Rufus Chaney

Consultant in Environmental Agronomy. Conduct evaluation of potential risks from heavy metals and micronutrients on plants and the food-chain including phytoavailability and bioavailability.

Short bio

During 47 years working with the US Dept. Agric, Agric. Res. Serv., I conducted research on Fe uptake, chlorosis of soybean, beneficial use of biosolids and composts on land, risks from metals in urban gardens, and crop uptake of Cd and crop Cd bioavailability to animals. Also invented phytoextraction to remove metals from contaminated soils or phytomining using hypernickelophore plants. Led team which characterized Cd accumulation by confectionery sunflower kernels in relation to soil properties and genetics. Identified high chloride played a significant role in Cd accumulation among farms. Evaluated sunflower genotypes for Cd accumulation and bred low Cd inbreds to make low Cd hybrids. Did feeding studies to assess the inhibition of Cd absorption from diets with varied Fe, Zn and Ca and showed the bioavailability could vary substantially. One should not study Cd alone because Cd and Zn compete for sorption in soils and for uptake by roots.
