Creating Accurate Management Zones for Reliable Variable Seeding Results

To maximize the pay back from variable rate seeding, creation of accurate management zones are critical. Combining multiple layers of temporally stable data that accurately model in-field variability is an important first step. Combining these layers into one common productivity layer based on the soils overall ability to produce is a great way to accurately adjust populations. It is important to understand there is no clear linear relationship between population and yield. Local environmental conditions greatly impact what actually is the correct population. Populations set too high increase seed costs and also increase the risk of lodging and hence tremendous yield loss. Conversely, lower seeding rates will reduce costs, but may significantly cap yields in ideal growing conditions. The goal of variable rate seeding is to maximize yield on each productivity zone while reducing risk and expense of over seeding on lower producing soils. To truly fine tune seeding rates, it's important to implement flat rate in-field strip trials to compare the hybrid/population interaction. These strip plots should be scattered across several fields to model multiple environments. Precision ag technologies have significantly improved our ability to collect and analyze large amounts of data to make better decisions. Properly using these tools and technologies can greatly improve the likelihood of success.

Biography:
Scheiderer graduated from Ohio State University (ATI) with an associates degree in agronomy in 1980 and went to work in the retail crop protection and nutrient supply business for nine years working as an agronomist and/or a branch manager. In 1990 Dave and his wife, Zita, established their own business, Integrated Ag Services Ltd. (IAS). Dave went back to school and in 2004 completed his bachelors of science degree in agronomy from Ohio State University. Zita and Dave have 3 daughters, two married and the youngest is in college. He enjoys golf, most of the time, and spending time with his family all the time. The IAS business has grown and changed over the years; now has a staff of nine providing agronomic consulting services on over 200,000 acres in the west central Ohio area and beyond. Their focus is to still provide quality agronomic advice, but they now focus on the value of precision agriculture to return value back to the farmer.
