Manure Management to Improve Nitrogen Efficiency, Soil Health and Reduce Greenhouse Gases

Tuesday, 12:00 pm to 1:30 pm
January 31, 2023


This event is being held as part of the On-Farm Climate Action Fund (OFCAF) program. The goals of the program are to encourage on-farm sequestration of carbon and reduction in greenhouse gases through the implementation of improved nitrogen management, enhanced cover crop adoption, and the normalization of rotational grazing.

Session Description

In this session, OMAFRA’s Sustainability Specialist Christine Brown will discuss manure application rates/technology using 4R principles, cropping systems, manure usage on forage and some of the benefits of manure in improving soil health. Stick around afterward for Perennia’s Agricultural Environmental Specialist Mackenzie Rathgeber to go through some manure calculations! 

Guest Speaker

Mackenzie Rathgeber, Agricultural Environmental Specialist  

Mackenzie’s role at Perennia Food and Agriculture Corporation is to support and promote best management practices and guidelines related to climate change, biodiversity and environmental health in agriculture. 

Mackenzie has a Bachelor of Science in Agriculture from Dalhousie’s Faculty of Agriculture, with a major in Environmental Science. After graduating with her Bachelor of Science, Mackenzie worked for the Canadian Forage and Grassland Association and wrote a Forage Best Management Practices Manual with a focus on best management practices which could help reduce or offset greenhouse gas emissions, with a focus on enhancing carbon sequestration. Mackenzie is completing a Master of Science in Animal Science from Dalhousie’s Faculty of Agriculture. Mackenzie’s research focuses on rotational grazing intensity of beef cattle and how it may improve animal performance and enhance carbon sequestration to help offset net greenhouse gas emissions from the beef life cycle. 

Led by Perennia Food and Agriculture in conjunction with New Brunswick Soil and Crop Improvement Association and the Prince Edward Island Federation of Agriculture.
