Bioenergy related land use change would likely alter biogeochemical cycles and global greenhouse gas budgets. Energy cane (Saccharum officinarum L.) is a sugarcane variety and an emerging biofuel feedstock for cellulosic bio-ethanol production. It has potential for high yields and can be grown on marginal land, which minimizes competition with grain and vegetable production. The DayCent biogeoc...

Abstract Background Peatlands form one of the largest carbon pools in terrestrial ecosystems, representing approximately one-third world’s soil carbon. The aim this study was to evaluate C:N:P stoichiometry as an indicator changes initialized by dehydration Histosols varied origins. Four types from lowland and mountain areas were investigated: fibric Histosols, hemic sapric drainic. Results We ...

The addition of organic byproducts to soils is a vital source essential nutrients for plant uptake. To reuse the effectively, there need estimate release patterns from byproducts. This study aimed investigate [nitrogen (N), phosphorus (P), and potassium (K)] bagasse, sugarcane milling byproduct, at two soil depths (surface 0 cm vs. buried 15 cm) in fallow fields on types (Histosols Spodosols) F...

Peatlands are a subset of wetlands that have accumulated significant amounts of soil organic matter. Soils of peatlands are colloquially known as peat, with mucks referring to peats that are decomposed to the point that the original plant remains are altered beyond recognition (Chapter 6, SSSA 2008). Generally, soils with a surface organic layer >40 cm thick have been classified as Histosols in...

a mineral soil (Farnham and Finney, 1965), which provides a high potential for diffusion and storage of O2 Organic soils in the Everglades Agricultural Area (EAA) of southfor microbial utilization in the organic soil. Neller (1943) ern Florida, USA, are subsiding due primarily to oxidation by aerobic microorganisms. Since there are large C losses in drained Histosols, reported that soil O2 rang...

Subsidence of the Everglades Histosols occurs at a rate of approximately 3 cm/year. The major cause of this loss of soil is the oxidation of the organic matter by the microbial community. One of the products of this microbial activity is inorganic nitrogen. Assuming an annual subsidence rate of 3 cm, approximately 1400 kg/ha of nitrogen is released per year. Much of this nitrogen accumulates in...

Soil microbes play critical roles in regulating terrestrial carbon (C) cycle and its feedback to climate change. However, it is still unclear how the soil microbial community and abundance respond to future climate change scenarios. In this meta-analysis, we synthesized the responses of microbial community and abundance to experimental warming from 64 published field studies. Our results showed...
