Interested in $10 corn and $30 soybeans for certified organic, but not sure how to transition?

Biwek Gairhe¹, Sarah Hirsh², and Ray Weil¹
¹Department of Environmental Science and Technology, University of Maryland College Park
²University of Maryland Extension, Somerset County

Organic grain production is promoted for greater potential profits with premium grain prices, improved soil health with organic inputs and fewer environmental hazards in the absence of synthetic chemical use. However, the three-year period required for organic certification is a challenging phase when transitioning farmers are learning to do without synthetic chemical manage soil fertility, weeds, diseases and pests, while not...Read more

Pesticide Recertification Workbook

A team of Extension agents from University of Maryland, University of Delaware, and Penn State have produced a workbook for applicators that do not have access to our virtual training materials. This workbook is intended to give Maryland Private Pesticide Applicators the recertification training (4 credits) needed to renew the applicator’s license. Topics covered in this workbook are MDA-approved and are equivalent to two hours of in-person training needed every three years to renew your private applicator’s license. This workbook is also approved for three (3) Delaware credits and two (2) core Pennsylvania credits. 

In order to receive credit you must complete the entire workbook. At the end of the workbook you will answer a 30-question quiz and return it to the Baltimore County Extension

To order your free workbook, please call the Harford County Extension office at (410) 638-3255.
