Impacts of reforestation on soil and soil organic carbon losses
Lense,Guilherme Henrique Expedito; Parreiras,Taya Cristo; Servidoni,Lucas Emanuel; Mincato,Ronaldo LuizABSTRACT Water erosion is a serious environmental problem that causes soil degradation, compromises its fertility and causes soil organic carbon (SOC) losses. Reforestation, encouraged by Brazilian environmental legislation, is a way to reduce water erosion. However, in tropical and subtropical regions, there is little information on the impact of reforestation on soil loss rates and SOC. Therefore, this study ...
Soil losses in the State of Rondônia, Brazil
Lense,Guilherme Henrique Expedito; Parreiras,Taya Cristo; Spalevic,Velibor; Avanzi,Junior Cesar; Mincato,Ronaldo LuizABSTRACT: In the state of Rondônia, deforestation, and inadequate soil use and management have intensified the water erosion process, causing degradation of agricultural land. Modeling is a tool that can assist in the adoption of targeted and effective measures for soil and water conservation in the region. In this context, the objective of the research was to model soil losses due to water erosion in the state...
Dinâmica espaço-temporal do uso e ocupação da terra no Município de Ribeirão Pr...
Ayer,Joaquim Ernesto Bernardes; Lämmle,Luca; Garofalo,Danilo Francisco Trovo; Mincato,Ronaldo Luiz; Servidoni,Lucas Emanuel; Pereira,Sueli YoshinagaRESUMO O ordenamento territorial na Região Sudeste do Brasil foi marcado por ciclos econômicos marcantes de uso e ocupação da terra. Para avaliar tal dinâmica foram realizados levantamentos de dados históricos e naturais do Município de Ribeirão Preto - SP. Neste contexto, foi adotado o método de análise espaço-temporal, baseado no mapeamento do uso e ocupação da terra, a partir da reconstituição do mapa de do ...
Modeling of soil organic carbon loss by water erosion on a tropical watershed
Lense,Guilherme Henrique Expedito; Moreira,Rodrigo Santos; Parreiras,Taya Cristo; Avanzi,Junior Cesar; Mincato,Ronaldo LuizABSTRACT Water erosion under tropical climate conditions is one of the main processes that change the balance between the inputs and outputs of soil organic carbon (SOC). Water erosion modeling using the Erosion Potential Method (EPM) can be used as an alternative to assist in understand soil carbon dynamics and its interaction with the erosive process. In this context, the objective of the study was to estimat...
Water erosion modeling by the Erosion Potential Method and the Revised Universa...
Lense,Guilherme Henrique Expedito; Moreira,Rodrigo Santos; Parreiras,Taya Cristo; Santana,Derielsen Brandão; Bolelli,Talyson de MeloAbstract Water erosion is the principal degradation process of tropical soils, and its effects can be measured by modeling techniques. Erosion models provide a diagnosis of the soil loss intensity and can support the planning of soil conservation practices. Models with low data requirements, such as the Revised Universal Soil Loss Equation (RUSLE) and, more recently, the Erosion Potential Method (EPM), are main...
Adaptation and application of the erosion potential method for tropical soils1
Sakuno,Natanael Rodolfo Ribeiro; Guiçardi,Augusto Cesar Ferreira; Spalevic,Velibor; Avanzi,Junior Cesar; Silva,Marx Leandro Naves; Mincato,Ronaldo LuizABSTRACT The water erosion process has a considerable negative effect on tropical soils, causes soil losses from arable land and reduces the capacity to support surrounding ecosystems. Estimating soil losses caused by water erosion is fundamental for evaluating the impacts of various production systems. Therefore, improving soil loss estimates via the adaptation of models for different edaphoclimatic environmen...
SIMULATING THE EFFECT OF PERMANENT PRESERVATION AREAS ON SOIL EROSION RATES
Lense,Guilherme Henrique Expedito; Moreira,Rodrigo Santos; Parreiras,Taya Cristo; Silva,Luis Felipe Pigatto Miranda; Teodoro,Alexandre Elias de MirandaABSTRACT Water erosion is one of the main problems faced by the Furnas Lake Surrounding Watershed, located in southeast Brazil. The erosive process is intensified by inadequate land occupation of the lake margins where should be riparian forests, or permanent preservation areas (APP), in order to protect water resources. In this context, our work aimed to estimate the soil losses of this watershed using the Rev...
Nutritional status and physiological parameters of maize cultivated with sewage...
Moreira,Rodrigo Santos; Lense,Guilherme Henrique Expedito; Fávero,Leonardo Ferreira; Oliveira Junior,Benedito Majela de; Mincato,Ronaldo LuizABSTRACT The use of sewage sludge as a source of nutrients and organic matter for agricultural soils is a well-established practice. However, few reports highlight the effect of the nutrients and potentially toxic elements provided by organic wastes application on the plant physiological parameters, such as photosynthetic activity and stomatal conductivity. We performed a greenhouse experiment with maize expose...
Estimation of sediments produced in a subbasin using the Normalized Difference ...
Lense,Guilherme Henrique Expedito; Moreira,Rodrigo Santos; Bócoli,Fernanda Almeida; Avanzi,Junior Cesar; Teodoro,Alexandre Elias de MirandaABSTRACT Among the parameters considered by the Revised Universal Soil Loss Equation (RUSLE), the soil cover and management factor (C) is the main human influenced factor affecting the estimation of water erosion, and one of the most sensitive to spatiotemporal variations. Consequently, this study aims to compare the efficiency of C factor estimates obtained from the literature for each land-use class (Clit) an...
Estimates of soil losses by the erosion potential method in tropical latosols
Lense,Guilherme Henrique Expedito; Parreiras,Taya Cristo; Moreira,Rodrigo Santos; Avanzi,Junior Cesar; Mincato,Ronaldo LuizABSTRACT Water erosion is one of the main problems faced in coffee cultivation, as it promotes environmental degradation and crop yield decrease. Erosion estimates support the planning of conservation management practices and allowing determining the rates of soil losses. Thus, the objective of this paper was to estimate the soil loss by water erosion using the Erosion Potential Method in a sub-basin predominan...
