Abstract
We compared the effects of adding different forms of nitrogenous ferti lizers on the production of CH4 in soil and on CH4 emission from rice plants, Urea and diammonium phosphate gave the highest rates of CH4 pr oduction from the soil and emission through rice plants, followed by ( NH4)(2)SO4. NaNO3 was the least effective. The effects of micronutrien ts like Mo, Ni, or B were more prominent than those of Fe, Mn, Zn, V, or Co, It is concluded that CH4 emission from rice paddies is influenc ed by both macro- and micronutrients, through effects on both microbia l methanogenesis in soil and elimination through rice plants as a cons equence of the effects on plant growth.
