Carbon dioxide emission from soil grown to wheat crop at Khumaltar, Lalitpur / S Kandel    

Public ISBD in Proceedings of the Second National Soil Fertility Research Workshop, 24-25 March, 2015. Soil Science Division, NARC, Khumaltar, Lalitpur, Nepal / Krishna B. Karki     Title : Carbon dioxide emission from soil grown to wheat crop at Khumaltar, Lalitpur Material Type: printed text Authors: S Kandel, Author ; S.C Shah, Author ; Gautam, A.K., Author ; K.R Pande, Author Pagination: 412-420 p. Languages : English (eng) Keywords: Carbon  dynamics,CO2  emission,  mulching,  zero  tillage. Abstract: Changes in farming practices could be an effective way to reduce carbon (CO2-C) emissions from agricultural lands thereby sequestering more carbon in the soil. A field experiment was conducted on an acidic silt loam upland soil of Khumaltar, Nepal during the dry season of 2011/2012. The study evaluated soil CO2 - C emission from a wheat field as influenced by tillage, mulch, and nitrogen (N) application. The factorial experiment laid-out on  a split-split plot design consisted of three replications of 12 treatment combinations, i.e., two types of tillage (zero and conventional) on a main-plot, two levels of mulch (zero and 4 t ha-1 of rice straw) on a sub-plot and three levels of N application (zero, 100 and 150 kg ha-1) on a sub-sub plot. The crop growing season in this region is relatively longer  primarily due to  the effects  of low temperature and high elevation (1300 masl); therefore, wheat (var. WK-1204) planted on December 6 of 2011 matured in six months (harvest date June 2 of 2012)………………..

Graham’s Colorimetry as an estimate of Soil Organic Carbon in Chitwan Valley Soils, Nepal / R Ghimire    

Public ISBD in Agricultural research for poverty alleviation and livelihood enhancement. Proceedings of the 3rd SAS-N Convention 27-29 August 2008, Lalitpur / Paudyal, Krishna Prasad     Title : Graham’s Colorimetry as an estimate of Soil Organic Carbon in Chitwan Valley Soils, Nepal Material Type: printed text Authors: R Ghimire, Author ; S.C Shah, Author ; K.R Dahal, Author ; J.G Lauren, Author ; Adhikari, C., Author Pagination: 405-409 p. Languages : English (eng) Keywords: Colorimetric  method,  dry  combustion,  soil  organic  matters,  texture Abstract: Soil organic carbon (SOC) influences soil physical and chemical processes, and serves as repository source of plant nutrients. Limited information is available concerning SOC status of different layers in Nepalese soils. Two hundred soil samples from five different soil depths (0-5, 5-10, 10-15, 15-30 and 30-50 cm) of Rampur and Baireni, were analyzed to evaluate the precision of Graham’s colorimetric method of SOC analysis. The SOC values obtained from Graham’s colorimetric method were compared with dry combustion SOC values for the same soil samples……………… Link for e-copy: http://elibrary.narc.gov.np/?r=1562 in Agricultural research for poverty alleviation and livelihood enhancement.
