Resumo: | Eucalyptus cultivation has increased in all Brazilian regions. In order to recommend good management practices it is necessary to understand differences in soil properties where eucalyptus is planted. In addition, aggregate stability analyses have proved to be a useful tool to measure soil effects caused by changes in management practices. Besides, the evaluation of soil erosion is an important tool for planning of conservationist management actions allowing appropriate changes on land-use and implementation of sustainable management strategies in the long-term. Thus, the objectives of this study were: i) to determine the main soil properties for different soil classes, and assess the relationship between aggregate stability and changes in soils under eucalyptus plantation, and ii) to predict the potential annual soil loss using the Universal Soil Loss Equation (USLE) coupled in a Geographical Information System (GIS). We studied representative soils within three eucalyptus cultivated regions. In the Espírito Santo state the soils selected were classified as dystrocohesive Yellow Argisol - PA1 (Hapludult), moderately rocky Yellow Argisol - PA2 (Hapludult), and dystrophic Haplic Plinthosol - FX (Phinthaquox). In the Rio Doce Valley, center-east region of Minas Gerais state, the samples were collected in dystrophic Red-Yellow Latosol - LVA (Haplustox) and dystrophic Red Latosol - LV (Haplustox). In the south region of Brazil the area encompasses eutrophic Red Argisol - PVe (Rhodudalf), dystrophic Red-Yellow Argisol - PVA (Hapludult), and dystrophic Haplic Cambisol - CXbd (Dystrudept). Physical, chemical, and mineralogical analyses were performed for the A horizon to characterize the predominant soil profiles. Aggregate stability was measured using the high-energy moisture characteristic (HEMC) technique. Aggregate stability ratio was greater than 50% for all soils. This fact shows for highly weathered soils with large amount of 1:1 clay minerals, that the aggregate stability index was high. In the Espírito Santo we performed the USLE model in order to evaluate soil erosion. All the USLE factors were generated in a distributed approach using GIS framework. Results showed that the average soil loss was 6.2 t ha-1 yr-1. Relative to soil loss tolerance, 86% of the area presented erosion rate smaller than the tolerable value. |

Para recomendar práticas de manejo adequadas é necessário o entendimento dos diferentes atributos do solo onde esta cultura está instalada. Além disso, a análise da estabilidade de agregados tem provado ser uma boa ferramenta para medir os efeitos causados no solo devido às mudanças nas práticas de manejo. Além disso, a avaliação do processo erosivo é um importante instrumento no planejamento do manejo conservacionista, permitindo realizar mudanças apropriadas no uso do solo e programar estratégias de manejo em longo prazo. Assim, os objetivos deste estudo foram: i) determinar os principais atributos do solo para as diferentes classes de solo e avaliar sua relação com a estabilidade de agregados em solos sob cultivo de eucalipto; e ii) estimar o potencial de perdas de solo anual através da Equação Universal de Perdas de Solo (EUPS) acoplada no Sistema de Informação Geográfica (SIG). Solos representativos de três regiões cultivadas com eucaliptos foram utilizados. No Espírito Santo os solos selecionados foram classificados como Argissolo Amarelo coesivo distrófico (PA1), Argissolo Amarelo moderadamente rochoso (PA2) e Plintossolo Háplico distrófico (FX). No Vale do Rio Doce, região centro-leste de Minas Gerais, as amostras foram coletadas em um Latossolo Vermelho Amarelo distrófico (LVA) e um Latossolo Vermelho distrófico (LV). Na região sul do Brasil a área abrange um Argissolo Vermelho eutrófico (PVe), um Argissolo Vermelho Amarelo distrófico (PVA) e um Cambissolo Háplico distrófico (CXbd). Análises físicas, químicas e mineralógicas foram realizadas nos horizontes A dos perfis de solo estudado. A estabilidade de agregados foi avaliada através da técnica high-energy moisture characteristic (HEMC). A estabilidade de agregados foi maior que 50% para todos os solos estudados. Este fato mostra que o índice de estabilidade de agregados foi elevado para solos altamente intemperizados com grandes quantidades de argilo-minerais 1:1. No Espírito Santo a avaliação do risco de erosão foi realizada por meio da EUPS. Os fatores da EUPS foram gerados de forma distribuídos utilizando a plataforma SIG. Os resultados mostraram uma perda de solo média de 6,2 t ha-1 ano-1. Em relação à tolerância de perdas de solo, 86% da área apresentaram taxas de erosão abaixo dos valores de tolerância de perdas.UNIVERSIDADE FEDERAL DE LAVRASDCS - Departamento de Ciência do SoloUFLABRASILNorton, Lloyd DarrellSilva, Marx Leandro NavesLima, Luiz AntônioOliveira, Geraldo César deCuri, NiltonAvanzi, Junior Cesar2014-09-17T01:15:32Z2014-09-17T01:15:32Z2014-09-162009-07-07info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisapplication/pdfAVANZI, J.
