Understanding Alternative Nutrient Amendments – Virtual Series

June 25, 2024 6:30 pm to July 30, 2024 7:30 pm
June 25, 2024


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.

June 25 to August 6 2024

Session Description

You’re invited to a summer webinar series with local and passionate professionals discussing the world of nutrient amendments that can be used to help producers in transitioning from synthetic nitrogen fertilizer, assist in utilizing resources, and adding nutrient and microbial diversity in agricultural systems through the use of composts, manure, by-products, and more. We are allocating 40 minutes for presentations with 20 minutes for discussion with each webinar. We hope for lots of discussion and questions!

Please Note: Due to technical difficulties, some webinar dates and topics have shifted. Check out the updated schedule and register for the new dates!

Event Details

Webinar 1: June 25, 6:30 PM – 7:30 PM

Introduction to Nutrient Amendments
Guest Speaker: Gordon Price, PhD

Gordon is passionate about utilizing wastes and resources as valuable products within agricultural systems. He is a professor at Dalhousie’s Faculty of Agriculture, specializing in waste management, composting systems, soil science, and environmental management. His research interests’ range with a focus on sustainable agriculture and ecosystems, interactions between urban and peri-urban systems, and enhancing opportunities to utilize organic by-products (wastes). He also works with the Innovative Waste Management Analytical Lab, which was designed to meet emerging research demands for soil, organic wastes, and environmental analysis and the Integrated Vertical Farm- Cabon Recovery from Composting System in collaboration with Divert NS and Hatch Inc.

The first webinar will explain and differentiate different types of nutrient amendments, including their characteristics, uses, and compositions such as manures, compost, and other widely used amendments. We will also discuss management considerations, restrictions, and the economics of different nutrient amendments that are available in Eastern Canada.

Webinar 2: July 9, 6:30 PM – 7:30 PM

Management Considerations for use of Soil Amendments
Guest Speaker: Gordon Price, PhD

The second webinar will dive into compost specific management practices and considerations such as nitrogen management, sampling, equipment, incorporation methods, sourcing and transportation, timing and pre-harvest intervals, as well as regulations.

Webinar 3: July 16, 6:30 PM – 7:30 PM

Converting Organic Matter Into Plant Nutrients: The Role of Soil Biology
Guest Speaker: David Burton, PhD FCSSS

Dr. David Burton, is a Soil Scientist and Director of Dalhousie’s Centre for Sustainable Soil Management. His research focuses on the soil nitrogen cycle in the context of soil fertility and environmental impact. His current research examines the production and consumption of greenhouse gases in natural and agricultural landscapes, the development of tools for the measurement of soil nitrogen supply to plants, the influence of climate on soil biological processes, and the assessment of soil health. It is the aim of this work to better understand the factors that control soil microbial processes and to use this information to develop sustainable land management systems in a changing climate.

The third webinar is all about how different nutrient amendments interact with soil microbes and soil ecology. We will discuss the biochemical reactions and how different organic nutrient amendments impact nitrogen mineralization and immobilization depending on composition and management practices.

Webinar 4: July 23, 6:30 PM – 7:30 PM

Biostimulants in our Systems
Guest Speaker: Av Singh, PhD

Av Singh is one of the leading proponents of regenerative organic agriculture, being engaged in projects across six continents. Dr. Singh has authored over 250 peer-reviewed papers, chapters, and extension articles and has been an invited speaker to over 600 workshops, conferences, symposia as well as guest-lecturing at over 30 universities in Canada, the US, the UK, and India. Av has had the privilege of visiting over 2500 farms across five continents which has shaped his extension of holistic, system-based design solutions. Emphasizing a union of traditional knowledge with science, Av works with growers to cultivate an appreciation of plant: soil interrelationships.

The fourth webinar will discuss the ins and outs of biostimulants and how they interact with soil microbial populations, how this impacts nitrogen availability, and impacts on plant health. We will discuss the details of common products, new ones, and favourites that are on the market. We will touch on humics, extracts, and microbial inoculants, as well as how to make your own.

Webinar 5: July 30, 6:30 PM – 7:30 PM

Conversion Approaches for Raw Materials to Soil Amendments
Guest Speaker: Gordon Price, PhD

The fifth webinar will dive into the types of biomass and resources, and processes available to convert organic inputs into nutrient amendments. Here we will touch on local products and the production of those products including high nitrogen products such as dehydrated poultry manure, blood meal, feather meal, and more.

Webinar 6: August 6, 6:30 PM – 7:30 PM

Let’s Discuss Biosolids
Guest Speaker: Gordon Price, PhD

In our sixth webinar we will learn about biosolids and their current place in agricultural systems as a nutrient amendment. We will discuss their value as a nitrogen source, opportunities, rules and regulations, microplastics, and management considerations.
