Abstract
Abstract Nitrapyrin, etridiazol, fenaminosulf, sodium azide, and a formulated product of aromatic substances and alkenes were evaluated as nitrification inhibitors under greenhouse conditions for radish ( Raphanus sativus L. ‘Cherry Belle’) fertilized with sewage sludge. Nitrapyrin and etridiazol inhibited nitrification, but their use restricted plant growth and lowered the Ca and Mg concentrations of the plants. Nitrification was inhibited slightly by fenaminosulf, which had little effect on plant growth and composition. Sodium azide and the formulated product were not effective as nitrification inhibitors. The azide was phytotoxic, but the formulated product had no toxic effects on growth. The toxic effects of chemicals with efficacy as nitrification inhibitors were due largely to the accumulation of NH 4 -N in the medium. Chemical names used: 2-chloro-6-(trichloromethyI)pyridine (nitrapyrin); 5-ethoxy-3-trichloromethyl-1,2,4-thiadiazole (etridiazol); and sodium p-(dimethylamino)benzenediazosulfonate (fenaminosulf).
