To elucidate the influence of H2S on nutrient absorption and metabolism of nitrogen and carbohydrate, a solution culture experiment was carried out. Just after the addition of H2S to the solution, absorption of K2O and SiO2 was inhibited at first accompanied with such disturbances in carbohydrate metabolism as an increase in reducing and non-reducing sugar contents, and a decrease in starch content. But afterward when the inhibition of nutrients absorption and carbohydrate metabolism became extreme, nitrogen metabolism was also disturbed, resulting in the increase in soluble-N content and decrease in protein-N content.
