Figure 4: Comparison of metal and nutrient status of amended and
routinely made Jaivik Poshak
It was seen that the metal
concentration was within limits for all metals except for Cadmium in the
product made from in-house compost. The Cadmium concentration was
approximately 10 times lower in the modified product and hence can be
stated to be safe for agricultural application. In terms of nutrient
status, the modified Jaivik Poshak was lower in Boron, Sodium and Cobalt
content only with respect to the product prepared normally with in-house
compost. The concentration for nine other nutrients was higher in the
modified product. The percentage increase in the nutrient concentration
was seen to range from a minimum of 6.5% for copper to up to 863% for
Phosphorous as can be visualized from Figure 4.
The comparison of results for Jaivik Khad is shown in Figure 5 below.
