Three stands viz. pure sal, plantation and\u00a0mixed were considered as treatment of the study. A quadrate sample plot of 10\u00d710\u00a0m2 size was measured to collect soil samples for both chemical analysis and fungi\u00a0isolation. Soil pH, electrical conductivity, organic matter content, total N, available P,\u00a0exchangeable K, available S, fungal abundance and colony character (cm) were\u00a0determined to achieve the objective of the study. The results revealed that soil pH\u00a0and electrical conductivity were highest (6.61 and 21.10\u03bcS\/cm) in mixed stand and\u00a0lowest (6.38 and 10.75\u03bcS\/cm) in pure stand. Organic matter content and total N\u00a0were highest (2.24 and 0.145%) in plantation stand and lowest (1.65 and 0.112%) in\u00a0mixed and pure stand, respectively. Available P, exchangeable K and available S were\u00a0highest (3.65, 98.66 and 17.53ppm) in pure stand and lowest (1.97, 79.49 and\u00a010.25ppm) in plantation stand. In addition, four fungal genera Sclerotium,\u00a0Rhizoctonia, Pythium and Verticillium were identified in the study area soils. The\u00a0highest fungal population (entire genus except Verticillium) (colony number\/g soil)\u00a0was found in mixed stand while it was found lowest in pure (Sclerotium ) and\u00a0plantation stand (Rhizoctonia and Pythium ). There was no significant variation in\u00a0colony diameter of the fungi among the treatments. Therefore, it can be concluded\u00a0that better soil health was maintained in natural forest rather than plantation forest.<\/p>\n<p style=\"text-align: justify;\"><strong>Key words:\u00a0<\/strong>Soil health,\u00a0Sal forests,\u00a0Chemical properties,\u00a0Fungi<\/p>\n<p style=\"text-align: justify;\">DOI: <a id=\"pub-id::doi\" href=\"http:\/\/dx.doi.org\/10.3329\/ralf.v2i1.23025\">http:\/\/dx.doi.org\/10.3329\/ralf.v2i1.23025<\/a><\/p>\n<p style=\"text-align: justify;\"><strong>[\/showhide]<\/strong><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #800000;\"><strong><a style=\"color: #800000;\" href=\"http:\/\/agroaid-bd.org\/ralf\/wp-content\/uploads\/sites\/2\/2015\/04\/ag-3.pdf\">Download Full Article PDF<\/a><\/strong><\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Author: Mohammad Kamrul Hasan and Md.
