Resumo: | The evaluation and monitoring of soil quality, in the micro-drainage basins which contribute directly to the Rio Descoberto reservoir, in the Rio Descoberto drainage basin, Distrito Federal (DF), Brazil, are necessary, due to its disordered rural occupation. Thus, this study aimed at evaluating the quality indicators of Red Latosol (RL), in micro-drainage basins located in the northern Rio Descoberto drainage basin, under diversified uses and managements: Savannah (SA), reforestation (RF), native pasture (NP), cultivated pasture (CP), agriculture with covered soil (AC) and agriculture with partial soil covering (AP). Soil density (SD) presented the lowest value for SA and the highest one for AP. The CP area showed the highest values for soil resistance to penetration, reflecting the effect of animal trampling. The highest value for organic matter (OM) was 55.5 g kg-1, in the CP, and the lowest one was observed in the AC (37.5 g kg-1), where decomposition processes are favored. The cation exchange capacity varied from 7.80 cmolc dm-3 (NP) to 9.75 cmolc dm-3 (RF), pointing out the liming effect. The values obtained for microbial biomass carbon and basal respiration showed positive effects of the grass root system in the development of microorganisms. Among the soil quality attributes evaluated, the OM and SD stood out, confirming that a more intensive agricultural activity is directly related to the quality reduction of the RL evaluated. |

Assim, este trabalho objetivou avaliar indicadores de qualidade de Latossolo Vermelho (LV), em microbacias da parte norte da Bacia do Rio Descoberto, com usos e manejos diversificados: Cerrado (CE), reflorestamento (RF), pastagem nativa (PN), pastagem plantada (PP), agricultura com solo coberto (AC) e agricultura com cobertura parcial do solo (AP). A densidade do solo (DS) apresentou o menor valor para CE e o maior para AP. A área de PP foi a que apresentou os maiores valores de resistência do solo à penetração, refletindo o efeito do pisoteio de animais. O maior valor para a matéria orgânica (MO) foi de 55,5 g kg-1, na PP, e o menor valor foi observado na AC (37,5 g kg-1), ambiente onde processos de decomposição são favorecidos. A capacidade de troca catiônica variou de 7,80 cmolc dm-3 (PN) a 9,75 cmolc dm-3 (RF), mostrando o efeito da calagem. Os valores obtidos para o carbono da biomassa microbiana e respiração basal indicaram efeitos positivos do sistema radicular das gramíneas, no desenvolvimento de micro-organismos. Dentre os atributos de qualidade do solo avaliados, destacaram-se a MO e a DS, que permitiram constatar que o uso agropecuário mais intensivo está diretamente relacionado à redução na qualidade do LV estudado.Escola de Agronomia - Universidade Federal de Goiás2012-12-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa com amostragem aleatóriaapplication/pdfhttps://revistas.ufg.br/pat/article/view/16229Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 42, n. 4, Oct./Dec. 2012; 446-454Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 42, n. 4, out./dez. 2012; 446-454Pesquisa Agropecuária Tropical; v. 42, n. 4, out./dez. 2012; 446-4541983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/pat/article/view/16229/12741Copyright (c) 2020 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessChaves, Aurélio Alves AmaralLacerda, Marilusa Pinto CoelhoGoedert, Wenceslau J.Ramos, Maria Lucrécia GerosaKato, Eiyti2020-07-10T11:42:07Zoai:ojs.revistas.ufg.br:article/16229Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:55:53.734891Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true |
