Resumo: | The evaluation of soil quality is an important tool to monitor their degradation and to sustainable practices implementation, by indicators that can relate to soil quality with agricultural activity. The Caatinga, an exclusively Brazilian biome, has a high degradation rate, resulting of human action in inadequate soil management. The objective was to evaluate changes of chemical and biological indicators of organic matter due to the seasonality in preserved and disturbed areas of Caatinga ecoregions in Pernambuco, as well as qualitative characteristics of soil organic matter in these environments and uses. Three areas were selected: one in Buíque and two in Serra Talhada, in each area were studied two conditions of land use (soil in areas with preserved Caatinga coverage and areas with agricultural use).Soil samples were collected between September/2014 and September/2015, covering dry and rainy seasons in semiarid region. In each use and area, there were collected three composite soil samples at layers 0-5, 5-10 and 10-20 cm. Analysis to chemical and physical soil characterization were carried out in addition to biological analysis of total organic carbon (TOC), labile fractions of oxidizable carbon (LFCO), microbial biomass carbon (MBC), basal soil respiration (BSR), microbial quotient (qMIC), physical fractionation of organic matter (POM), physical fractionation of organic matter associated with mineral (MOM) and chemical fractionation of humic substances (HS).Data were analyzed by T test, at 5% probability. It was observed that all relevant variables are influenced by seasonality, and soil texture to LFCO, MBC and TOC, indicating a greater influence on labile carbon fractions.While the characterization by FTIR set directly related to carbon in MOP fractions with AH and AF, and MOM with humin. |

Dissertação (Programa de Pós-Graduação em Produção Agrícola) - Universidade Federal Rural de Pernambuco, Garanhuns.http://www.tede2.ufrpe.br:8080/tede2/handle/tede2/6551The evaluation of soil quality is an important tool to monitor their degradation and to sustainable practices implementation, by indicators that can relate to soil quality with agricultural activity.

A Caatinga, um bioma exclusivamente brasileiro, tem um alto índice de degradação, resultado da ação antrópica de manejo inadequado do solo. O objetivo da pesquisa foi de avaliar as alterações dos indicadores químicos e biológicos da matéria orgânica em função da sazonalidade, em áreas preservadas e antropizadas de ecorregiões da Caatinga em Pernambuco, bem como características qualitativas da matéria orgânica do solo nesses ambientes e usos. Para tanto, foram selecionadas três áreas: uma em Buíque e duas em Serra Talhada, em cada área foram estudadas duas condições de uso do solo (solos em áreas com cobertura de Caatinga preservada e áreas com uso agrícola). As coletas foram realizadas entre setembro/2014 e setembro/2015, abrangendo a estações seca e chuvosa dessas áreas no semiárido. Em cada uso, por área, foram coletadas três amostras compostas de solo nas camadas de 0-5, 5-10 e 10-20 cm. Foram realizadas análises de caracterização química e física dos solos, além das análises biológicas de carbono orgânico total (COT), frações lábeis de carbono oxidáveis (FLCO), carbono da biomassa microbiana (CBM), respiração basal do solo (RBS), quociente microbiano (qMIC), fracionamento físico da matéria orgânico (MOP), fracionamento físico da matéria orgânica associada aos minerais (MOM) e fracionamento químico das substâncias húmicas (SH). Os dados foram analisados pelo teste T, ao nível de 5% de probabilidade. Observou-se que todas as variáveis obtidas são influenciadas pela sazonalidade e pela textura do solo para FLCO, CBM e COT, indicando maior influência sobre as frações de carbono lábeis. Enquanto a caracterização por FTIR define relação direta com carbono nas frações de MOP com AH e AF, e MOM com humina.Submitted by Mario BC (mario@bc.ufrpe.br) on 2017-03-07T13:12:05Z No. of bitstreams: 1 Luciana Maria Herculano da Silva.pdf: 1397632 bytes, checksum: cca869a58fb4ebdc78f6d4d8be57f51f (MD5)Made available in DSpace on 2017-03-07T13:12:06Z (GMT).

The evaluation of soil quality is an important tool to monitor their degradation and to sustainable practices implementation, by indicators that can relate to soil quality with agricultural activity. The Caatinga, an exclusively Brazilian biome, has a high degradation rate, resulting of human action in inadequate soil management. The objective was to evaluate changes of chemical and biological indicators of organic matter due to the seasonality in preserved and disturbed areas of Caatinga ecoregions in Pernambuco, as well as qualitative characteristics of soil organic matter in these environments and uses. Three areas were selected: one in Buíque and two in Serra Talhada, in each area were studied two conditions of land use (soil in areas with preserved Caatinga coverage and areas with agricultural use).Soil samples were collected between September/2014 and September/2015, covering dry and rainy seasons in semiarid region. In each use and area, there were collected three composite soil samples at layers 0-5, 5-10 and 10-20 cm. Analysis to chemical and physical soil characterization were carried out in addition to biological analysis of total organic carbon (TOC), labile fractions of oxidizable carbon (LFCO), microbial biomass carbon (MBC), basal soil respiration (BSR), microbial quotient (qMIC), physical fractionation of organic matter (POM), physical fractionation of organic matter associated with mineral (MOM) and chemical fractionation of humic substances (HS).Data were analyzed by T test, at 5% probability. It was observed that all relevant variables are influenced by seasonality, and soil texture to LFCO, MBC and TOC, indicating a greater influence on labile carbon fractions.While the characterization by FTIR set directly related to carbon in MOP fractions with AH and AF, and MOM with humin. |
