Plant assimilation and nitrogen cycling,the N-source. There is little information on long-term effects of crop N-nutrition on acidity, and acidity is a critical factor that affects agricultural productivity in many tropical soils. Thus, plant control of pH and the acid/base balance in the soil as a consequence of nitrogen uptake and assimilation are important areas of future research.作者: 間諜活動(dòng) 時(shí)間: 2025-3-29 04:47 作者: 專(zhuān)心 時(shí)間: 2025-3-29 09:41
