Denitrification losses in flooded rice fields, and ecological significance of these processes in the gain or loss of N from a flooded soil and sediment system has been studied by several researchers. The objective of this paper is to review recent research findings on the significance of nitrification-denitrification in flooded rice soils.作者: 冷淡一切 時(shí)間: 2025-3-22 11:24 作者: Maximize 時(shí)間: 2025-3-22 15:36
New developments in nitrogen fertilizers for rice, in a variety of settings from the laboratory to the farmer’s field. Novel N fertilizers currently at various stages of testing include urea supergranules for deep placement, urea coated with various materials to control the N release rate, mixtures of a urease inhibitor with urea to reduce losses, and organic N sources other than urea.作者: 做作 時(shí)間: 2025-3-22 19:49
