Environmental implications of stubble and their usages as soil and concrete reinforcement
Abstract: Stubble burning has been reckoned among the major contributors to air pollution, especially in North India. It is a significant source of gaseous pollutants causing serious damage to human health and the environment. The situation is more hazardous due to the intensive rice-wheat rotation system which generates a large amount of stubble with no significant use as good as burning due to poor knowledge of the management of stubble. It …
