Course Description:
This course is a follow up to Principles of Crop Production and focuses on the in-depth production and management of corn, soybeans and some forages in the Midwest. Some of the topics include tillage methods, planting procedures, weed, insect and disease identification, precision farming, nutrient requirements, and harvesting and storage. The basic understanding of management practices is vital for students in implementing critical thinking skills involved in the decision-making process. The is necessary for those students working in the area of Agronomy.

Student Learning Outcomes and Objectives:
Student Learning Outcomes
1. Describe the growth and development of corn, soybean, small grains, and forages and recognize how stage of growth influences management decisions.
2. Create crop management strategies to real-world production situations and the impact management decisions have on growth, and yield, of a crop.
3. Develop strategies that optimize inputs and conserve the natural resources needed to produce quality, high-yielding crops.
