Agricultural systems are nitrogen (N) deficient throughout the world and N is the most
important nutrient in realizing the maximum potential of the crop and sustainability of the …

Improvements of nitrogen use efficiency (NUE) may be achieved through the use of sensing
tools for N status determination. Leaf and canopy chlorophyll, as well as leaf polyphenolics …

针对当前我国农业生产面临增肥不增产, 土壤养分过量累积, 化肥施用过量和养分利用效率下降
等重大问题, 本文综述了中国土壤养分与植物营养状况的历史演变和研究进展 …

The relationship between nitrous oxide (N2O) flux and N availability in agricultural
ecosystems is usually assumed to be linear, with the same proportion of nitrogen lost as …

Over N fertilization is a common problem for the winter wheat (Triticum aestivum L.)–summer
maize (Zea mays L.) rotation system in the North China Plain. A field experiment which …

Improved prediction of optimal N fertilizer rates for corn (Zea mays L.) can reduce N losses
and increase profits. We tested the ability of the Agricultural Production Systems sIMulator …

Nitrogen fertilizer is typically applied to corn (Zea mays L.) shortly before planting, but there
are several reasons why later N applications may be of interest: to spread work away from …

An accurate estimate of nitrate (NO3N) leaching from agricultural land is critical to
environment impact studies. Although NO3N are almost always present in groundwater …

The DAYCENT ecosystem model (a daily version of CENTURY) and an emission factor (EF)
methodology used by the Intergovernmental Panel on Climate Change were used to …

Corn (Zea mays L.) grain is a major commodity crop in Illinois and its production largely
relies on timely application of nitrogen (N) fertilizers. Currently, growers in Illinois and other …
