Nitrogen dynamics in soil
Webb摘要： A field experiment was carried out to study the effect of nitrogen (N) fertilizer rate (0, 120 kg N hm -2 , and 240 kg N hm -2 ) on summer maize (Zea mays L. var. Shaandan 911) and soil water-nitrogen dynamics. WebbNitrogen is a macronutrient that is often limiting to plant growth in temperate ecosystems, although it may be a pollutant in aquatic ecosystems and drinking water. It is rapidly …

WebbVarious environmental factors and anthropogenic practices can affect the Fe biogeochemical cycles in soils. Nitrogen and carbon states are closely associated with Fe dynamics. However, we still have a limited understanding of the complex response of Fe biogeochemical processes to long–term nitrogen– and organic–fertilization regimes. WebbHere we present an overview of the standardized datasets, including hydrographic profiles, remote sensing reflectance, temperature and salinity, particle absorption, nutrients, dissolved organic carbon, particulate organic carbon, particulate organic nitrogen, CDOM absorption, fluorescent dissolved organic matter intensity, suspended particulate …
