Solar distillation is very much effective for availing drinkable pot water, especially in desert areas and salt-producing areas. A Still a device that can be used to convert impure (saline) water into fresh drinking using the process of Distillation. The energy source sunlight thus it uses renewable energy. This paper describes set equations find distillate yield solar still by taking input par...

Moss crusts play important roles in biological soil crusts biomass and soil surface stabilization. However, because of increasingly intensive human activities, especially grazing, the growth and survival of shrubs are seriously threatened. This study aimed to test whether the presence of shrubs affects the physiological state of the bryophyte Syntrichia caninervis Mitt. in this desert ecosystem...

Mycorrhizal technology was applied for reclamation of saline wasteland of Indian Thar Desert. For this purpose an exotic tree species Acacia colie an endemic legume of Australia was selected. Studies revealed increased biomass production and nutrient uptake of Acacia collie by native AM fungi. Different AM fungi showed their variation towards response to this tree species. However, AM fungi res...
