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.作者: 場(chǎng)所 時(shí)間: 2025-3-22 15:38
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,作者: 場(chǎng)所 時(shí)間: 2025-3-22 19:19

Biological denitrification,echanism of N loss from soil. Since denitrification occurs only in the absence of oxygen, or at particularly low oxygen concentrations, it has been widely accepted as the cause of the poor efficiency of N use in flooded soils, where a well-developed anoxic layer is a characteristic feature (De Datta作者: 彎腰 時(shí)間: 2025-3-25 21:00
