Phosphatase
Phosphorus is an essential nutrient. In spite of its wide distribution in nature, P is a limited resource (Shimamura et al., 2003) and it is deficient in most soils (Vassilev et al., 2001). Extracellular phosphatases are of interest for their role in mineralizing P. Studies indicate that high enzyme activity signals element limitation in the ecosystem (Ndakidemi, 2006). Soil acid phosphatases constitute an important link between biologically unavailable and bioavailable P pools in the soil (Speir and Ross, 1978). Apart from being good indicators of soil fertility, phosphatase enzymes play key roles in the soil system (Dick and Tabatai, 1992; Dick et al., 2000). The strong inhibition activities of a variety of enzymes have been reported in metal polluted soils over the past years (Huang and Shindo, 2000). However, little is known about the phosphomonoesterase activities and soil quality in significant locations of Vellore. The aim is to know the distribution of heavy metals and phosphomonoesterase activity in various locations of Vellore and to assess soil quality based on these soil parameters. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Revised Text: Phosphorus is an essential nutrient. In spite of its wide distribution in nature, P is a limited resource (Shimamura, et al., 2003) and is deficient in most soils (Vassilev, et al., 2001). Extracellular phosphatases are of interest for their role in mineralizing P. Studies indicate that high enzyme activity signals element limitation in the ecosystem (Ndakidemi, 2006). Soil acid phosphatases constitute an important link between biologically unavailable and bio-available P pools in the soil (Speir and Ross, 1978). Apart from being good indicators of soil fertility, phosphatase enzymes play key roles in the soil system (Dick and Tabatai, 1992; Dick, et al., 2000). The strong inhibition activities of a variety of enzymes have been reported in metal polluted soils over the years (Huang and Shindo, 2000), however little is known about the phosphomonoesterase activities and soil quality of significant locations in Vellore. Our aim is to document the distribution of heavy metals and phosphomonoesterase activity at various locations in Vellore, and to assess soil quality based on these soil parameters. Editor: 1.
