Abstract
RUI, Yu-kui; ZHANG, Fu-suo and SHEN, Jian-bo. Effects of nitrogen fertilization on heavy metal content of corn grains. Phyton (B. Aires) [online]. 2009, vol.78, n.2, pp.101-104. ISSN 1851-5657.
Nitrogen fertilization has played a significant role in increasing crop yield, and solving problems of hunger and malnutrition worldwide. However, excessive nitrogen inputs do not significantly increase crop yields but may lead to many serious environmental problems. The effects of nitrogen fertilization rate were studied on heavy metal content of corn grains. Our results show that nitrogen fertilization management is beneficial for reducing production costs, protecting the environment, and improving the quality of farm products.
