Influence of sea salts on the soil metabolism

Abstract

Abstract Gaseous metabolism in soils has been studied by many researchers. DE and Digar (1, 2) demonstrated that denitrification takes place in the paddy soils in India. BREMNER and SHAW (3) found that denitrification is accelerated in soils when glucose and nitrate are added. ALLISON and DOETSCH (4) and ALLISON et al. (5) proved that nitrogen is formed by the interaction of nitrite and amino acids. HAUCH and WELSTED (6) studied the denitrification in soils using 15NO3−. They found out by means of mass spectrometer and infrared spectrometer that 60 % of NO3− is reduced to N2O and N2 in soils. Yamane (7) reported that NO3− is quantitatively reduced to N2 in waterlogged paddy soils. Shioiri and Tanada(8) made a detailed study on the metabolism of nitrogen in paddy soils. Koyama(9) indicated that a large amount of nitrogenous nutrients is escaped into the atmosphere as N2, on the basis of Ar/N2, ratio in the waterlogged paddy soils.
