Agricultural activities that directly increase `N_2O` emissions are fertilization, application of manure or oth er organic materials, retention of crop residues, production of nitrogen-fixing crops and for ages, and cultivation of soils with high organic matter con tent. Irrigation, drainage, tillage practices and fallowing of land also increase `N_2O` emission.
