1. Least limiting water range in Oxisol under two conservation tillage systems in sugarcane farming
ABSTRACT The Least Limiting Water Range (LLWR) is an indicator of soil physical quality, contributing in information to propose soil management systems in agricultural farming process. This work aimed to assess the usage of LLWR and critical soil bulk density for physical-water quality evaluations, as well as its effect on sugarcane farming under no-tillage

2. CHARACTERIZATION OF GEOSPATIAL, MORPHOMETRIC, AND ENVIRONMENTAL DYNAMICS OF THE MARIANA MICROBASIN IN ALTA FLORESTA-MT, BRAZIL
ABSTRACT River basin environmental diagnosis and monitoring are fundamental for water resource use and conservation plans, as these systems integrate different landscape elements and may undergo impacts and changes of different levels and scales. In this context, this work aimed to characterize the geospatial, morphometric, and environmental dynamics in the

3. FLORISTIC COMPOSITION AND DIVERSITY IN TERRA FIRME FOREST UNDER WATER STRESS IN THE AMAZON
ABSTRACT The studies on floristic composition are an aid in the understanding of the structure and dynamics of the plant communities, fundamental parameters for its management and conservation. Thus, the objective of this work was to evaluate the floristic composition, species richness, Shannon’s diversity and models of species abundance over a 10-year per

5. Diametric Growth of Tree Species in the Atlantic Forest, Paraná, Brazil
Abstract: Management of remnants in Atlantic Forest is an alternative for their conservation, however, information on the growth and ecology of those species is lacking. This study aimed to describe diametric growth of Balfourodendron riedelianum, Cordia trichotoma and Ocotea diospyrifolia based on its growth rings and to verify the relationship between this

6. Soil conservation practices in a watershed in Southern Brazil
Abstract: The aim of this study was to determine how often rural farmers in a watershed use no-tillage systems combined with crop rotation, contour farming and agricultural terraces. The study area was Paraná Watershed III (PB3) in the western region of Paraná State, and data from the 2006 Agricultural Census of the Brazilian Institute of Geography and Sta

7. Definition of priority areas for soil and water conservation in the Itanguá watershed, Capão Bonito, SP state, Brazil
Resumo O uso inadequado dos solos pode provocar erosão e assoreamento dos cursos d’água reduzindo assim a quantidade e a qualidade da água na bacia. A implantação de práticas conservacionistas de solo e a presença de vegetação nativa são ações de fundamental importância para a conservação do solo e água na bacia, uma vez que elas atuam dimi

8. Estimates of soil losses by the erosion potential method in tropical latosols
RESUMO A erosão hídrica é um dos principais problemas enfrentados na cafeicultura, pois promove a degradação ambiental e a diminuição da produção agrícola. As estimativas da erosão auxiliam no planejamento de práticas e sistemas de manejo conservacionistas e permitem aferir as taxas de perdas do solo. Assim, o objetivo do trabalho foi estimar a p

9. Modeling of the Rainfall and R-Factor for Tocantins State, Brazil
ABSTRACT The state of Tocantins is inserted in the new Brazilian agricultural frontier and has shown enormous potential for expansion of the agricultural lands. However, there is a lack of more elaborate scientific information for better planning and guide agricultural activities, especially regarding the soil and water conservation. Tocantins has a relevant

10. The relationship between plant density and survival to water stress in seedlings of a legume tree
ABSTRACT Competition for soil water is one of the major processes that drive the assembly of plant communities, particularly in regions subjected to long dry seasons. The relationship between plant density and soil water competition has strong, but poorly understood, practical implications for population dynamics, restoration and conservation. We planted see

11. Impact of pig slurry application on soil and water losses: Comparison with a historical series
RESUMO A erosão hídrica no solo é influenciada por diversos fatores, incluindo chuva, relevo, cobertura, e manejo e práticas conservacionistas. Ainda, a erosão é afetada pelo dejeto suíno (DS) aplicado ao solo como fertilizante. Os objetivos desta pesquisa foram i): avaliar a erosão em Cambissolo Húmico, após aplicação de DS sob diferentes tratam

12. Relationship Among Crop Systems, Soil Cover, and Water Erosion on a Typic Hapludox
ABSTRACT Several soil conservation practices are used to reduce water erosion and ensure sustainable agriculture. An effective crop management practice is intercropping, in which two or more crops with different architectures and vegetative cycles are grown simultaneously in the same area. We hypothesized that intercropping of corn and jack-bean increases so
