| Aggregation can suffer permanent or temporary changes to cyclical variations induced by management practices for soil and plant growth. The study evaluated the temporal and spatial variation of the stability of water stable aggregates and its relationship with the organic matter content in an Hapludalf in Santa Maria municipality, Rio Grande do Sul State, Brazil. The treatments were four tillage systems for deployment of Eucalyptus grandis: no-tillage, chisel, chisel tillage plus harrowing and rotary tiller. Soil samples were collected in the layer of 0.00 to 0.05 m for determination of the density, and stability in water of stable organic matter aggregates contents of the soil. Chisel, chisel tillage plus harrowing and rotary tiller resulted in lower... |

| Abstract The objective of this work was to present an approach to evaluate soil functions in agroecosystems and their impact on environmental services (ES). An approach with case studies was proposed to assess the relationship between the establishment and management of agroecosystems, in three Brazilian biomes (Atlantic Forest, Cerrado, and Caatinga), and their environmental services provision, considering the specificities of each area. A set of soil parameters that can be used as indicators to monitor changes in the agroecosystem was also proposed. The environmental services types most affected by the establishment and management of the agroecosystems were the supporting and provisioning services, showing the potential of agricultural management in... |

| Soil acidity and low natural fertility are the main limiting factors for grain production in tropical regionssuch as the Brazilian Cerrado. The application of lime to the surface of no-till soil can improve plant nutrition, dry matter production, crop yields and revenue. The present study, conducted at the Lageado Experimental Farm in Botucatu, State of São Paulo, Brazil, is part of an ongoing research project initi-ated in 2002 to evaluate the long-term effects of the surface application of lime on the soil?s chemical attributes, nutrition and kernel/grain yield of peanut (Arachis hypogaea), white oat (Avena sativa L.) and maize (Zea mays L.) inter cropped with palisade grass (Urochloa brizantha cv. Marandu), as well as the forage dry matter yield of... |

| Este trabalho, executado pela Divisão de Pesquisa Pedológica do Ministério da Agricultura para o Grupo GTPLAN/PROTERRA DO INCRA, teve por base o Levantamento de Reconhecimento dos Solos das áreas prioritárias indicadas, realizado pela DPP em 1972 visando a um melhor aproveitamento agrícola dos solos para fins de colonização, apresentado sob a forma de um relatório condensado com (2) dois mapas de Aptidão Agrícola dos diferentes solos, para cada área, segundo (2) dois Sistemas de Manejo: primitivo e desenvolvido - sem irrigação. Foram consideradas para cada Sistema de Manejo, culturas de ciclo curto e de ciclo longo. |

| O Levantamento de Reconhecimento dos Solos do Oeste do Estado do Paraná, que constitui a base do presente trabalho, foi realizado pela Divisão de Pesquisa Pedológica (atual SNLCS da EMBRAPA) - em convênio com o Comissão de Estudo dos Recursos Naturais Renováveis do Estado do Paraná - Projeto de Recursos do Solo (CERENA), com o apoio financeiro do Instituto Brasileiro do Café (IBC) e do Conselho de Cooperação Técnica da Aliança paro o Progresso (CONTAP). Em geral as informações contidas nos levantamentos pedológicos, não são de fácil compreensão para a maioria dos não especialistas em solos, de modo que para torná-los mais acessíveis são indispensáveis as interpretações desses mapas. O propósito do trabalho em vista é o de por ao alcance do maior número... |

| In Brazil, grazing mismanagement may lead to soil and pasture degradation. To impede this process, integrated cropping systems such as silvopasture have been an effective alternative, allied with precision agriculture based on soil mapping for site-specific management. In this study, we aimed to define the soil property that best sheds light on the variability of eucalyptus and forage yield. The experiment was conducted in the 2011/12 crop year in Ribas do Rio Pardo, Mato Grosso do Sul State, Brazil. We analyzed linear and spatial correlations between eucalyptus traits and physical properties of a Typic Quartzipsamment at two depths (0.00-0.10 and 0.10-0.20 m). For that purpose, we set up a geostatistical grid for collection at 72 points. Gravimetric... |
