Effects of Some Environmental Factors on Release of Chloride to Overlying Water from Selective Fertilized Soil of Udaipur District, Rajasthan

The range of chloride in the experimental medium maintained at higher temperature of 32? C varied between 0.0 to 25.0 ppm in both black and red soils. In the red soil the average per hour release was 1.235 while in the black soil the same was 1.123 ppm. As regards the experiments as the lower temperature, the values are more than that of higher Temperature (0.0 to 60.0/40.0 ppm) in the case of red and black soils respectively. The per hour release in both the soils was however, higher (1.842 for red soil and 1.561 ppm in black) than in the experiments at elevated temperature of 32? C. The percentage drop was 15.26% in black soil in relation to red (Table 7.2, Fig 7.3 and 7.4). The per hour release being 1.460 in red while, 0.786 ppm in the black soil (Fig 7.5 and 7.6). In the alkaline pH the results were matching, the average per hour release being 0.449 for red and 0.561 ppm for black soil (Table 7.4, Fig 7.7 and 7.8). The per hour release in the lux values of 565 and 590 varied between 0.0 to 33.0 ppm in red soil and between 0.0 to 28.0 ppm in black soil. In the case of the lux value of 6000, the chloride release obtained was 0.0 to 30.0/25.0 ppm in the two soils. As regard the percentage drop in average per hour release was more in black soil with 15 and 60 watt bulbs (590 and 3900 lux), while the same was more in red soil being 15.96 with 6000 lux and only 0.32% in 6500 lux. The average per hour release of chloride in the case of black was 1.786 in relation to 1.741 ppm of red soil. The percentage drop in average per hour release of chloride was 9.07 in black soil in relation to red soil. The percentage drop in average per hour release of chloride was 15.26 in black soil in relation to red. The chlorides are the salts resulting from the combination of the chlorine with other metallic ions. But in the case of 6000 lux the chloride release was low and in the case of 3900 lux the chloride release was again high. In nature, the higher illumination would initiate higher photosynthetic release of oxygen, which may also be playing role in more chloride release.
