描述A growing interest has been shown recently in the dymanics of nitrogen in agricultural and natural ecosystems. This has been caused by increasing demands for food and fibre by a rapidly expanding world population, and by a growing concern that increased land clearing, cultivation and use of both fertilizer and biologically fixed nitrogen can have detrimental effects on the environment. These include effects on water quality, eutrophication of surface waters and changes in atmospheric composition all caused by increased cycling of nitrogenous compounds. The input and availability of nitrogen frequently affects the productivity of farming systems more than any other single management factor, but often the nitrogen is used inefficiently. Much of the fertilizer nitrogen applied to the soil is not utilised by the crop: it is lost either in solution form, by leaching of nitrate, or in gaseous forms as ammonia, nitrous oxide, nitric oxide or dinitrogen. The leached nitrate can contaminate rivers and ground waters, while the emitted ammonia can contaminate surface waters or combine with atmospheric sulfur dioxide to form aerosols which affect visibility, health and climate. There is also c

Gaseous nitrogen losses from plants,his physiological period proteins break down in senescing leaves, liberating NH. (Thimann 1980). Gaseous losses of NH. are therefore possible, and have indeed been found. Gaseous losses of other reduced forms and of oxidized forms have also been found. In addition, losses as N. have been postulated.

Agronomic and technological approaches to minimizing gaseous nitrogen losses from croplands,hemical properties of N fertilizers, and improved crop and soil management practices. Some of the methods directed toward reducing gaseous N loss from cultivated soils also may increase the efficiency of plant use of N by decreasing the movement of inorganic N in solution from the plant rhizosphere,

It is constantly being formed in soils at rates wh

It was generally assumed that the important pathways of loss were volatilization of NH., and reduction of nitrate to N.O and N. by soil microorganisms (biological denitrification). There was little direct evidence to support the assumption of significant losses via these pathways, despite
