This review discusses the differences between composting and vermicomposting of biodegradable solid waste. Solid waste management is a major challenge worldwide due to the rise in population and industrialization, leading to larger amount of solid wastes being generated. Biological process has been widely recognized in converting solid organic materials into environmental friendly and value add...

Soil organic carbon (SOC) sequestration through the application of amendments (OAs) is considered an important strategy to offset anthropogenic CO2 emissions while simultaneously enhancing soil quality and food security. The efficiency SOC sequestration, however, depends on priming effect which influenced by interactions OA composition with microbial response variables (MRVs). Yet, there remain...

A wide array of organic chemicals occur in biosolids and other residuals recycled to land. The extent of our knowledge about the chemicals and the impact on recycling programs varies from high to very low. Two significant challenges in regulating these materials are to accurately determine the concentrations of the organic compounds in residuals and to appropriately estimate the risk that the c...

The enormous use of chemical fertilizers recently has contributed to negative impacts on soil quality for agriculture purposes. However, if we the fertilizer along with organic amendment, it would offer a good approach sustainable practice. Therefore, this study examined effects HT Organic Compound (HTOC) application heavy metal and macronutrient content in 2-season cultivated paddy field from ...

During the past dozen years the original meaning of the Eleventh Amendment has become a matter of active controversy, both among legal scholars and among the justices of the Supreme Court.' Modern Eleventh Amendment doctrine remains governed by the traditional view, which in gross outline holds that the amendment is a jurisdictional bar prohibiting the federal courts from hearing unconsented su...

this work investigates the effect of the application rate and type of sludge throughout the soilcarbon cycle in a semiarid mediterranean agro-ecosystem. we study the two-year evolution of the variouspools of soil organic and inorganic carbon and their influence on soil respiration. we applied three rates (40, 80 and 160 mg/ha) of two types of sludge –aerobically and anaerobically digested sewag...

Incorporation of biochar to agriculture field has the potential to be a primary factor in maintaining soil fertility and productivity particularly in nitrogen and organic matter limiting environments however, clear experimental evidence to support this views still lacking. The current experiments were carried out to evaluate the effect of different organic (biochar and FYM) and inorganic amendm...

The Po river plain lowland springs represent unique paradigms of managed environments. Their current locations used to be swamps that were drained 6-7 centuries ago, and they have been in constant use ever since. Our aims were to identify the effects of land use on the microbial communities of these soils, look for associated diversity drivers, and assess the applicability of ecology theories w...
