Atributos Químicos E Físicos De Solo Cultivado Com Oleráceas Em Microbacia Hidrográfica, Após Desastre Ambiental

Abstract: A matéria orgânica do solo é uma importante fonte primária de nutrientes às plantas e influencia a infiltração, retenção de água, suscetibilidade à erosão e agregação do solo. no entanto, esse processo está condicionado à qualidade e quantidade da matéria orgânica aportada. O objetivo deste trabalho foi avaliar a influência do desastre ambiental causado pela chuva em áreas de produção de oleráceas na região Serrana do Rio de Janeiro. Foram selecionadas as seguintes áreas: A1: sem impacto (testemunha); A2: sote… Show more

“…Area 1 (BO-F; 22°17'13.9'' and 42°39'56.8''S) is grown with black oat (Avena strigosa) as soil cover crop since late 2011. This area was totally buried in January 2011, due to overflows of water bodies, and remained flooded for 2 months with large depositions of sand (ROSSI et al, 2015). The black oat is killed with herbicide as in Area 1 in the upper section, but the sowing (broadcasting of seeds) was done without soil turning.…”

“…This study was conducted in a vegetable production area, namely the Rio Grande Farm, located in the Barracão dos Mendes watershed, in Nova Friburgo municiaplity, a mountainous region of Rio de Janeiro State, Brazil. The region is characterized by soils with low pedogenic development, such as Cambissolo Háplico -Inceptisol, associated with more developed soils, such as Argissolo Vermelho Amarelo -Ultisol (Rossi et al, 2015). The climate is humid subtropical (Cfa in the Köppen-Geiger climate classification system).…”

“…In January 2011, an environmental disaster triggered by heavy rainfall (182.8 mm in 2 h) resulted in the destruction of extensive areas in Nova Friburgo, a municipality located in the mountainous region of Rio de Janeiro State, Brazil. Landslides, mudflow, and river floods affected more than 60 % of the area planted with vegetable crops (Seapec RJ, 2011;Rossi et al, 2015). The same region experienced a less severe flood event in 2015.…”

“…A recuperação das áreas degradadas do Nordeste do Brasil, caracterizadas por erosão do solo e empobrecimento da fauna e da flora, demanda ações adequadas a condições ambientais muito deterioradas, particularmente no que se refere ao solo (Barreto et al, 2010;Brasileiro, 2009;Dias et al, 2014;Farias et al, 2013;Sousa et al, 2012;Rossi et al, 2015). Neste contexto, pode-se pensar na reconstrução de toda a camada superficial removida pela erosão, o que na prática é trabalhoso, demorado e caro, inviabilizando esta alternativa.…”
