Impact 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...

straw burned (Bird et al., 2001; 2002). Recent work in tropical and temperate rice ecosystems has determined The transition from open-field burning of straw residues to alternathat the operationally-defined mobile humic fraction tive residue management practices may affect soil C sequestration potential and the supply of nutrients to crops. A field study of dual(Na4P2O7 or NaOH extractable) is ...
متن کاملNitrogen Dynamics in the Rumen and Abomasum of Sheep Determined with 15n-labelled Ammonia Or
An experiment was carried out to investigate the dynamics of nitrogen (N) in the rumen and abomasum of rumen and abomasum-cannulated sheep using 15N dilution techniques. The 15N tracer was administered into the rumen as 15N-ammonia or 15N-labelled duckweed and the transfer of the 15N label to various N pools was followed. Flow of digesta from the rumen into the abomasum was ascertained by doubl...

15 صفحه اولthe study of bright and surface discrete cavity solitons dynamics in saturable nonlinear media
امروزه سالیتون ها بعنوان امواج جایگزیده ای که تحت شرایط خاص بدون تغییر شکل در محیط منتشر می-شوند، زمینه مطالعات گسترده ای در حوزه اپتیک غیرخطی هستند. در این راستا توجه به پدیده پراش گسسته، که بعنوان عامل پهن شدگی باریکه نوری در آرایه ای از موجبرهای جفت شده، ظاهر می گردد، ضروری است، زیرا سالیتون های گسسته از خنثی شدن پراش گسسته در این سیستم ها بوسیله عوامل غیرخطی بوجود می آیند. گسستگی سیستم عامل...
