    ASSESSMENT OF MACRO NUTRIENTS (N,P AND K) OF MONOCULTURE ,POLYCULTURE AND TERMITORIA SOILS IN POLLACHI , UDAMALPET TALUKS IN COIMBATORE AND TIRUPUR DISTRICTS ,TAMIL NADU , INDIA
    (Research Journal Of Chemistry And Environment, 2018) S, Kalaichelvi; N, Ezhili
    The objective of this research was to calculate the variation in pH and macro nutrients (N, P and K) of monoculture and polyculture soils compared with the termitoria soil from Pollachi and Udamalpet in Coimbatore and Tirupur Districts, Tamil Nadu, India during March 2013 to February 2014. The soil pH, N, P and K level are observed and compared in different soil samples. When compared to monoculture and polyculture soil, the termitoria soil pH, N, P and K favour agriculture and retain the plant nutrients. Through this study, we observed that termitoria soil pH and macronutrients are generally more than the monoculture and polyculture soils. Polyculture soil contains more nutrients when compared with monoculture soil. The study showed highly positive correlation between termitoria soil, monoculture and polyculture soils. The result highlights the value of termites and their beneficial role in soil and agriculture.

    ESTIMATION OF MICRONUTRIENTS AND HEAVY METALS OF MONOCULTURE, POLYCULTURE AND TERMITORIA SOILS (IN POLLACHI AND UDUMALPET TALUKS)
    (Int J Pharm Bio Sci, 2018) S, Kalaichelvi; N, Ezhili
    The aim of this research is to calculate the variation in micronutrients Manganese (Mn), Zinc (Zn), heavy metals Copper (Cu) and Iron (Fe) of monoculture and polyculture soils compared with the termitoria soil from Pollachi and Udumalpet in Coimbatore and Tirupur Districts, Tamil Nadu, India from March 2013 to February 2014. The level of Manganese and Zinc were determined based on the reaction of ions with an acidified molybdate reagent to yield a phophomolybdate complex. The concentrations of Cobalt and Iron were determined using Flame photometer, based on the method described in APHA. When compared to monoculture and polyculture soils, the termitoria soil increased the level of micronutrients was found, favours agriculture and retains the plant nutrients in the soil. In the same way the heavy metal concentration (Copper and Iron) level was also estimated. The result of heavy metals showed positive correlation with agriculture. Polyculture soil contains more nutrients when compared with monoculture soil. The study showed highly positive correlation between termitoria soil, monoculture and polyculture soils. The result highlights the value of termites and their beneficial role on soil and agriculture. The termitorium present in the monoculture and Polyculture land indirectly helps the agricultural soil to get improved with increased level of micronutrients and heavy metals through the chance of mixing mound soil by the wind, rain ect. It is right time for us to brand the terminology “termites are farmer’s friend”.

    ASSESSMENT OF PHYSICAL PROPERTIES OF MONOCULTURE, POLYCULTURE AND TERMITORIA SOILS IN POLLACHI, UDAMALPET TALUKS, COIMBATORE AND TIRUPUR DISTRICTS TAMIL NADU, INDIA
    (International Journal of Applied Environmental Sciences, 2017) S, Kalaichelvi; N, Ezhili
    The objective of this study was to determine the variation in physical properties of monoculture and polyculture soils compared with the termitoria soil from Pollachi, Udamalpet taluks, Coimbatore and Tirupur Districts, Tamil Nadu, India during March 2013 to February 2014.The Soil electrical conductivity (EC), Texture and particle size variation was observed in monoculture, polyculture and termitoria soils during the period. When compared to monoculture and polyculture soils the termitoria soil EC, Texture and particle size were favors agriculture and retain the plant nutrients. This study highlights that termite mound soil properties are generally more than the monoculture and polyculture soils. The study showed highly positive correlation between termitoria soil, monoculture and polyculture soils.

    ZOOPLANKTON DIVERSITY AND SEASONAL VARIATION OF THREE LAKES IN COIMBATORE, TAMIL NADU, INDIA
    (Journal of Academia and Industrial Research, 2016-08) R, Manikandan; S, Selvakumar; S, Kalaichelvi; N, Ezhili
    The present study was carried out to examine the diversity and density of zooplankton in Ukkadam Lake, Kuruchi Lake and Singanallur Lake in Coimbatore city, Tamil Nadu for the period of September 2012 to August 2013. The samples for Zooplankton analysis were collected early in the morning by plankton net of silk bolting cloth size of 25 µ and preserved in 4% formalin and glycerine for zooplankton analysis. During the present study period, a total 30 of genera of zooplankton composed of 8 genera of protozoa, 9 genera of Rotifer, in which 7 genera belonged to Cladocera and 6 to Copepoda were recorded in all the three lakes. Dominance of Rotifers indicated the eutrophic status of these studied lakes. Species diversity index for zooplankton population varied from 1.74 to 3.63. The zooplanktonic fauna of this lake were abundant during summer season while minimum numbers were recorded during rainy season. The present study findings clearly indicate intensified eutrophication of studied lakes.

    POTENTIAL ECOLOGICAL ASSESSMENT OF SEDIMENT QUALITY AND HEAVY METALS CONTAMINATION IN KURUCHI LAKE, TAMIL NADU, INDIA
    (J.Mater. Environ. Sci, 2014) R, Manikandan; S, Kalaichelvi; N, Ezhili
    Kuruchi Lake is an important freshwater body of Coimbatore City, Tamil Nadu, India. This lake receives municipal wastes and industrial effluents which contain heavy metals. Therefore, the present study was aimed to investigate the status of physicochemical properties and heavy metal levels in surface sediments of Kuruchi Lake. The result of physicochemical parameters such as pH, Electro Conductivity (EC), chloride, calcium, magnesium, phosphate, sulphate, sodium, potassium, total nitrogen, iron, total alkalinity and total organic carbon concentrations were found to be higher in sediment sample of station 4. The heavy metals concentration showed variations with Cd 4-14 mg/kg, Cr 2295-3198 mg/kg, Cu 872-1199 mg/kg, Ni 964-1520 mg/kg, Mn 4996-5820 mg/kg and Pb 999-1489 mg/kg, respectively. The highest concentrations of Cr, Pb, Ni and Cu were found to be higher in station 4, when compared to other study stations. Cd and Mn levels were found within the normal range. The cluster analysis was used for determining the similarity of heavy metals concentrations in different study stations. This study reveals that sediments of Kuruchi Lake were partially polluted with heavy metals. This study provides the baseline data for future sediment quality assessment of this lake and regular monitoring of sediment quality in this lake is highly recommended.
