The volatile substance(s) from 100m molal of urea-amended natural soilcaused complete loss of sclerotial viability. No inhibition was observed in sterilized soil with the same treatment unless 0.1% of urease were subsquently added. Gaseous ammonia was apparently one of the volatile substances involved in the toxic effect. The production of ammonia was detected one day after urea amendment. Which then reached its maximum production five days later. The sclerotial germination but not survival was inhibited only slightly when sclerotia were exposed to the atmosphere of urea-amended natural soil from which the ammonia producedwas removed by sulfuric acid. Though urea itself or the volatile substance(s) thus produced increased the soil pH after urea amendment, theincreasing rate was not proportional to the amount of urea added. SoilpH was 7.1 when urea content was 0.1% pH 8.8 when urea was 0.3 or 0.4%. The volatile substance(s) produced from nitrogenous compounds in soil a pH 6.4 were much less inhibitory to the germination of sclerotia compared to that produced from soil at pH 7.8. Except for ammonium chloride treatment in which sclerotia showed scanty germination, sclerotiain both ammonium sulfate and ammonium nitrate treatments at pH 7.8 failed to germinate completely. Survival of sclerotia was not affected in these nitrogenous compounds amended acidic soil for 7 days. In alkaline soil, however, sclerotia from ammonium nitrate and ammonium chloride treatments retained only 80% viability. whereas in ammonium...
