Abstract

Burning of surplus sugarcane trash for land clearing is a common practice followed by the farmers. The ashes generated from sugarcane trash burning will results in change in the physico-chemical properties of soils due to their alkaline nature. Ashes, due to presence of unburnt carbon, have exhibited potential to adsorb pesticides; therefore, might affect degradation, leaching and sorption of pesticides. Atrazine (Atz) and fipronil are commonly used pesticides in sugarcane. Due to their extensive application and their potential eco-toxicological effects, the global scientific interest focusing on the research of the environmental fate and behavior of pesticides after their entrance in the environmental matrices is undiminished. A comprehensive review on the effect of sugarcane trash ash on the sorption, degradation and leaching of atrazine (Atz) and fipronil in agricultural soils is so far not available. The objective of this review is thus to systematically summarize the impact of sugarcane trash ash on fate of atrazine (Atz) and fipronil in agricultural soils. Notably, the mechanisms and factors influencing were also extensively elucidated. This review helps better understand the effects of sugarcane trash ash on sorption, leaching, and degradation of atrazine (Atz) and fipronil in agricultural soils.
