“…Soil organic matter is recognized as one of the most important factors in the assessment of soil quality and conditioning, being constituted by several fractions (Gregorich et al, 1997;Nortcliff, 2002;Bastida et al, 2008). Although the determination of total organic carbon (TOC) content alone cannot express the changes resulting from soil use in certain situations, it is often used to quantify SOM levels and changes (Figueiredo et al, 2010).…”

Veredas are humid tropical ecosystems, generally associated to hydromorphic soils and a shallow water table. The soils of these ecosystems are affected by the use of the areas around these veredas. The objective of this study was to determine soil organic matter (SOM) fractions in veredas adjacent to preserved (native savanna) and disturbed environments (agricultural areas and pastures) in the Cerrado biome. Soil samples were collected from the 0-10 and 10-20 cm layers along reference lines drawn along the relief following the upper, middle and lower positions of one of the slopes, in the direction of the draining line of the vereda. The soil analysis determined: total soil OC, total nitrogen and C:N ratio; C and N contents and C:N ratio in particulate and mineral-associated fractions (of SOM); fulvic acids, humic acids and humin fractions and ratio between humic and fulvic acids. The agricultural use around the veredas induced changes in the SOM fractions, more pronounced in the lower part of the slope. In the soil surface of this part, the OC levels in the humic substances and the particulate fraction of SOM, as well as total soil OC were reduced in the vereda next to crop fields. Keywords

“…O conceito de qualidade do solo mais largamente aceito, segundo Nortcliff (2002), é com relação à produção agrícola. Nesse contexto, Karlen et al (1997) definem qualidade de solo como sendo sua adaptação para funcionar com o ambiente, sustentar a produtividade vegetal e animal, manter ou melhorar a qualidade da água e do ar, e sustentar a sobrevivência do homem.…”

RESUMOEstudos de qualidade do solo são importantes para o entendimento da interação dessa com o ecossistema como um todo. Nesse contexto, os microrganismos do solo desempenham papel fundamental para manutenção e produtividade de vários agroecossistemas. Objetivou-se, neste trabalho avaliar os atributos biológicos (carbono da biomassa microbiana, respiração basal e quociente microbiano), além do teor de carbono orgânico, possíveis indicadores das alterações na qualidade do solo impostas pelos diferentes sistemas de manejo, em relação ao cerrado nativo, em sistema agrossilvopastoril, no noroeste de Minas Gerais. Foram coletadas amostras, nas profundidades de 0-5, 5-20 e 20-40 cm, de um Latossolo Vermelho Distrófico típico (LVd), entre os municípios de Vazante e Paracatu. Os sistemas foram selecionados segundo o histórico de uso: (1) CN-cerrado nativo (testemunha); (2) EA-eucalipto + arroz (ano zero do sistema agrossilvopastoril, plantados após o desmatamento da vegetação nativa de cerrado); (3) ES-eucalipto + soja (ano um do sistema, semeadura da soja em substituição ao arroz); (4) EP-eucalipto + pastagem (ano dois do sistema, com pastagem de Brachiaria brizantha Stapf., para a engorda do gado de corte); (5) EPG-eucalipto + pastagem + gado de corte (ano três do sistema, com a introdução do gado de corte); (6) PP-pastagem plantada de Brachiaria brizantha Stapf.; e (7) EC-eucalipto no sistema convencional no espaçamento de 2,0 x 3,0 m. O carbono orgânico e o carbono da biomassa microbiana apresentaram valores mais elevados na camada superficial (0-5cm), em relação às demais, em todos os sistemas. O carbono orgânico mostrou alteração substancial em relação aos sistemas estudados e às profundidades, revelando seu potencial como indicador da qualidade do solo em termos de reflexos das modificações impostas pelo manejo. O teor de carbono da biomassa microbiana foi reduzido em todos sistemas estudados em relação ao cerrado nativo, em função da ação antrópica. Com o progresso do sistema agrossilvopastoril houve uma recuperação do carbono da biomassa microbiana. Não foi observada diferença significativa entre os sistemas de manejo e o cerrado nativo quanto ao quociente metabólico e à respiração basal. Termos para indexação:Carbono da biomassa microbiana, sistemas de manejo, cerrado. ABSTRACTSoil quality studies are important for understanding its interaction with the ecosystem as a whole.

This work had the objective to evaluate the biological attributes (microbial biomass carbon, basal respiration, and microbial quotient), as well as the organic matter content, possible indicators of alterations in soil quality imposed by different management systems, in relation to native cerrado, in agricultural -forestry -pasture system, in northwest of Minas Gerais state, Brazil. Samples were collected at 0-5, 5-20, and 20-40 cm depths, from a typical Dystrophic Red Latosol (Oxisol), between Vazante ...

“…As such communicative enzymes may be used to quantify the environmental effects of active protection applied to habitats of natural value . Ecosystem evaluation based on enzymatic tests does not merely offer the possibility to run a series of analyses but, furthermore, provides an opportunity to summarize the effects of numerous factors and to evaluate unique parameters such as cellular metabolites (Nortcliff 2002;Maurel and Ricard 2006;Bielińska et al 2008;Bielińska et al 2014;Oleszczuk et al 2014aOleszczuk et al , 2014b.…”

Abstract. This paper looks into the impact of free grazing by sheep and horses on the chemical and biological properties of soils in the partial protection zone of the Roztocze National Park. The study sampled three different types of pastureland in the area: pastures for sheep, horses and for combined grazing by sheep and horses. Compared to an ungrazed reference pasture, free grazing significantly stimulated the activity of enzymes which catalyze the transformation of organic matter (dehydrogenases, phosphatases and ureases) and it also positively influenced other chemical properties of the soils. Among the soils under free-grazing management, the pasture grazed to horses underwent the most advantageous changes in terms of the eco-chemical status of the soil.
