| description |
The objective of this study was to evaluate the soil total nitrogen (TN), and N contents in humic substances (HS) of the organic matter in aggregates of soils cultivated with onion under no-till system for horticulture (NTSH) and conventional tillage system (CTS), comparing with an area of forest. The evaluated treatments were natural vegetation (control), 100% black oats, 100% rye, 100% oilseed radish, intercrop of oilseed (14%) + rye (86%), intercrop of oilseed (14%) + black oats (86%), area under CTS of onion for ±37 years, and area with secondary forest for ±30 years. Five years after the NTSH implementation, undisturbed soil samples from the layers 0-5 cm, 5-10 cm, and 10-20 cm were collected; these samples presented aggregate sizes between 2.0 mm and 8.00 mm. The TN, and N contents of the HS were subdivided into fulvic acids (N-FA), humic acids (N-HA), and humin (N-HU) fractions. The change from CTS to NTSH increases the TN and N-HU contents in the 0-5 cm soil layer. The intercrop of oats and oilseed radish, used as soil plant cover species in NTSH, presented a greater increase in N-HU (0-20 cm) than the other treatments. Black oats, and natural vegetation presented a greater increased in N-HA, and N-FA contents, respectively, in the 10-20 cm layer, than the other treatments in NTSH and CTS. CTS with millet as soil plant cover presented a greater increase in N-FA (0-20 cm) contents than the NTSH treatments. |

Los tratamientos evaluados fueron: vegetación espontánea; 100% avena; 100% centeno; 100% nabo; cultivos asociados de nabo (14%) + centeno (86%); cultivos asociados de nabo (14%) + avena (86%); área bajo SPC de cebolla (±37 años) y de bosque secundario de ±30 años). Cinco años después de la implantación del SDH fueran recogidas muestras no disturbados del suelo en las capas 0-5, 5-10 y 10-20 cm y obtenidos los agregados (entre 2,0 y 8,00 mm). En estos se determinaron los niveles de NT y el N de las SH, subdivididos en fracción ácidos fúlvicos (N-FAF), ácidos húmicos (N-FAH) y humina (N-HUM). La conversión de áreas de SPC a SDH favorece el aumento de los niveles de NT y N-HUM en la capa de 0-5 cm. Entre las especies de plantas de cobertura utilizadas en el SDH, los cultivos asociados de avena + nabo favorecieron el aumento del N-HUM (0-20 cm) en comparación a los demás tratamientos. La avena solo y el control con vegetación espontánea aumentaron los niveles de N-FAH y N-FAF, respectivamente, en la capa de 10-20 cm, en comparación a los demás tratamientos en SDH y SPC. El SPC con mijo como planta de cobertura aumentó los niveles de N-FAF (0-20 cm) en comparación con el SDH.application/pdfengengSociedad Colombiana de Ciencias Hortícolas-SCCH and Universidad Pedagógica y Tecnológica de Colombia-UPTChttps://revistas.uptc.edu.co/index.php/ciencias_horticolas/article/view/7339/pdfhttps://creativecommons.org/licenses/by-nc/4.0/http://purl.org/coar/access_right/c_abf682http://purl.org/coar/access_right/c_abf2Revista Colombiana de Ciencias Hortícolas; Vol. 12 No. 1 (2018); 166-174Revista Colombiana de Ciencias Hortícolas; Vol. 12 Núm. 1 (2018); 166-174Revista Colombiana de Ciencias Hortícolas; Vol. 12 No 1 (2018); 166-174Revista Colombiana de Ciencias Hortícolas; V. 12 N. 1 (2018); 166-174Revista Colombiana de Ciencias Hortícolas; v. 12 n. 1 (2018); 166-1742422-37192011-2173Allium cepa L.cover plantsaggregationhumic acidssoil nitrogentillage system.SB320-353.5S622-627Allium cepa L.plantas de coberturaagregaciónácidos húmicosnitrógeno del suelosistemas de labranza.SB320-353.5S622-627Total nitrogen and humic substances in aggregates of soils with onion crops under no-tillage and conventional tillage systemsNitrógeno total y sustancias húmicas en agregados del suelo cultivado con cebolla bajo siembra directa y preparación convencionalExperimentalExperimentalinfo:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_7181http://purl.org/coar/resource_type/c_2df8fbb1info:eu-repo/semantics/publishedVersionhttp://purl.org/coar/version/c_970fb48d4fbd8a765http://purl.org/coar/version/c_970fb48d4fbd8a85Santos, Luiz Henrique dosLoss, ArcângeloLourenzi, Cledimar RogérioSouza, MoniqueGonzatto, RogérioKurtz, ClaudineiBrunetto, GustavoComin, Jucinei José001/16780oai:repositorio.uptc.edu.co:001/167802025-07-18 11:49:44.221https://creativecommons.org/licenses/by-nc/4.0/metadata.onlyhttps://repositorio.uptc.edu.coRepositorio Institucional UPTCrepositorio.uptc@uptc.edu.co |
