Abstract - The increasing use of chemical fertilizers and pesticides for agricultural production is causing soil pollution. The objective of this study was to investigate the soil nutrient analysis and pesticides residues in soil samples from Kodaikanal, where the fruit and vegetables are cultivated more. There has been an increasing concern about food quality and safety of agricultural products obtained from contaminated sites. The bioavailability of nutrients in the soil may bring to a close growth and productivity of crops. The soil samples were collected from different places of cultivated land particularly carrot field in Vilpatti, Pallangi, Mannavanur, Poomparai and Pazhamputhur were selected. Nitrogen content showed 84%, whereas Phosphorous 5.5% and Potassium 120%. NPK level as well as Zn, Fe, Mn, Cu nutrients were showed sufficient amount except nitrogen content. GCMS was done for the analysis of pesticides residues in the cultivated soil. No pesticide residues were found in the cultivated soil. The nutrient analysis of Carrot (Daucas carota) were analyzed and the result showed that rich in protein, carbohydrate, fibre, ash and further FTIR analysis was performed to know the functional groups on vegetables.
extremely insoluble in the soil solution. This insolubility is due to the affinity of P to cations such as Ca2+, Mg2+ and Al3+, and its ready adaptation into organic forms that are not amenable to plant uptake(8). Micronutrients, such as Fe, those are required in small concentrations for plant growth can become very restrictive elements. (2).The present study is carried out by evaluating the soil fertility in eight places of kodaikanal and crops nutrient content. 2. MATERIALS AND METHODS 2.1 Collection of Soil samples: Soils under carrot cultivation from four different sites (agricultural fields) of Dindigual district of Tamil Random sampling method was adopted for soil collection. Soil was collected from 5–6 different sites of each agricultural field by digging soil to depth of 15–20 cm. The samples were brought to laboratory, dried at room temperature for 72 h and finally ground into fine powder. The soil nutrient analysis and Pesticide residues was analysed using GC-MS in Tamil Nadu Agriculture University, Coimbatore.

1. INTRODUCTION
The Fresh vegetables of carrot were collected from agriculture land of Kodaikanal and were powder
Soil nutrients are critical elements for plant growth and efficient productivity. Soil contains mixtures of minerals, organic matters which supports the plant growth they differs from the parent material in the morphological, physical, chemical and biological properties.(3) The bioavailability of nutrients in the soil solution may determine plant growth and existing nutrient grade of the plant ( Hillette Hailu). Plant sustains large microbial population in rhizosphere by secreting substance like carbohydrate and aminoacids through root cells.
were subjected to the qualitative phytochemical and FTIR analysis. 3. RESULTS AND DISCUSSION Soil acts as an important part of all terrestrial systems, providing habitat for micro-organisms, plants, and animals. The soil characteristics and the amount of macro and micronutrients values were presented in the Table1. Nitrogen content in soil was low compared to other Phosphorous and Potassium. Today, an increase in the
The most common form of N fertilizer is highly soluble in the soil solution and can be easily lost by leaching or by bacterial de nitrification. P is the second most essential factor in determining plant productivity because the anionic form of phosphate, in which P is assimilated by plants, is
