Figure 5: Comparison of metal and nutrient status of amended and
routinely made Jaivik Khad
From the analyses we found the mercury concentration to be marginally
higher in the amended product with respect to the permissible limit. For
Cadmium too, the measured concentration is higher than the limit
although for the amended product it is marginally higher or almost at
par with the recommendation. From the viewpoint of Cadmium, the amemded
product is safer than the routinely made Jaivik Khad. With respect to
the nutrient concentrations, Nickel and Copper are higher in the amended
product as compared to the routine product although the concentrations
present are good for plant growth.
Figure 6 below shows the comparative analyses for Jaivik Prom.
