneo para la biomasa de hojas, y entre el relieve plano con los demás relieves evaluados para la variable raíces gruesas a 20 cm de profundidad. La biomasa producida por la planta es directamente proporcional al carbono incorporado. La biomasa radicular, tanto para raíces finas como gruesas, contribuye a capturar en promedio 2 820 y 655 kg ha-1 de carbono a 20 y 40 cm de profundidad respectivamente. El pasto kikuyo contribuye a mantener reservas de carbono en las praderas. Por la alta producción de biomasa radicular, de colchón y la alta capacidad de rebrote en condiciones adversas, se concluye que este pasto juega un papel importante en la disminución de GEI y la conservación de los suelos del trópico alto bajo sistemas de lechería especializada.Universidad de Costa Rica2019-09-01info:eu-repo/semantics/publishedVersionArticleartículo originalhttp://purl.org/coar/resource_type/c_2df8fbb1info:eu-repo/semantics/articleapplication/pdftext/htmlhttps://revistas.ucr.ac.cr/index.php/rbt/article/view/3452910.15517/rbt.v67i4.34529Revista de Biología Tropical; Vol. 67 No. 4 (2019): Volume 67 – Regular number 4 – September 2019; 769–783Revista de Biología Tropical; Vol. 67 Núm. 4 (2019): Volumen 67 – Número regular 4 – Setiembre 2019; 769–783Revista Biología Tropical; Vol. 67 N.º 4 (2019): Volumen 67 – Número regular 4 – Setiembre 2019; 769–7832215-20750034-774410.15517/rbt.v67i4reponame:Portal de Revistas UCRinstname:Universidad de Costa Ricainstacron:UCRenghttps://revistas.ucr.ac.cr/index.php/rbt/article/view/34529/39634https://revistas.ucr.ac.cr/index.php/rbt/article/view/34529/39635Derechos de autor 2019 Maria Fernanda Medina, Maritza Pérez, Maria Fernanda Medina, Alejandro Hurtado, Elkin Mauricio Arboleda, Marisol Medinahttp://creativecommons.org/licenses/by/4.0acceso abiertohttp://purl.org/coar/access_right/c_abf2info:eu-repo/semantics/openAccess2022-06-13T14:26:54Zoai:portal.ucr.ac.cr:article/34529Portal de revistashttps://revistas.ucr.ac.cr/Universidadhttp://www.ucr.ac.crhttps://revistas.ucr.ac.cr/index.php/index/oaijorge.polanco@ucr.ac.crCosta RicaNo aplicaNo aplicaNo aplicaopendoar:2025-08-13T10:24:42.229Portal de Revistas UCR - Universidad de Costa Ricafalse
