CLG 108
Redefining the Field Edge: Improving Farm Profitability with Strategically Placed Prairie
Many farms have marginal land currently in crop production that does not return a profit in most growing seasons—whether from frequent flooding, poor soil quality, excessive slope, or machinery access challenges. Redefining the field edge, by strategically converting unprofitable parts of the field to perennial vegetation, benefits both the landowner and the environment.

ArcGIS Pro Field Calculations: Area and Length
As a GIS student or professional, you may be asked to compute basic geometric calculations in ArcGIS Pro. This is fairly easy to accomplish, but requires understanding how Fields operate in ArcGIS Pro. In this tutorial, you will practice adding a field to an attribute table and learn how to calculate area and length for a given polygon or line feature. These measurements may be helpful in a variety of contexts: architectural, as in determining the footprint of a series of buildings; ecological, as in the distance salmon travel from a lake to the sea; or agricultural, as in determining potential yield from a crop of corn, among many others.

ID 433
Midwest Cover Crops Field Guide 3rd Edition
The updated and expanded edition of this popular, 162-page guide includes nearly 30 pages of new material, including cover crop suggestions for common rotations, up-and-coming cover crop species, effects on yields, climate considerations, and more.

Producers who want to prevent soil erosion, improve nutrient cycling, sustain their soils, and protect the environment have been returning to a very old practice: planting cover crops.

Although farmers have been using cover crops for centuries, today's producers are part of a generation that has little experience with them. As they rediscover the role that cover crops can play in sustainable farming systems, many growers find they lack the experience and information necessary to take advantage of all the potential benefits cover crops can offer. That inexperience can lead to costly mistakes.

This guide will help you effectively select, grow, and use cover crops in your farming systems. While this guide isn't the final word on cover crops, it is meant to be a useful reference.

Available for purchase through Purdue University.
