Abstract
The dynamics of Cu fractions in the soils of Saurashtra region of Gujarat, India, was studied by collecting 169 surface soil samples (0-15 cm) from tagged cultivated farmers' field during the year 1990 and 2000. The results showed that overall there was a decline in EF, AF, total, residual, percent available and available total forms of Cu from 0.182, 1.232, 28.217, 26.558, 7.554 and 1.6565 ppm to 0.127, 0.834, 25.771, 24.509, 6.166 and 1.2676 ppm, while WS and RF of Cu increased from 0.0725 and 0.17 to 0.1206 and 0.186 ppm, respectively, over a period of 10 years in different soil groups of Saurashtra region of Gujarat. The status of DTPA available Cu was quite above the critical level.
