ABSTRACT Brazilian Soil Classification System (SiBCS) adopts a hierarchical approach to classify soils using specific diagnostic attributes. Organossolos (Histosols) class is differentiated according its genesis, especially because the parent material organic, thus requiring attributes that describe unique properties of soil organic matter (SOM). This study aimed propose use labile carbon and C N contents humic fractions their ratios for family series levels in high mountainous regions....
Objective: This study aimed to obtain the Bd of organic constitution horizons through PTFs and evaluate C N stocks different soil classes found in upper part INP. Theoretical framework: The evaluation bulk density (Bd) depends on method used sample presents great spatial variability, especially mountainous regions such as Itatiaia National Park (INP), Brazil. Techniques can be for this purpose, including those pedotransfer functions (PTFs) allowing quantification nutrients soils....
A degradacao de uma area natural, independentemente suas causas, pode ser verificada quando a vegetacao e por consequencia, fauna, sao degradadas, removidas ou expulsas do seu ecossistema bem como camada solo rico em nutrientes minerais perdida, removida coberta, afetando diretamente as relacoes ecologicas existentes nesse ecossistema. Objetivou-se diagnosticar possiveis causas processo situada no municipio Corrente, Piaui sob fitogeografia Cerrado propor intervencoes para recuperacao desta...
This work aimed to analyze the dynamics of soil carbon in agricultural areas under different management systems and natural ecosystems with Cerrado vegetation. The study was carried out a grain production area equivalent soybeans corn located Western region Bahia State adoption conventional no-tillage + Brachiaria vegetable southernmost tip Piauí organic cultivation no-tillage, besides native the Cerrado. Total C content, light matter, matter were evaluated. Furthermore, stock assessed at...
Rainfall simulators are important pieces of equipment to investigate hydrological processes and soil erosion. Here, we investigated the operational characteristics, rainfall erosion process under collecting plots patterns using InfiAsper simulator. We evaluated standard plot simulator in a rectangular shape (1.0 × 0.7 m), as well circular (0.8 m diameter), four precipitation patterns, characterized advanced (AV), intermediate (IN), delayed (DL), constant (CT). In laboratory, uniformity water...
A estimativa do banco de sementes da população infestante é importante na elaboração estratégias controle plantas daninhas que interferem produção das culturas. Objetivou-se com este trabalho realizar o levantamento composição específica vegetação constitui cultura feijão-caupi quando associada a aplicação palha babaçu e herbicidas. O delineamento experimental foi em blocos ao acaso quatro repetições, os tratamentos dispostos esquema simples, distribuídos dois herbicida (bentazon...
