“…They are direct measures of the biological metabolism of soil biota (Burns et al, 2013;Das and Varma, 2011;Dick and Kandeler, 2005). Their activities can indicate microbial activity, decay rates, and availability of substrates for microbial or plant uptake (Garcia-Gil et al, 2000;Lagomarsino et al, 2009). Activities of β-1,4-glucosidase (βG), β-1,4-N-acetylglucosaminidase (NAG), leucine aminopeptidase (LAP), and acid (alkaline) phosphatase (AP) control the release of biologically available nutrients from organic compounds of carbon (C), N, and P (Sinsabaugh et al, 2008(Sinsabaugh et al, , 2010Zhou et al, 2012).…”

“…Enzyme activities related to C, N, and P nutrient cycling in soils often increase when organic materials are added (Böhme et al, 2005;Debosza et al, 1999;Garcia-Gil et al, 2000). Organic amendments can stimulate plant growth and microbial activity (Ge et al, 2010;Nayak et al, 2007); protect and maintain soil enzymes in their active forms; serve as readily available sources of energy and nutrients that enhance microbial and crop biomass (Bhattacharyya et al, 2005;Bi et al, 2009), and provide substrates for living microorganisms (Dalal, 1982;Saha et al, 2008).…”

• Acid phosphatase activity was negatively correlated with soil pH and P content.• βG, NAG, and LAP activities were positively correlated with SOC and Total N contents.• The four enzyme activities were significantly higher under manure than NPK fertilizer.• Enzyme activities were positively correlated with actinomycete and G + bacterium.• We recommend reducing P fertilizer application rates to subtropical paddy soils. G R A P H I C A L A B S T R A C Ta b s t r a c t a r t i c l e i n f o Long-term phosphorus (P) and nitrogen (N) applications may seriously affect soil microbial activity. A long-term field fertilizer application trial was established on reddish paddy soils in the subtropical region of southern China in 1998. We assessed the effects of swine manure and seven different rates or ratios of NPK fertilizer treatments on (1) the absolute and specific enzyme activities per unit of soil organic carbon (SOC) or microbial biomass carbon (MBC) involved in C, N, and P transformations and (2) their relationships with soil environmental factors and soil microbial community structures. The results showed that manure applications led to increases in the absolute and specific activities of soil β-1,4-glucosidase(βG), β-1,4-N-acetylglucosaminidase (NAG), and leucine aminopeptidase (LAP). The absolute and specific acid phosphatase (AP) activities decreased as mineral P fertilizer application rates and ratios increased. Redundancy analysis (RDA) showed that there were negative correlations between absolute and specific AP activities, pH, and total P contents, while there were positive correlations between soil absolute and specific βG, NAG, and LAP enzyme activities, and SOC and total N contents. RDA showed that the contents of actinomycete and Gram-positive bacterium PLFA biomarkers are more closely related to the absolute and specific enzyme activities than the other PLFA biomarkers (P b 0.01). Our results suggest that both the absolute and specific enzyme activities could be used as sensitive soil quality indicators that provide useful linkages with the microbial community structures and environmental factors. To maintain microbial activity and to minimize environmental impacts, P should be applied as a combination of inorganic and organic forms, and total P fertilizer application rates to subtropical paddy soils should not exceed 44 kg P ha −1 year −1 .

“…Em relação à atividade da DHA, a aplicação das doses de 750 kg ha -1 e 3.000 kg ha -1 de XR provocaram redução na atividade dessa enzima, somente na avaliação realizada aos sete dias, do segundo cultivo de feijão. Os valores obtidos para a atividade das enzimas avaliadas estão dentro de uma ampla faixa de valores, obtidos em trabalhos com diferentes formas de uso do solo e em distintas condições edafoclimáticas (García-Gil et al, 2000;Marcote et al, 2001;Trannin et al, 2007;Lagomarsino et al, 2009).…”

“…Alterações na qualidade do solo, provocadas pela aplicação de subprodutos, são frequentemente avaliadas por meio das características biológicas do solo (García-Gil et al, 2000;Trannin et al, 2007;Lambais & Carmo, 2008;Souza et al, 2009). Em geral, a quantidade de C na biomassa microbiana, o quociente metabólico (qCO 2 ) e a atividade enzimática do solo são indicadores sensíveis e precoces de distúrbios naturais e antropogênicos (Lambais & Carmo, 2008;Lagomarsino et al, 2009).…”

Resumo -O objetivo deste trabalho foi avaliar o efeito da aplicação de doses crescentes de xisto retortado (XR) sobre características biológicas indicadoras da qualidade do solo. Foram realizados experimentos, em Argissolo Vermelho distrófico arênico, em condições de laboratório e de campo. Em laboratório, os tratamentos consistiram da aplicação ao solo de sete diferentes doses de XR (0, 300, 450, 600, 750, 1.500 e 3.000 kg ha -1 ). Em campo, os tratamentos foram compostos por quatro diferentes doses de XR (0, 750, 1.500, 3.000 kg ha -1 ) combinadas à adubação mineral recomendada, avaliados em dois cultivos de feijão (Phaseolus vulgaris L.), no sistema plantio direto. Avaliaram-se: a evolução de CO 2 , o carbono da biomassa microbiana (CBM), a atividade enzimática do solo e o teste de ecotoxicidade. A aplicação de doses crescentes de XR melhorou a atividade microbiológica do solo, por reduzir a emissão de CO 2 sem causar variação no CBM e sem provocar impactos negativos sobre a atividade enzimática do solo. Os resultados obtidos com as enzimas em condições de campo, após duas aplicações de XR, aliados aos de CBM, do quociente metabólico (qCO 2 ) e do teste ecotoxicológico, em condições de laboratório, indicam que o uso do XR não provoca a degradação biológica do solo.Termos para indexação: biomassa microbiana, ecotoxicidade, enzimas do solo, mineralização do carbono, qualidade do solo. Microbial and enzymatic activities in the soil after application of retorted oil shaleAbstract -The objective of this study was to assess the effect of increasing doses of retorted oil shale (ROS) application on the biological property indicators of soil quality. Experiments were carried out, under field and laboratory conditions, on a Hapludalf soil. In the laboratory, the treatments consisted of the application of seven different ROS rates (0, 300, 450, 600, 750, 1,500 and 3,000 kg ha -1 ) to the soil. In the field, the treatments were composed by four different ROS rates (0, 750, 1,500 and 3,000 kg ha -1 ) combined with the recommended mineral fertilizer rate, evaluated in two croppings of common bean (Phaseolus vulgaris L.), under no-till system. CO 2 evolution, microbial biomass carbon (MBC), soil enzyme activity and the ecotoxicity test were evaluated. Application of increasing ROS rates improved the soil microbial activity by decreasing CO 2 emission and causing no variations in MBC nor negative impacts on the soil enzymatic activity. The results obtained with the enzymes under field conditions, after two ROS applications, allied to MBC results, and to the metabolic quocient (qCO 2 ) and to the ecotoxicity test, under laboratory conditions, show that the use of ROS cause no soil biological degradation.

Land/water ecotones, the transitional boundary zone between terrestrial and aquatic ecosystems, can effectively trap and assimilate nutrients from external sources. The changes of nutrient cycling will cause a response in enzyme activity. In this paper, the enzyme kinetics of land/water ecotones in a shallow eutrophic wetland in China, dominated by a reed (Phragmites australis) community, are studied. The results indicate that land/water ecotones exhibit a strong filtration function and nutrient factor is an important feature affecting the distribution of enzymes in the transect of the littoral zone. The obvious spatial differences of enzyme activities and nutrients are present in the transect of the reed beds. The land area is the hot zone, where significant changes in enzyme activity occur. T-test results show that the landward spot, 1 m away from the water-land interface, is quite different from other spots, and the 1 m spot is the hot spot where great biochemical change happens. The principal component analysis of the environmental variables shows that nutrient factors have an important affect on enzyme distribution in the transect of the littoral zone. The nutrient factor explains about 54% of the observed variance. In particular, TOC (total organic carbon) correlates with the other five factors (TN; total nitrogen, TP; total phosphorus, phosphatase, b-glucosidase, and urease) with correlative coefficients of 0.932, 0.595, 0.488, 0.433, and -0.468, respectively. The results indicate that TOC is a very important factor in Baiyangdian wetlands.
