The 0.02 pounds of cadmium applied per ton results in 0.06 pounds applied to the soil, which is far less than that detected in the fodder as shown in Table 1. One ten-millionth of that in the soil found its way to a goat s liver. This proves to be a reasonable risk, even for those who eat more liver than the average consumer. Reactions in the soil Reactions in the soil explain what happens to the elements listed in Table 2 when biosolids are applied to the land. However, a few reactions will explain what happens to most.
Soil organisms attack the dead microbial bodies through decomposition.
These can be taken up by plants and reused. The cation exchange capacity measures the soil s ability to hold cations. All will be held by cation exchange and tend not to leach. Anion exchange and retention. They may be sorbed on the surface of the soil by several different mechanisms, making these anions quite immobile.
