“…Water adsorption isotherms of North Dakota lignite (PSOC-246) and some of its chars were obtained gravimetrically, using a vacuum desicator technique similar to Puri's 70 in his studies of hygroscopic moisture from some Indian soils. Puri's data 70 giving the relation ·-5'6 -between sulfuric acid normality and relative humidity of H2SO~-H20 mixtures ( Figure 21) were used to select the relative humidities of the solutions at which water adsorption was determined.…”

“…The soil pH was measured from the soil saturation extract as per the procedure given by Richards (1968) on pH meter. The calcium carbonate in soil samples was determined by the method of Puri (1949) and expressed as percent. Organic carbon was determined by the method of Walkley and Black as reported by Jackson (1973) and expressed in percent.…”

Abstract'Kinnow' decline was studied in relation to soil plant nutritional status under semi arid condition of Hisar (India). There were no differences between the soil pH, electrical conductivity and calcium carbonate of healthy and declining trees. The soil under the healthy trees had significantly higher organic carbon (0.46%) than that under declining trees (0.35%). The nutrients viz., N, P, Zn, Cu, Mn and Fe in the soil under healthy and declining trees did not differ significantly except K. Leaf N, Zn, Cu, Mn and Fe were significantly more in the healthy trees. The deficiency of N, P, Zn and Mn in the leaves of both categories of trees could be attributed to low contents of these nutrients in the soil under healthy and declining trees. Growth, yield and fruit quality were better in healthy trees as compared to declining trees. The yield on kg per tree basis in declining trees reduced (8.43 kg/tree) as compared to that in healthy trees (20.74 kg/tree). Low organic carbon, soil N, Zn and Mn content could be associated with the declining problem of 'Kinnow' .

The present hydrogeochemical study was confined to the Thoothukudi District in Tamilnadu, India. A total of 100 representative water samples were collected during pre-monsoon and post-monsoon and analyzed for the major cations (sodium, calcium, magnesium and potassium) and anions (chloride, sulfate, bicarbonate, fluoride and nitrate) along with various physical and chemical parameters (pH, total dissolved salts and electrical conductivity). Water quality index rating was calculated to quantify the overall water quality for human consumption. The PRM samples exhibit poor quality in greater percentage when compared with POM due to dilution of ions and agricultural impact. The overlay of WQI with chloride and EC corresponds to the same locations indicating the poor quality of groundwater in the study area. Sodium (Na %), sodium absorption ratio (SAR), residual sodium carbonate (RSC), residual sodium bicarbonate, permeability index (PI), magnesium hazards (MH), Kelly's ratio (KR), potential salinity (PS) and Puri's salt index (PSI) and domestic quality parameters such as total hardness (TH), temporary, permanent hardness and corrosivity ratio (CR) were calculated. The majority of the samples were not suitable for drinking, irrigation and domestic purposes in the study area. In this study, the analysis of salinization/ freshening processes was carried out through binary diagrams such as of mole ratios of SO 2À 4 /Cl -and Cl -/EC that clearly classify the sources of seawater intrusion and saltpan contamination. Spatial diagram BEX was used to find whether the aquifer was in the salinization region or in the freshening encroachment region.
