304 ANAIS DA TERCEIRA REtTNIÂO BRASILEIRA DE CIÊNCIA DO SOLO crescimento do fungo quando o S é fornecido apenas pela réserva do solo posto no meio nutritive Assim, hä a possibilidade de se determinar por interpolaçâo — como é feito no método da plaça de Cunninghamella de Mehlich para fósforo — a quantidade de S assimilâvel que o solo possui. SUMMARY Aspergillus niger growth — as measured by the dry weight of mycelium pads — in MULDER,S medium with increasing amounts of S follows MITSCHERLICH',s equation. On the other hand there is great difference in the growth of the fungus when sulfur is supplied only by the soil placed in the nutritive medium. Hence, there is the possibility of determining by interpolation — as in MEHLICH'S Cunninghamella plaque method for phosphorus — the supply of available sulfur in soils.
