Abstract

A field experiment was conducted to study the effects of selenium mixed with.Cobalt on soil fertility of alfalfa(Medicago sativa L.)grassland by leaf-spraying of Selenium and Cobalt fertilizers in different growth duration of alfalfa based on soil and climate conditions of Yellow river beach in Henan province.The results showed that Selenium fertilizer can promote growth of root nodule of alfalfa in a depth of 0~20cm soil,improve top soil structure and enhance the contents of organic matter and quick-acting N significantly.Effective combination of Selenium and Cobalt fertilizers can not only enforce the performance of Selenium,but also promote the content of Quick-acting K in a depth of 0~20cm soil.
