| Abstract | The impact of soil available water content (AWC) on the growth and foliar nutrient concentrations of trees in 7-yr-old hybrid aspen (Populus tremula L. x P. tremuloides Michx.) plantations established on abandoned agricultural lands was studied. AWC in the topmost 75 cm soil layer was significantly related to height growth and foliar N concentration of hybrid aspens. The correlations were stronger on well-drained automorphic soils and in the case of a dry growing season with insufficient precipitation. AWC over 150–160 mm can be considered sufficient, and below 120 mm insufficient for fast growth of hybrid aspen. The differences in AWC were less pronounced in the top 25 cm soil layer but were more noticeable in the 25–50 and 50–75 cm soil layers. AWC estimated as a function of soil specific surface area and bulk density was shown here to be a significant indicator for site selection for establishing hybrid aspen plantations. Foliar N concentration over 2.7% can be considered optimal and below 2.4%, insufficient for hybrid aspen on the studied soils. Foliar concentrations of P (on average 0.24%) and K (on average 0.79%) varied little and, thus, did not correlate with tree growth. The most suitable previous agricultural soils for afforestation with hybrid aspen would be moderately drained Albeluvisols, Luvisols and Planosols. |

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.
