This study examines the effects of straw management and winter flooding on soil N dynamics and crop N uptake in California rice (Oryza sativa L.) systems. Experiments were established in two locations in northern California with main plot treatments being winter flooding or no flooding; and four straw management practices (burn, remove, incorporate, and roll) as subplot treatments. Fertilizer w...

The draft genome sequence of Geobacillus sp. strain 1017, a thermophilic aerobic oil-oxidizing bacterium isolated from formation water of the Dagang high-temperature oilfield, China, is presented here. The genome comprised 3.6 Mbp, with the G + C content of 51.74%. The strain had a number of genes responsible for numerous metabolic and transport systems, exopolysaccharide biosynthesis, and deco...

Aerobic composting is widely used worldwide as a natural process for handling human waste. Such waste often contains pharmaceutical residues from consumption, yet their impact on has not been studied. The aim of this study to investigate the antihistamine cimetidine (10 mg/kg, 100 mg/kg) aerobic feces. key results show that 10 mg/kg accelerates temperature increase and moisture removal substrat...

in this paper, we use modified laplace decomposition method to solving initial value problems (ivp) of the second order ordinary differential equations. theproposed method can be applied to linear and nonlinearproblems

11 Peatland ecosystems accumulate thick organic soil layers because plant production exceeds decomposition throughout the entire organic soil column (Fig. 1). Peatlands cover only about 2–3% of the Earth’s land surface but store around 25% of the world’s soil carbon1. They are most abundant at northern high latitudes (Fig. 2a), where they cover roughly 4,000,000 km2 of land1 and store an estima...

Abstract Peat swamp forest is an important ecosystem in global climate change through its high carbon content and role as a sink. In peat forest, there near-closed cycle of nutrients including carbon. order to better understand the rate plant litter production decomposition, study was carried out three secondary forests Central Kalimantan, Indonesia. Litterfall collection undertaken using trap ...
