Technology to determine the nitrogen fertilization needs of corn by analyzing leaves and stems
Abstract
Nitrogen (N) fertilization is a common practice in corn planting in Venezuela, and the determination of doses and methods of application is based on studies of the response to the application of this chemical element. However, a mechanism is needed to supplement corn fertilization with N during its development.
