  • The February orchid (Orychophragmus violaceus)-spring maize rotation system is established to resolve the problems caused by the expansion of fallow fields in North China. Based on a site-specific experiment, temporal and spatial variations of soil NO(3-)-N were investigated during the period from February orchid incorporation to maize harvest. The results showed that the nitrate content in soil profiles not only showed a temporal characteristic, i. e., increasing at the beginning of the maize… CONTINUE READING
