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.
