In the American West, wildfires are essential for keeping forests healthy. But the same fires that help release nutrients and promote new plant...
Speed Science - Cover Crops Fall SeedingLast Updated on 2014-03-01 17:48:56Published on Sep 13, 2013
Snapshot of the benefits of cover crops and when and how to plant them in the Midwest. Filmed at a cover crop field day, at Mark Jacobs' Farm in Hedrick, Iowa, September 11, 2013.
The video was developed in cooperation with Practical Farmers of Iowa, Iowa Learning Farms, and this project--the Cropping Systems Coordinated Agricultural Project, a regional collaboration supported by USDA-NIFA Award No. 2011-68002-30190. Filming and editing by Jamie Benning, a co-PI of this project's Extension Team.
Speed Science - Plot Design Options for On-Farm Cover Crop Trials - Mark Licht, Iowa State UniversityLast Updated on 2014-02-28 18:48:12Published on Feb 17, 2014
Mark Licht, extension field agronomist for Iowa State University, discusses strategies for planning, implementing, and testing cover crops. This lecture was part of the "Implementing Cover Crops to Improve Cropping System Resilience" workshop in Story County, Iowa, at the Field Extension Education Laboratory on April 2, 2013.
Two handouts referred to in this video are available at the Sustainable Corn Website at http://www.sustainablecorn.org/In_Fie....
The workshop was developed in partnership with the USDA-NIFA Sustainable Corn project. For more information about this project, see www.sustainablecorn.org. Other partners included Iowa State University Extension and Outreach, Practical Farmers of Iowa, Iowa Learning Farms, the Agricultural Research Service and North Central Sustainable Agriculture Research & Education.

Speed Science: Pitfall Tutorial - Mike Dunbar, Iowa State UniversityLast Updated on 2014-02-28 18:43:05Published on Feb 20, 2014
Mike Dunbar, PhD graduate student at Iowa State University, demonstrates how to prepare a pitfall for collection and study of insects/pests in corn fields. 2013.
This is one of a series of videos, with related, printable fact sheets, produced by scientists and farmers working together to create a suite of practices for corn-based systems that:
are resilient in times of drought
reduce soil and nutrient losses under saturated soil conditions
reduce farm field nitrogen losses
retain carbon in the soil
ensure crop and soil productivity
Speed Science - Nitrogen Canopy Sensors - Peter Scharf, PhD, University of MissouriLast Updated on 2014-02-28 18:41:07Published on Dec 11, 2013
Dr. Peter Scharf, Professor, University of Missouri, discusses the use of nitrogen sensing equipment to maximize efficiency and minimize loss of nitrogen fertilizer, and nitrogen management's potential to decrease production costs, increase crop yield and reduce greenhouse gas emissions in corn-based cropping systems.
This is an abridged version of his presentation made at the 2012 Annual Meeting of the Climate and Corn-based Cropping Systems Coordinated Agricultural Project - CSCAP [Sustainable Corn].
