Long-term Optimum Nitrogen Rate for Corn Yield and Soil Organic Matter

This project began with a uniformity trial conducted in 2008 at Elora, Ontario. Long-term and short-term N rate treatments commence in 2009.

Objectives

1. Assess short-term and long-term effects of N in maize production on productivity, environmental impact, profitability, and cropping system sustainability.
2. Support the validation of crop models, such as Hybrid Maize, for simulating yield potential, seasonal growth and yield, and fertilizer N management requirements.
