the stady and analysis of rice agroclimatology in lenjan
the west of esfahan province, iran, is one of the most important agricultural areas throughout the country due to the climate variability and life-giving water of zayanderood river. rice is one of the major and economic crops in this area. the most important climatic elements in agricultural activities which should be considered include temperature, relative humidity, precipitation and wind. so...
15 صفحه اولinvestigation of chemical pretreatment of rice straw with ammonia, urea and sodium hydroxide
agricultural residues have high potential to produce biogas, but they contain lignocellulosicmaterials which are not easily degradable, so the pretreatment is required. chemical pretreatmentincreases the rate of degradation and efficiency of biogas production. this study has beeninvestigated the effect of 4% -urea, 5%-ammonia and 8%-sodium hydroxide on degradation of ricestraw and production of...
متن کاملImpact of 15N-labeled rice straw and rice straw compost application on N mineralization and N uptake by rice
Incorporation of plant residues in soil affects N and C content and dynamics. This studydetermined the effects of short-term alternative rice (Oryza sativa L.) residue management on Nmineralization and uptake by rice. Pot and laboratory incubation experiments were established byincorporating 15N-labeled rice straw and rice straw compost in paddy soil. The 15N recovered by riceaveraged 16.6%; mo...
متن کاملUtilization of Urea and Urease Treated Rice Straw by Indigenous Growing Cattle
The experiment was conducted to study the effect of treatment of rice straw with urea and a urease containing midden soil on the chemical composition of treated rice straw, feed intake of the animals, nutrients digestibility, body weight gain, feed conversion efficiency and overall economy of feeding for a period of 105 days. Twelve indigenous growing cattle (live weight 130.00±1.67 kg) were se...
متن کاملPretreatment of rice straw with combined process using dilute sulfuric acid and aqueous ammonia
BACKGROUND Use of lignocellulosic biomass has received attention lately because it can be converted into various versatile chemical compounds by biological processes. In this study, a two-step pretreatment with dilute sulfuric acid and aqueous ammonia was performed efficiently on rice straw to obtain fermentable sugar. The soaking in aqueous ammonia process was also optimized by a statistical m...
