Project Title:

The Effect of Soil Amendments on the Uptake of Cadmium by Rice.

Researcher:

Dr.Chitsanuphong Pratum

This study aims to determine the type of the effective soil amendments for cadmium absorption in the paddy soil. It also investigated the amount of cadmium accumulation in various parts of the rice plants. The research methodology was performed in Completely Randomized Design (CRD), which three replications. The Suphanburi 1 rice variety and 4% of soil amendments (pig manure, dairy cow manure, poultry manure – rice husk, organic compost, and vermicompost) were used for this study. The cadmium contents in each the paddy soil samples were 20, 40, and 60 mg/kg dry weight, respectively. The results found that the rice plants cannot grow wither and die on the 70th day of cultivation at 4% of dairy cow manure and pig manure. In addition, poultry manure – rice husk was highly effective for cadmium adsorption in the paddy soil. Whereas, organic compost can stimulate the roots of the rice plants to absorb cadmium in soil were more. This reduces the accumulation of cadmium in stems, leaves, and especially rice grain. In part of, the investigation of the amount of cadmium accumulation in various parts of the rice plants found that the cadmium accumulation in roots > stems > leaves > rice grain, respectively.
