“…Estas condições podem levar ao desequilíbrio da comunidade microbiana, proporcionando condições de estresse (Anderson e Domsch, 1993;Santos et al, 2015), resultando em maiores perdas de CO 2 e menor incorporação de carbono ao tecido celular (Barbosa, 2010).…”

Compreender o comportamento e a dinâmica dos microrganismos do solo ajuda a avaliar as práticas de uso do solo que mantém e/ou melhoram a qualidade deste ao longo do tempo. O objetivo deste trabalho foi avaliar a qualidade do solo de diferentes áreas com base na biomassa microbiana, respiração basal e índices derivados (quociente metabólico e quociente microbiano) em dois períodos de amostragem. Quatro amostras compostas oriundas de três subamostras de solo foram coletadas nos anos de 2012 e 2014 na camada de 0,00-0,10 m em sete áreas distintas, sendo cinco áreas em restauração ecológica, um remanescente de floresta nativa e uma área de cultivo de cana-de-açúcar. Os dados foram submetidos à análise de variância, aplicando-se fatorial, sendo as médias comparadas pelo teste de Tukey, a 5% de significância e análise multivariada, por meio da agrupamento (Cluster Analysis). Os resultados indicam que, embora o tempo de resiliência das áreas em restauração ecológica seja relativamente curto, o desenvolvimento da cobertura vegetal e o estabelecimento da comunidade microbiana foram importantes para promover a melhoria da qualidade do solo.

“…High qCO 2 values can suggest an imbalance of the microbial community, changes in the metabolism of the organisms and ecosystems subjected to stress conditions or disorder (ANDERSON; DOMSCH, 1993;SANTOS et al, 2015), considering that under unfavorable conditions, the organisms require more energy (SCHIMEL et al, 2007) resulting in higher losses of CO 2 and lower incorporation of C in the tissue (ANDERSON; DOMSCH, 1993). The qCO 2 values of other evaluated areas did not differ signifi cantly, indicating that SOM is stabilized.…”

ABSTRACT:A challenge for the environmental recovery of degraded areas is the search for soil data. In this process, the microbiological parameters and soil chemicals are potential indicators of soil quality. This study aimed to evaluate soil quality based on microbiological and chemical soil attributes in different areas involving environmental recovery, sugarcane cultivation and remnants of native vegetation located in a rural private property farm in State of Mato Grosso do Sul, Brazil, in Hapludox Eutrophic soil. The microbiological (microbial biomass carbon, basal respiration, microbial quotient and metabolic quotient) and chemical parameters (organic matter, carbon, pH, cationic exchange capacity, sum of bases, potassium, phosphorus, magnesium, calcium, saturation base and potential acidity) were assessed. Data were assessed by variance and multivariate analysis (Principal Component Analysis and cluster analysis). Overall, the results showed highest alteration in the chemical and microbiological characteristics of the soil in sugarcane cultivation area in comparison with other areas. Considering the studied recovery areas, REC1, REC5 and REC7 show chemical and microbiological conditions with most similarity to native vegetation. Despite the short period of the resilience enhancement of environmental recovery areas, the development of vegetation cover and establishment of the microbial community were determined to be important factors for improving soil quality and environmental recovery in several of the areas studied. ATRIBUTOS QUÍMICOS E MICROBIOLÓGICOS SOB DIFERENTES COBERTURAS DE SOLORESUMO: Um desafio para a recuperação ambiental de áreas degradadas é a busca de dados de solo. Neste processo, os parâmetros microbiológicos e química do solo são potenciais indicadores de qualidade do solo. Este estudo objetivou avaliar a qualidade do solo com base em atributos microbiológicos e químicos do solo em diferentes áreas, em recuperação ambiental, cultivo de cana e remanescentes de vegetação nativa, localizada em uma fazenda de propriedade privada rural no estado de Mato Grosso do Sul, Brasil, em solo Háplico Eutrófico. Os parâmetros microbiológicos (carbono da biomassa microbiana, respiração basal, quociente microbiano e quociente metabólico) e químicos (matéria orgânica, carbono, pH, capacidade de troca de cátions, soma de bases, potássio, fósforo, magnésio, cálcio, saturação por bases e acidez potencial) foram acessados. Dados foram avaliados por meio de análises de variância e multivariada (análise de agrupamentos e Análise de Componentes Principais). Em geral, os resultados mostraram maior alteração das características químicas e microbiológicas do solo na área de cultivo de cana em comparação com outras áreas. Considerando as áreas em recuperação estudadas, REC1, REC5 e REC7 mostram condições químicas e microbiológicas com maior semelhança com a vegetação nativa. Apesar do curto período do realce de resiliência das áreas de recuperação ambiental, o desenvolvimento da cobertura vegetal e o estabelecimento ...

“…Changes in soil properties can vary with climatic conditions, soil type, crop rotation, and the duration of the amendment period (Clark et al, 1998). A decrease in the amount of organic inputs results in a decline in organic matter content of soil, thereby reducing available organic substrate for soil organisms with consequent disruption of essential soil functions, especially nutrient cycling (Santos et al, 2015;Miransari, 2013) and soil aggregation (Biswas et al, 2014;Jiao et al, 2006).…”

In certified organic agricultural systems, soil nutrient status relies primarily on incorporation of organic matter and other specific inputs to meet requirements for phosphorus and micronutrients. Nutrient management strategies based on defined standards seek to maintain sufficient nutrient availability while minimizing potential losses. Although organic systems may result in lower levels of production than conventionally managed systems, sound soil nutrient management practices can minimize this gap. Certified organic standards are widely established globally, but traditional farming practices that resemble organic systems are also commonly used without adherence to a certified scheme. There is considerable debate about the efficiency of bio-amendments for use in organic farming due to their variability. Questions also persist about the sustainability of organic soil fertility management practices. The relevance of global variations among organic certification standards has not been a major consideration in research. Most soil improvement strategies focus on assessing the impact of particular amendments with less attention to a more holistic approach which integrates all components of the agricultural system. Research on implementation of practices based on certified organic standards highlights potential for multi–disciplinary, in-depth studies that identify combined impacts of organic management practices at a local scale. Standards developed at national level may not fully account for the breadth of soil types and environmental conditions. While soil improvement based on certified organic standards can contribute to socio-economic development and ecosystem services, local soil characteristics need to be considered in parallel with potential new avenues for sourcing nutrients, including organic matter management.
