“…Therefore, any change in microbial composition or activity influence soil fertility and plant growth (Crecchio et al 2007). Microbial biomass and soil enzymes are considered as potential indicators of soil quality due to their relationship to soil biology, ease of measurement, rapid responses to changes in soil management and high sensitivity to changes originated by management and environment factors (Marx et al 2001;Jimenez et al 2002;Garcia-Alvarez and Ibanez 1994;Karlen et al 1997;Franchini et al 2007).…”

A field experiment was conducted on sandy clay-loam soil at New Delhi, during 2004 and to investigate the effect of irrigation regimes, namely, continuous submergence, one-day drainage, and three-day drainage, and integrated nutrient management practices on the soil biological health parameters under rice cultivation. The non-puddled soils showed significantly high soil respiration (17.32%) and soil microbial biomass carbon (45.51%) activity than the puddled soils. However, the soil dehydrogenase enzyme activity was 65.26% higher under puddled soils than the nonpuddled. Among the integrated nitrogen management, substitution of 25% recommended dose of nitrogen (RDN) as biofertilizer resulted in highest (560.02 mg TPF g 71 soil 24 h 71 ) enzyme dehydrogenase (DH) activity and application of entire RDN as organics supported the highest soil microbial biomass carbon (218.29 mg g 71 soil) and respiration activity (56.67 mg CO 2 [100 g 71 soil 24 h 71 ). In comparison with other organic N inputs, substitution of sewage-sludge for 25% RDN resulted in the least soil respiration (47.67 mg CO 2 100 g 71 soil 24 h 71 ), low DH enzyme activity (313.37 mg TPF g 71 soil 24 h 71 ) and soil microbial biomass carbon content (183.85 mg g 71 soil). The present study suggests that inorganic, organic and bio-fertilizer combinations significantly improved soil health parameters.

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 ...

The field experiments were conducted on sandy loam soil at New Delhi, during 2007 and to investigate the effect of conservation tillage, irrigation regimes (sub-optimal, optimal and supra-optimal water regimes), and integrated nutrient management (INM) practices on soil biological parameters in wheat cultivation. The conservation tillage soils has shown significant (p<0.05) increase in soil respiration (81.1%), soil microbial biomass carbon (SMBC) (104%) and soil dehydrogenase (DH) (59.2%) compared to the conventional tillage soil. Optimum water supply (3-irrigations) enhanced soil respiration over sub-optimum and supra-optimum irrigations by 13.32% and 79% respectively. Soil dehydrogenase (DH) activity in optimum water regime has also increased by 23.33% and 8.18% respectively over the other two irrigation regimes. Similarly, SMBC has also increased by 12.14% and 27.17% respectively in soil with optimum water supply compared to that of sub-optimum and supra-optimum water regime fields. The maximum increase in soil microbial activities is found when sole organic source (50% Farm Yard Manure+25% biofertilizer+25% Green Manure) has been used in combination with the conservation tillage and the optimum water supply. Study demonstrated that microbial activity could be regulated by tillage, water and nitrogen management in the soil in a sustainable manner.
