Organic liquid amendments in the reduction of cadmium in soil, leaves and cocoa beans

The objective of the study was to evaluate effect application two organic amendments (biol and liquid carbon) on cadmium soil, leaves almonds cocoa crop, plantation CCN-51 (Theobroma cacaoL.), five years production, in province Huamalíes, Huánuco region, Peru. research used a completely randomized block design (RCDB) with factorial arrangement 3 x + 1 additional control. Total leavesand beans evaluated. lowest content total soil determined when applying 50 L/ha biol (0.13 ppm cadmium) 4 carbon (0.12 cadmium); while, without amendments, average value 0.36 cadmium. Likewise, T5 (80 4L/ha reduces available by 73.58%; while T4 decreases 43.83% 62.96%, respectively.
