| Abstract: | Both pot and plot tests were carried out to study the effects of nickel on wheat and rice grown on calcareous soil with nickel containing sludge applied. It appeared that wheat was more sensitive than rice and a 10% reduction in yield was caused when the soil content of nickel reached 130 ppm. It was concluded that the critical value of nickel content in calcareous soil is 155 ppm and 330 ppm should be the maximum permissible nickel contents in sludge for application. |
