Popis:	An Investigation of the possible reduction of nitrate to ammonia during Kjeldahl digestion of soil drainage water samples by the perchlorate (+ V2O5 + Kl) method is reported. Non‐quantitative conversion was observed with samples containing 100 ppm or more of sucrose, an easily acid‐decomposible organic compound, and with 1000 ppm propanol, a less readily decomposible compound. No conversion was observed with samples containing either 10 ppm of sucrose or 1000 ppm of phenol.
