AGQ Labs offers analytical services for Cadmium screening in agronomic soils, Cadmium analysis is important to control its degree of toxicity
AGQ Labs USA is a technological center with many years of analytical experience worldwide that offers various specialized services adapted to the needs of our clients.
Cadmium analysis is important because it is a toxic element, also referred to as a heavy metal, that is present in nature and its degree of toxicity will depend on the concentrations in which it can be found. It may be endogenous in certain soils, but when we focus on agriculture, the main sources of pollution are from phosphate fertilizers.
Cadmium (Cd) is an element that is rapidly absorbed by “leafy green” crops. For that reason AGQ Labs USA has been screening for Cadmium in soils at our headquarters in California. For the past several years we have found interesting outcomes when reviewing our results database of Cadmium concentration in soil. In 2016 the highest concentration detected was 4.61 ppm, the minimum value below the detection limit is <1.00 ppm and the average value was 1.85 ppm.
Cadmium analysis requires a correct sampling procedure. For a suitable composite sample, we recommend sampling the soil nearest to the root zone and about 1 foot deep. Sampling should be done every 5 acres, although the number of samples per acre will also depend on the type of crop.
There are some studies that confirm the effectiveness of foliar applications of zinc sulfate to decrease Cadmium concentration. For any questions or technical support about Cadmium analysis do not hesitate to contact our specialists.
