| Abstract | Production of switchgrass as a dedicated energy crop in the USA was proposed as a way to produce valuable products on millions of hectares that had been bid from traditional crop production by a variety of federal programs. The objective of the present study is to determine the expected economic consequences in terms of cost to deliver biomass feedstock, from restricting switchgrass production to marginal land for a case study region, when (a) land use is restricted to class IV; (b) land use is restricted to classes III and IV; and (c) use of land capability classes I, II, III, and IV is permitted. A hypothetical biorefinery with a processing capacity of 2000 Mg/day is assumed with switchgrass as the single biomass source. Soils and weather data were used in combination with crop management data to simulate switchgrass yields for each land capability class, for 50 years, for each of 30 Oklahoma counties. Land opportunity cost required to bid land from current use for each land capability class and each county were simulated based on the 2013 revealed county average Conservation Reserve Program (CRP) rental rates adjusted across capability class by relative productivity. A mathematical programming model was constructed and solved to determine the optimal quantity, location, and quality of the land leased. For the case study region, restricting land use to only capability class IV increases the land requirement by 44 % and increases the cost to deliver feedstock by 32 % compared to when switchgrass production is permitted on land classes I–IV. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
