Available in PDF, EPUB and Kindle. Book excerpt: Studies were undertaken to investigate the long-term effects of lime application and tillage systems (no-till, ridge-till, and chisel plow) on soil microbial biomass C (C[subscript mic]) and N (N[subscript mic]) and the activities of glycosidases ([alpha]- and [beta]-glucosidases, [alpha]- and [beta]-galactosidases and [beta]-glucosaminidase); phosphatases (acid and alkaline phoshatases and phosphodiesterase); amidohydrolases (L-asparaginase, L-glutaminase, amidase, urease, and L-aspartase); and arylamidase at their optimal pH values. With the exception of acid phosphatase, which was significantly but negatively correlated, all other enzyme activities were significantly and positively correlated with soil pH values at four sites in Iowa. [Delta] activity/[Delta] pH values showed that among the enzymes studied [beta]-glucosidase, L-glutaminase, and acid phosphatase are the most sensitive to pH changes and could be used as tools for monitoring ecosystems health and function. The effect of crop rotations and N fertilization on [beta]-glucosaminidase activity and its relationship to N mineralization were studied in soils of two long-term field experiments in Iowa. The activity of [beta]-glucosaminidase was significantly affected by crop rotations and N fertilization, and was significantly correlated with C[subscript org] and N[subscript org], C[subscript mic], and N[subscript mic] in soils, and with cumulative N mineralized during 24 weeks of incubation at 30°C. Studies to evaluate the effects of 23 trace elements on the activity of [beta]-glucosaminidase in three Iowa surface soils showed that at 5 mmol kg−1 soil, the activity of this enzyme was inhibited by 18, and activated by 5, of the trace elements tested, with Ag(I) and Hg(II) being the most effective inhibitors. Also, the activity of this enzyme was significantly affected by tillage systems (no-till, chisel plow, and moldboard plow) and four residue placements (bare, normal, mulch, and double mulch). Other studies showed that the amounts of N mineralized in 56 surface soils, obtained from six states in the North Central region of the United States, by two biological and three chemical methods were significantly correlated with [beta]-glucosaminidase activity, and with organic C and total N. The amounts of N mineralized during 14 days of incubation of field-moist soils under waterlogged conditions at 30°C were the most significantly correlated with [beta]-glucosaminidase activity (r=0.86***).

Book excerpt: This book addresses issues arising from discharge of effluents from sugar industry on to surrounding land or into a water body such as physicochemical properties of soil, changes in the micro flora, quantification of soil enzyme activities as influenced by effluents. Disposal of effluents without neutralization has become general practice. These effluents are chemically heterogeneous, contain organic and inorganic pollutants including, sugar baggage, molasses, carbonates, bicarbonates. The impact of sugar industry effluents on microbial activities in terrestrial ecosystem is scanty. There is also significant interest in the study of soil enzymes because such effect reflects the potential capacity of a soil to perform certain biological transformation of soil fertility.

Book Synopsis Enzyme Measurements Increases Understanding of Effects of Land Management by : Paul Igboji
Download or read book Enzyme Measurements Increases Understanding of Effects of Land Management written by Paul Igboji and published by Createspace Independent Publishing Platform. This book was released on 2016-07-31 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Enzymes show extraordinary specificity in catalysing biological reactions. A systematic classification of enzymes has been adopted on the recommendation of the International Enzyme Commission. The new system divides enzymes into six major classes, which are subdivided further into subclasses according to the type of reaction catalysed. For example a recommended name, a systematic name and a classification name for phosphodiesterase is phosphoric diester hydrolase while its classification number is EC 3.1.4. Research into soil enzymes has increased steadily over the last 30 years. Various activities associated with biotic and abiotic components contribute to the overall activity of soil enzymes. According to some scientists an enzyme may be associated physically with proliferating animal, microbial, and plant cells and it may be located in the cytoplasm in the periplasm of Gram-negative bacteria or attached to the outer surface of cells. They can also be present in non-proliferating cells (for example, microbial spores or protozoan cysts), in entirely dead cells or in cell debris. Other enzymes are present as an extracellular soluble molecule. They can also be temporarily associated in enzyme-substrate complexes, adsorbed to clay minerals or associated with humic colloids. Some of these categories according to experts may represent various stages in the life of an enzyme. An intracellular enzyme may still function after the cell dies and thus it becomes associated with cell debris. It may be released in the aqueous phase and may eventually be adsorbed in an active form by soil colloids. Enzyme-clay and enzyme-organic polymer complexes show remarkable resistance to proteolytic and thermal denaturation. Several methods exist for the measurement of enzyme activities. Experts cautioned about the interpretation of results arising from measurement of soil enzyme activities. According to these authors these measurements represent the maximum potential because the incubation conditions for enzymes assays are chosen to ensure optimum rates of catalysis. Thus the concentration of substrate is in excess and the optimum values of pH and temperature are selected to permit the highest rate of enzyme activity. Also the volume of the reaction mix is such that it allows free diffusion of substrate. Hence the problems arising from the interpretation of measured soil enzyme activity have often led to the conclusion that soil enzyme assays have no meaning in ecological and agricultural terms. Enzymes measurements do answer qualitative questions about specific metabolic processes, and in combination with other measurements (ATP, AEC, CO2 evolution), may increase the understanding of the effect of agrochemicals, cultivation practices, and environmental and climatic factors on the microbiological activity of soil. For example, some scientists discovered that enzyme activity was higher in the uppermost 20 cm of soil in plots tilled by shallow ploughing; this was not the situation in soils tilled by deep ploughing. This book explores in detail enzyme measurements as it affects understanding of land management practices.

Book Synopsis Dynamics of Redox Reactions Structure Decomposition and Greenhouse Gas Fluxes in Humid Tropical Forest Soils by : Steven James Hall
Download or read book Dynamics of Redox Reactions Structure Decomposition and Greenhouse Gas Fluxes in Humid Tropical Forest Soils written by Steven James Hall and published by . This book was released on 2013 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: Upland humid tropical forest soils experience fluctuations in oxygen (O2) availability and redox potential as a consequence of high rainfall, clay content, and respiration rates. Research in wetland ecosystems suggests that spatial and temporal variation in redox reactions strongly affect the biogeochemical cycling of carbon (C) and nitrogen (N). Here, I explored the impact of soil redox dynamics on decomposition and soil-atmosphere greenhouse gas fluxes in humid tropical ecosystems of the Luquillo Experimental Forest (LEF), Puerto Rico. Traditional theory and ecosystem models predict that elevated soil moisture leads to O2 limitation, constraining the enzymatic processes that mediate organic matter decomposition, and promoting the accumulation of soil C. Testing these hypotheses in upland humid tropical soils revealed the need for a more nuanced conceptual framework. In short: variation in moisture alone did not determine redox dynamics, hydrolytic enzymes activities persisted under reducing conditions, and redox fluctuations promoted decomposition on short (days) and long-term (decades) timescales. In Chapter One, I showed a relative decoupling between the temporal dynamics of soil moisture, soil redox reactions, and greenhouse gas fluxes over scales of days to weeks, using a field moisture manipulation experiment. Anaerobic biogeochemical processes such as iron (Fe) reduction and methanogenesis co-occurred in proximity to a well-aerated soil atmosphere and were little affected by fluctuations in soil moisture. Instead, redox reactions and gas fluxes appeared to vary constitutively according to differences in microtopography. In Chapter Two, I further explored relationships between reducing conditions and organic matter decomposition, by analyzing extracellular hydrolytic enzyme activities within and among sites differing in topography and rainfall. The enzymatic latch hypothesis proposes that reducing conditions inhibit hydrolytic enzymes via an accumulation of phenolic substances. I found little evidence for an enzymatic latch, and instead documented a strong positive relationship between reducing conditions, using reduced Fe (Fe(II)) as a proxy, and hydrolytic enzyme activities in a subset of sites. Furthermore, enzyme activities generally did not decline in an anaerobic incubation relative to aerobic controls. The assumption that reducing conditions constrain the decomposition activities of hydrolytic enzymes does not appear generally applicable in humid tropical forests. Next, in Chapter Three I examined the influence of temporal redox fluctuations on decomposition. Anaerobic conditions by definition limit the activity of oxidative enzymes, which require O2. The redox cycling of Fe, however, can potentially generate reactive oxygen species that mimic the function of oxidative enzymes. We demonstrated that concentrations of Fe(II) explained most of the variation in phenol oxidative activity within and among several sites in the LEF. Furthermore, Fe(II) oxidation stimulated short-term respiration, likely via a pH-mediated increase in dissolved organic C. Thus, stimulatory effects of redox fluctuations on oxidative decomposition processes might partially counteract short-term effects of O2 limitation. Finally, in Chapter Four I examined the overall impact of reducing conditions in comparison with other variables as they related to spatial patterns in soil C concentrations and turnover across the LEF. Soil C increased with Fe(II), an index of reducing conditions, but C tended to decline with increasing concentrations of reducible Fe oxides. Furthermore, the residence time of mineral-associated C (modeled using measurements of bomb radiocarbon) declined with Fe(II) concentrations. Together, the findings from these studies suggest a complex relationship between moisture, redox dynamics, and decomposition. First, short-term fluctuations in rainfall may have little overall impact on redox dynamics and the overall decomposition process, but longer-term differences in moisture among sites are associated with characteristic differences in redox reactions and greenhouse gas fluxes. Second, portions of the decomposition process mediated by hydrolytic enzymes appear resistant to periodic O2 deprivation and chronic reducing conditions, as well as the accumulation of phenolic substances. Third, redox cycling may give rise to important emergent mechanisms not evident under static aerobic conditions, mediated by coupled biotic and abiotic reactions with Fe oxides. Fourth, reducing conditions are associated with elevated soil C concentrations at the landscape scale, although the presence of reducible Fe oxides constrains C accumulation, and redox cycling might accelerate the turnover of mineral C over decadal scales. Together, these findings have implications for understanding the biogeochemical function of humid tropical soils, and their response to altered precipitation regimes and feedbacks to climate change. Two mechanisms thought to underlie the persistence of C in soils--reducing conditions induced by high soil moisture and the presence of reactive Fe minerals--may actually play unexpected roles in the decomposition of soil organic matter, a finding with potentially broad application across terrestrial and aquatic ecosystems.

Book Synopsis Plant, Soil and Microbes in Tropical Ecosystems by : Suresh Kumar Dubey
Download or read book Plant, Soil and Microbes in Tropical Ecosystems written by Suresh Kumar Dubey and published by Springer Nature. This book was released on 2021-09-25 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the multitude of interactions between plant, soil, and micro-organisms. It emphasizes on how growth and development in plants, starting from seed germination, is heavily influenced by the soil type. It describes the interactions established by plants with soil and inhabitant microbial community. The chapters describe how plants selectively promote certain microorganisms in the rhizospheric ecozone to derive multifarious benefits such as nutrient acquisition and protection from diseases. The diversity of these rhizospheric microbes and their interactions with plants largely depend on plant genotype, soils attributes, and several abiotic and biotic factors. Most of the studies concerned with plant–microbe interaction are focused on temperate regions, even though the tropical ecosystems are more diverse and need more attention. Therefore, it is crucial to understand how soil type and climatic conditions influence the plant–soil–microbes interaction in the tropics. Considering the significance of the subject, the present volume is designed to cover the most relevant aspects of rhizospheric microbial interactions in tropical ecosystems. Chapters include aspects related to the diversity of rhizospheric microbes, as well as modern tools and techniques to assess the rhizospheric microbiomes and their functional roles. The book also covers applications of rhizospheric microbes and evaluation of prospects improving agricultural practice and productivity through the use of microbiome technologies. This book will be extremely interesting to microbiologists, plant biologists, and ecologists.

Download or read book Biogeochemistry of Wetlands written by K. Ramesh Reddy and published by CRC Press. This book was released on 2022-09-10 with total page 926 pages. Available in PDF, EPUB and Kindle. Book excerpt: The globally important nature of wetland ecosystems has led to their increased protection and restoration as well as their use in engineered systems. Underpinning the beneficial functions of wetlands are a unique suite of physical, chemical, and biological processes that regulate elemental cycling in soils and the water column. This book provides an in-depth coverage of these wetland biogeochemical processes related to the cycling of macroelements including carbon, nitrogen, phosphorus, and sulfur, secondary and trace elements, and toxic organic compounds. In this synthesis, the authors combine more than 100 years of experience studying wetlands and biogeochemistry to look inside the black box of elemental transformations in wetland ecosystems. This new edition is updated throughout to include more topics and provide an integrated view of the coupled nature of biogeochemical cycles in wetland systems. The influence of the elemental cycles is discussed at a range of scales in the context of environmental change including climate, sea level rise, and water quality. Frequent examples of key methods and major case studies are also included to help the reader extend the basic theories for application in their own system. Some of the major topics discussed are: Flooded soil and sediment characteristics Aerobic-anaerobic interfaces Redox chemistry in flooded soil and sediment systems Anaerobic microbial metabolism Plant adaptations to reducing conditions Regulators of organic matter decomposition and accretion Major nutrient sources and sinks Greenhouse gas production and emission Elemental flux processes Remediation of contaminated soils and sediments Coupled C-N-P-S processes Consequences of environmental change in wetlands# The book provides the foundation for a basic understanding of key biogeochemical processes and its applications to solve real world problems. It is detailed, but also assists the reader with box inserts, artfully designed diagrams, and summary tables all supported by numerous current references. This book is an excellent resource for senior undergraduates and graduate students studying ecosystem biogeochemistry with a focus in wetlands and aquatic systems.
