Used in environmental research and agriculture to measure laccase enzyme activity in soil samples. This helps assess microbial activity and organic matter decomposition, which are key indicators of soil health. The kit enables detection of enzyme changes in response to pollutants, land use practices, or soil amendments, supporting studies on bioremediation, nutrient cycling, and sustainable farming. It is also applied in monitoring the impact of contaminants like heavy metals or pesticides on soil microbial functions.
