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 ...

“…Red soil 1 Background, aim, and scope Soil quality has been used as an important indicator of ecosystem health and sustainability of agroecosystems. It can be assessed using soil physical, chemical, and biological approaches (Karlen et al 2003). Soil microbial composition and diversity have been considered to be one of the most sensitive biological indicators for measuring soil quality (Kennedy 1999).…”

Microbial composition and diversity of an upland red soil under long-term fertilization treatments as revealed by culture-dependent and culture-independent approaches

Background, aim, and scope Fertilization is an important agricultural practice for increasing crop yields. In order to maintain the soil sustainability, it is important to monitor the effects of fertilizer applications on the shifts of soil microorganisms, which control the cycling of many nutrients in the soil. Here, culture-dependent and cultureindependent approaches were used to analyze the soil bacterial and fungal quantities and community structure under seven fertilization treatments, including Control, Manure, Return (harvested peanut straw was returned to the plot), and chemical fertilizers of NPK, NP, NK, and PK. The objective of this study was to examine the effects on soil microbial composition and diversity of long-term organic and chemical fertilizer regimes in a Chinese upland red soil. Materials and methods Soil samples were collected from a long-term experiment station at Yingtan (28°15′N, 116°55′E), Jiangxi Province of China. The soil samples (0-20 cm) from four individual plots per treatment were collected. The total numbers of culturable bacteria and fungi were determined as colony forming units (CFUs) and selected colonies were identified on agar plates by dilution plate methods. Moreover, soil DNAs were extracted and bacterial 16S rRNA genes and fungal 18S rRNA genes were polymerase chain reaction amplified, and then analyzed by denaturing gradient gel electrophoresis (DGGE), cloning, and sequencing. Results The organic fertilizers, especially manure, induced the least culturable bacterial CFUs, but the highest bacterial diversity ascertained by DGGE banding patterns. Chemical fertilizers, on the other hand, had less effect on the bacterial composition and diversity, with the NK treatment having the lowest CFUs. For the fungal community, the manure treatment had the largest CFUs but much fewer DGGE bands, also with the NK treatment having the lowest CFUs. The conventional identification of representative bacterial and fungal genera showed that long-term fertilization treatments resulted in differences in soil microbial composition and diversity. In particular, 42.4% of the identified bacterial isolates were classified into members of Arthrobacter. For fungi, Aspergillus, Penicillium, and Mucor were the most prevalent three genera, which accounted for 46.6% of the total identified fungi. The long-term fertilization treatments resulted in different bacterial and fungal compositions ascertained by the culture-dependent and also the culture-independent approaches. Discussion It was evident that more representative fungal genera appeared in organic treatments than other treatments, indicating that culturable fungi were more sensitive to organic than to chemical fertilizers. A very notable finding was that fungal CFUs appeared maximal in organic manure treatments. This was quite different from the

“…La Soil Science Society of America (SSSA, 1997), Schoenholtz et al (2000), Karlen et al (2003) y Andrews et al (2004) definen la calidad del suelo como "la capacidad de éste para funcionar dentro de los límites de un ecosistema para sostener la productividad biológica, mantener la calidad ambiental y promover la salud de plantas y animales". Además, afirman que la calidad en un suelo depende de sus propiedades, de su uso y o las prácticas de manejo de la tierra.…”

“…Ellos deben dar información útil para conocer el funcionamiento del suelo, ser accesibles para los usuarios y aplicables a las condiciones de manejo y clima en campo y ser económico de medir. Los indicadores son seleccionados de un conjunto de propiedades físicas, químicas y biológicas del suelo y forman el "conjunto mínimo de datos" (MDS) (Doran & Parkin, 1994;Schoenholtz et al, 2000;Karlen et al, 2003;Bastida et al, 2008;Wienhold, 2009). …”

Se evaluaron algunas propiedades edáficas y foliares en 50 fincas cafeteras de seis municipios de Antioquia. Se determinaron dos índices de la calidad del suelo relacionados con la calidad de la taza de café mediante dos conjuntos de indicadores seleccionados por análisis de componentes principales (MDS1) y análisis de factores (MDS2). El contenido de azufre (S), la actividad enzimática (AE), el índice de Shanoon (ISh), la respirometría (CO2) y los contenidos foliares de N (Nf), Mg (Mgf) y S (Sf) fueron indicadores comunes a los dos índices. Los mejores índices se presentaron en Ciudad Bolívar, finca La Carolina: ICS1 (1,32) e ICS2 (4,32). Los índices más bajos estuvieron en Urrao: ICS1 (finca El Cadillal: 0,82) e ICS2 (fincas El Rosal y El Cadillal: 2,50). El mayor índice general promedio lo presentó el ICS2 (3,19) y el menor el ICS1 (1,05). Se presentaron diferencias significativas en los índices entre ellos y entre núcleos. Se recomienda el uso del ICS2 por ser mayor y requerir menos variables: más económico y fácil de determinar.
