“…It is probable that the higher root volume improved soil structure due to the highest tree density in Paricá III. Assis et al (2015) also reported greater changes in soil density and pore distribution in the layer of 0.10-0.20 m, in integrated systems.…”

“…Plant production characteristics (Paciullo et al, 2011) and soil physical quality are also affected by tree shading (Souza Neto et al, 2014;Assis et al, 2015). However, there are few studies on the changes in soil attributes under forest arrangements depending on tree line distances (Souza Neto et al, 2014;Assis et al, 2015).…”

The objective of this work was to compare the structural quality and water retention curve of a Haplustox under single, double, and triple "paricá" (Ochroma pyramidale) lines in an integrated production system at 50 months of implantation. Soil was collected from five sampling points considering the distances from the tree lines. Undisturbed samples were collected from the 0.00-0.10 and 0.10-0.20-m layers in order to assess porosity, density, soil penetration resistance, soil water retention curve, and the "S" index. The forest arrangement based on three paricá lines promoted better soil physical conditions than the system using single lines. The main changes were recorded in the 0.10-0.20-m layer, with increased microporosity and decreased cryptoporosity and resistance to penetration. The arrangements using single and double paricá lines result in higher volume of available water and greater soil compaction.Index terms: Ochroma pyramidale, ICLF, physical quality of the soil, retention curve, water in the soil. Atributos físico-hídricos do solo em sistema integrado de produção com diferentes arranjos do componente florestal paricáResumo -O objetivo deste trabalho foi comparar a qualidade estrutural e a curva de retenção de água de um Latossolo Vermelho-Amarelo sob arranjos de linhas simples, duplas e triplas de paricá (Ochroma pyramidale), em um sistema integrado de produção com 50 meses de implantação. O solo foi coletado em cinco pontos de amostragem em relação à distância do renque das árvores. Foram coletadas amostras indeformadas nas camadas de 0,00-0,10 e 0,10-0,20 m para avaliar porosidade, densidade, resistência do solo à penetração, curva de retenção de água no solo e índice "S". O arranjo florestal com três linhas de paricá promoveu melhores condições físicas ao solo em comparação ao renque de linha simples. As principais alterações ocorreram na camada de 0,10-0,20 m, com aumento da microporosidade e diminuição da criptoporosidade e da resistência à penetração. Os arranjos com paricá em linhas simples e dupla resultam em maiores volumes de água indisponíveis e compactação ao solo.Termos para indexação: Ochroma pyramidale, ILPF, qualidade física do solo, curva de retenção, água do solo.

“…For example, Assis et al (2015) aimed to determine the alterations in the physical features of the 0-0.10-and 0.10-0.20-m layers of Cerrado soil under iCLW, that is, iLPF1 and iLPF3, respectively; the results allowed the authors to conclude that the iCLW systems enhanced the physical quality of the soil relative to degraded pasture. Patterns of density and porosity in the 0.10-0.20-m soil layer were mainly responsible for discriminating the integrated systems from degraded pasture.…”

The physical properties of a soil can be influenced by management systems, but information on the effects of management systems such as integrated crop-livestock-woods is still incipient and inconclusive. Therefore, this study aimed to evaluate the changes in the physical attributes of Cerrado soil under different management systems. Soil samples were collected and subjected to an experiment with a completely randomized, 5 x 3 factorial design with five replications. The treatments were different management systems (notillage, integrated livestock-woods, cultivated pasture, degraded pasture and preserved area -reference), and samples were collected from three soil depths (0-10, 10-20 and 20-30 cm). The following physical soil characteristics were evaluated: density, total porosity and resistance to penetration. Additionally, the organic matter content has previously been determined for the different systems under analysis. The results showed that soils under conservation management involving corn and integrated crop-livestock-woods presented greater soil density but were also less susceptible to compaction, especially the superficial soil layer. The resistance of the soil profile to penetration was lower under conservation management compared to pasture (cultivated or degraded), but it was superior to that of the reference soil. The areas under braquiária ruziziensis pasture or degraded with Urochloa decumbens pasture presented higher resistance to soil penetration.

“…Although soil conservation was not considered a priority in government agendas in the past (Guerra et al, 2014), many agricultural production systems focusing on soil conservation have been developed and are being used in Brazil over recent decades. In commodity producing regions, some management systems have been rising in importance, such as no-tillage system (NTS), crop-livestock integrated system (CLIS) and croplivestock-forest integrated system (CLFIS) (Muniz et al, 2011;Assis et al, 2015), while in other regions, family farmers are also experiencing new integrated systems, such as organic farming and agroforestry (Martinelli et al, 2010). Evaluating the impact of these technologies on soil ES is required to subsidize decision-making and international agreements.…”

-Human pressure on ecosystems has undesirable impacts on human well-being. After the Millennium Project, much interdisciplinary research has been developed worldwide aiming to understand these impacts on ecosystem flows and processes, and to learn about the costs and the benefits of ecosystem services for production. Soil provides many ecosystem services, since its multi-functionality is the basis for food production, water filtration, nutrient cycling, and other goods essential to life. This article presents the main concepts and classifications of soil ecosystem services and of its functions; the indicators and the methods for assessment, modeling, and valuation of ecosystem services; some recent applications to assess and evaluate impacts of agricultural management practices on soil ecosystem services; as well as challenges and opportunities for research and for development of public policies related to agro-environmental sustainability in Brazil. Although the role of soil in supplying ecosystem services is yet undervalued, scientists are gradually recognizing soil processes and functions as fundamental to assess ecosystem services and the effects of land use and management on them. Interdisciplinary approaches to integrate science and public policies are necessary to build governance based on ecosystem services.Index terms: economic valuation, environmental services, soil function, soil indicators, soil management, public policy, soil quality. Panorama atual e potencial de aplicação da abordagem dos serviços ecossistêmicos do solo no BrasilResumo -A pressão humana sobre os serviços ecossistêmicos tem resultado em impactos indesejáveis sobre o bem-estar humano. Com o Projeto Millennium, várias pesquisas interdisciplinares têm sido desenvolvidas em todo o mundo com o objetivo de entender esses impactos sobre os fluxos e os processos dos ecossistemas e internalizar os custos e os benefícios dos serviços ecossistêmicos para a produção. O solo fornece muitos serviços ecossistêmicos, uma vez que sua multifuncionalidade é a base para a produção de alimentos, filtração de água, ciclagem de nutrientes e outros bens essenciais à vida. Este artigo apresenta os principais conceitos e classificações dos serviços ecossistêmicos do solo e de suas funções; os indicadores e os métodos de avaliação, modelagem e valoração dos serviços ecossistêmicos; algumas aplicações recentes para avaliar impactos de práticas de manejo agrícola sobre os serviços ecossistêmicos do solo; bem como os desafios e as oportunidades para a pesquisa e para o desenvolvimento de políticas públicas relacionadas à sustentabilidade agroambiental no Brasil. Apesar de o papel do solo para prestação de serviços ecossistêmicos ainda ser subestimado, os cientistas têm gradualmente reconhecido os processos e as funções do solo como fundamentais para avaliar os serviços ecossistêmicos e os efeitos do uso e manejo da terra sobre eles. Abordagens interdisciplinares que integrem ciência e políticas públicas são necessárias para construir uma governança com...
