Soil physicochemical and biological properties of restored rock phosphate mined area of Maldeota in Doon valley were studied to evaluate the impact of fire. The soil texture of Maldeota varies from sandy loam to loamy sand. Soil organic carbon and soil microbial biomass was studied in a natural forest area and in a restored mined area at Maldeota. Soils samples were collected from both fire affected and unaffected sites. The objective of the present study was to evince the changes in soil properties after fire. Microbial biomass carbon in the burnt restored area found to be greater as compared to that of natural area. Soil moisture content and soil microbial quotient reveals that natural forest has good soil quality whereas the rest of the sites are devoid of good microbial quotient and moisture content. The Microbial Biomass Carbon (MBC) and soil organic carbon together can be considered more effective in estimating the reclamation efforts.
Artemisia annua L. belonging to the family Asteraceae, is a fragrant annual herb. The genus Artemisia contains more than 400 species, and distributed mainly in the Northern Hemisphere, especially in Asia, Europe and North America (Pellicer et al., 2006; Nibret & Wink 2010). This genus is represented by 32 species in India (Hajra et al., 1995). Many species of the genus Artemisia are used in the folk and traditional medicine and also used as spices, and for alcoholic drinks (Baser & Buchbauer 2010). Plant commonly named Sweet Annie, Sweet Wormwood Annie, Sweet Sagewort, Annual Wormwood or Qinghaosu. In Uttarakhand commonly known as "Paanti". In Chinese traditional medicine use of this plant was recorded before 168 BC.In 1972, artemisinin the active crystalline constituent was isolated from the aerial portions of the plant. Artemisinin is a sesquiterpene lactone which have antimalarial properties (Klayman, 1985). It is the only
