Interactive Simulation of Fire, Burn and Decomposition. (December 2007) Zeki Melek, B.S., Bogazici University; M.S., Bogazici University Chair of Advisory Committee: Dr. John Keyser This work presents an approach to effectively integrate into one unified modular fire simulation framework the major processes related to fire, namely: a burning process, chemical combustion, heat distribution, deco...

The rice–wheat cropping system is the main food bowl in Asia, feeding billions across globe. However, productivity and long-term sustainability of this are threatened by stagnant crop yields greenhouse gas emissions from flooded rice production. negative environmental consequences excessive nitrogen fertilizer use further exacerbating situation, along with high labor water requirements transpla...

containing about 1.90 million Mg of nutrients, are available in the IGP of India (Sarkar et al., 1999). In the Rice (Oryza sativa L.)–wheat (Triticum aestivum L.) farmers in Indian Punjab alone, about 12 million Mg of rice straw India burn or remove residues to facilitate seedbed preparation. Incorare burned annually, which causes about 0.7 million Mg poration of residues before planting of the...

ABSTRACT: Crop residues decomposition are controlled by chemical tissue components. This study evaluated changes on plant components, separated the Van Soest partitioning method, during cover crop decomposition. The soluble fraction was first to be released from residues, followed cellulose and hemicellulose. Lignin residue component that suffered least degradation, for certain types, lignin de...

abstract in order to evaluate the effects of rice conventional herbicides on rotational second crops (lettuce, cress, clover, canola and radish), soil microbial biomass and diversity, a field and glasshouse experiments were conducted in mazandaran province and research glasshouse of ferdowsi university of mashhad, respectively. five experiments were carried out for 5 second crop separately with...

Calcium hydroxide was petitioned for use as a soil amendment to supply calcium for crops. Calcium hydroxide (also known as hydrated lime) is produced from the slow addition of water to crushed or ground quicklime (calcium oxide), which is produced by burning various forms of limestone. It may also be produced as a by-product of industrial processes such as from the generation of acetylene from ...

Biomass based energy generation is one of the major focus areas of renewable energy programs in India. The strength of India’s biomass resources mostly lies in the agricultural sector. A large quantity of crop residue biomass is generated in India. However, crop residue biomasses are distributed resources with variation in spatio-temporal availability and its characteristics. Competing uses of ...
