Most of the area of Pakistan is arid and semi-arid where artificial means of irrigation area also not available due to different reason. It is, therefore, not feasible to grow agricultural crops or even trees with ordinary efforts and techniques. Trees have great importance in these areas keeping in view their climatic conditions. One of these is to use chemicals to retain the available moisture for longer time and make it available to plants in their tender age. An experiment was laid out at Maujghar in Cholistan to study the effectiveness of such a chemical 'alkasorb' for its water retaining capacity and its ultimate effect on the survival and growth of tree species.
