Soil is crucial to life on earth. Enormous agriculture practices may emerge a numerous problem like reduction in soil fertility, erosion, ground water contamination which has direct impact on the soil health. It is indispensable to study overall microbial activity potential and different changes in soil biological properties for maintaining soil health and its quality. Soil enzyme is essential to play important role in maintaining soil health and to asses it quality. The fluorescein diacetate (FDA) hydrolysis is one of the important to measures the enzyme activity of microbial populations and can provide an assessment of microbial activity in soil. Assessment of Hydrolysis of fluorescein diacetate [3′, 6′-diacetylfluorescein (FDA)] has been suggested as prospective method for determination of total microbial activity because it includes several enzyme classes including lipases, esterases, and proteases. Spectrophotometric determination of the hydrolysis of fluorescein diacetate (FDA) was shown to be a simple, sensitive, and rapid method for determining microbial activity in soil. The assessment of FDA in soil is done by incubating the soil sample with buffer and FDA for 1 – 2 hours. The amount of fluorescent color formation during the incubation is indicative of the enzymatic activity of the microbial community in the sample. The intensity of the color will be measured by a spectrophotometer and compared to a standard curve to determine the relative microbial activity in your sample. The main intendment of this review paper to define the role of FDA hydrolysis in soil environment as well as method to estimate FDA enzyme activity in soil. Paper also illustrate that FDA enzyme activity serves as microbial indicator and measure of total microbial activity to asses soil health and is quality.
