No-till on the Plains is holding a Whirlwind Expo on July 14 at the Mindemann Farms near Apache, Okla. Speakers and presentations include:

• The Oklahoma NRCS staff will demonstrate the importance of residue cover for erosion prevention using a rainfall simulator. They will also show the importance of soil structure that can be restored and built using continuous no-till systems.
• Greg Scott, a soil scientist out of Tyron, Okla., will discuss soil quality, soil structure and the positive impacts of continuous no-till on soil health.
• Oklahoma State University machinery specialist Randy Taylor will share his reearch on no-till seeding systems, GPS accuracy, yield monitor data, using sensors in variable rate application of crop inputs and seeding equipment for no-till systems.
• Matt Alig, a no-tiller in Okarche, Okla., will talk about his unique no-till system. Alig has been no-tilling since 1997 and his operation consists of both cropland and grass. He prefers to graze crops rather than harvest grain given the extreme weather variability of freeze and hail risk, and is using several species for pasture and cover crops.
• Jimmy Emmons is a no-tiller in Leedey, Okla., who will share what he's learned from using no-till and cover crops. Emmons started using cover crops 3 years ago as a way to improve soil health and invested in soil moisture probes to assess how much water they were actually using.

Lunch will be served at the Caddo Kiowa Technology Center, located at 415 7th St. in Fort Cobb, OK 73038. Registration is $30 by July 10 and will increase to $50 on the day of.
