Book Description
The book manual of soil Plant and water analysis is essential for agricultural and horticultural courses in Colleges and Universities. Also it finds its importance in Fisheries (for pond soil) Sericulture (for mulberry cultivation) and Animal Sciences (for fodder cultivation). Explanations, descriptions, procedures and calculations of results are arranged systematically in easy language so that this guide can be used by laboratory personnel with a wide range of education level. Also basic values and factors needed for calculating results are given in each method so that no extra books and tables are normally required although some exceptions could not be avoided. The book is suitable to establish a Soil, plant and water testing laboratory and / or test the soil, plant and water. The basic purpose here is to help in making the fertilizer recommendations for Optimum production Contents Chapter 1: Soil Testing and Fertility Management 1-21; Definition, Objectives, Importance and facilities, Methods of soil fertility evaluation; Microbial test for determining soil fertility: Azotobacter plaque test, Aspergillus niger test, Cunninghamella plaque method; Chemical methods for evaluating Soil fertility: Qualitative test, Rapid plant tissue tests; Quantitative test, Vegetative methods, Visual diagnosis of deficiency symptoms, Use of indicator plants; Phace of Soil testing; Instrument Used, Sampling procedure, Dispatch, Sample preparation, Analysis, Soil texture, Electrical conductivity, pH, Calcariousness, Organic carbon, Available nitrogen, Available phosphorus, Available postassium, Available secondary nutrients, Lime requirement, Gypsum requirement; Interpretation and fertilizer recommendations; Chapter 2: Methods of Soil Analysis; Determination of available nutrients; Determination of organic carbon; Titrimetric method, Colorimetric method; Determination of available nitrogen; Alkaline potassium permanganate method, Calcium hydroxide method, Calcium hydroxide method, Incubation method( Kenny and Bremrer, 1962), Nitrate-N by pheno Disulphonic acid method, Ammonium-N by colorimetric method; Determination of available phosphorus; Olsen s method, Bray s and Kurtz method; Determination of available potassium; Determination of avialable sulphur; Monocalcium phosphate extractables (Ensminger, 1954), Turbidimetric method (Massoumi and Cornfield, 1963), Ammonium acetate-acetic acid extractable S, Colorimetric method for determination of available sulphur using Barium Chromate (Palaskar et al., 1981), Determination of exchangeable calcium and magnesium, Determination of exchangeable sodium, Determination of Available Iron, Manganese, Copper, Zinc (DTPA extractable) by Atomic Absorption Spectrophotometer, Derermination of available zinc, Ammonium acetate dithizone extraction method, Determination of available manganese, Determination of available copper, Determination of available iron, Colorimetric extraction method, Determination of available molybdenum, Determination of available born 75, Curcumin method; Chapter 3: Testing for Edaphic Chemical Properties; Soil texture; Determination of texture, Hydrometer meter, International pipette method; Determination of bulk density of soil; Core sampler technique, Sand pouring technique, Paraffin cold technique, Paraffin cold technique; Determination of Soil Reaction (pH); Colorimetric method, Potentiometric method, Determination of electrical conductivity, Determination of cation exchange capacity, Determination of calcium carbonate; Rapid titration method; Dtermination of lime requirement of soil; Shoemaker et al method, Determination of gypsum requirement of Soil; Chapter 4: Plant Analysis; Analysis of plant tissue, Nitrogen, Dry ashing, Wet ashing, Determination of phosphorus; Vanadomolybdate method, Determination of potassium, Determination of micronutrient cations (Zn, Mn, Cu and Fe), Determination of boron, Determination of molybdenum, Interpretation of plant analysis of data; Chapter 5: Advance Methods of Soil and Plant Analysis; Plasma atomic emission spectrophotometer, Nitrogen analyzer as a tool for nitrogen estimation (ICAP-AES); Chapter 6: Analysis of Irrigation Water; Analysis of Irrigation Water; Collection of water samples; Sampling of water; Analysis of waters; pH, Total soluble solids; Gravimetric method, Electrical conductivity, Carbonates and bicarbonates, Chloride, Sulphate, Boron, Nitrate-nitrogen; Calcium and magnesium; Calcium, Magnesium; Sodium and potassium; Potassium; Residual sodium carbonate (RSC); Biochemical oxygen demand (BOD); Chemical oxygen demand (COD); Chapter 7: Laboratory Facilities; Laboratory equipments, Glassware and plasticware, Chemical and solutions
