Synopsis

Synopsis

Time rates of change in corn yields under nitrogen fertilization in a long term experiment are estimated. The experiment includes four rotations, each containing two years of corn and from zero to three years of meadow. Three levels of nitrogen are applied to the corn in each rotation. A model is presented which is characterized by the measuring of time in terms of rotation cycles and by the assumption of an exponential approach to a limiting value.
