Spread in 72 experiments the analyses of soil, water and air have been described in a simple manner so that most of these experiments can be conducted even by the beginners in this subject. The principals involved, preparation of the reagents and the procedures are described for each experimental method. The authors hope that this manual would prove to be useful in laboratories where soil, water and air are routinely tested. aTable of Contentents: PART I - WATER ANALYSIS : Principles of Spectrometric Analysis Sampling Techniques Colour Turbidity Total Dissolved Solids Conductance pH Value Acidity Alkalinity Dissolved Oxygen Chemical Oxygen Demand Biochemical Oxygen Demand Dissolved Organic Carbon Calcium Hardness of Water Total Hardness of Water Nitrate Nitrogen Nitrate Nitrogen Brucine Method Ammonia Nitrogen Fluoride Fluoride in Drinking Water (by Fluoride Electrode) Chloride Residual Chlorine Sulphide Sulphite Sulphate Phosphate Iron Chromium Copper Lead Nickel Cadmium Mercury Cyanides Boron Selenium Arsenic Suspended Solids Determination of Chlorophyll-a Determination of Productivity PART II SOIL ANALYSIS : Collection of Soil Samples pH Value Soluble Salts Identification of Calcium Carbonate, Nitrogen, Phosphorus and Potassium Calcium Carbonate Gypsum Requirement Lime Requirement Alkalinity Organic Carbon Total Nitrogen Available Nitrogen Ammonium Nitrogen Nitrate Nitrogen Nitrite Nitrogen Available Phosphorus Available Sulphur Silica Available Potassium Sodium Calcium and Magnesium Micronutrient Elements Pesticide Residues Separation and Identification of Pesticide Residues from the Soil PART III AIR ANALYSIS : Qualitative Analysis of CO, CO2, H2S, SO2, NO and NO2 Carbon Monoxide Carbon Dioxide Hydrogen Sulphide Sulphur Dioxide Nitric Oxide and Nitrogen Dioxide Particulates PART IV MISCELLANEOUS: Calcium in Egg Shells Effect of pH on Germination of Seeds Effect of Copper Salt on Germination of seeds Phosphate in Detergents Benzoic Acid and Sorbic Acid in Soft Drinks Sulphur Dioxide in Soft Drinks Identification of Food Adulterants Appendices References Index aWater Analysis973140 aSoil Analysis973141 aAir Analysis973142 aGOPALAN (R)973143 aANAND (Amritha)973144 aSUGUMAR (R Wilfred)973145 2ddccBK c226807d226807 00102ddc40708FPTaALbALd2023-02-23eBiblios Book Point Surathkal Mangalore 575014g252.00l0o574.5028 GOPLp076419r2023-02-24 00:00:00v315.00w2023-02-24yBK
