Guest bio

Ian and Jo-Anne Cushon, along with their son Liam, operate Moose Creek Organic Farm at Oxbow, Saskatchewan. The farm is in southeast Saskatchewan in the thin black soil zone. The primary crops grown are wheat, oats, flax, hemp, and alfalfa seed. Ian started farming in 1981 and began converting to organic farming in 1985. After 30 years of organic farming, protecting and improving the soil and managing fertility with crop rotations and off-farm inputs on 5000 acres, requires continued learning, experimentation and lots of patience.

Creating a nutrient budget will help you evaluate the effect of nutrient management on your fields’ sustainability and help you assess efficiency and improve resource allocation. The Nutrient Budgeting Web App was developed to help with multi-year nutrient management planning, especially for producers that rely on biological nitrogen fixation and/or occasional inputs of manure or other soil fertility amendments. This multi-year approach to nutrient management planning can help to optimize production while decreasing nutrient loss to the environment by doing a better job of matching soil nutrients to crop needs.

The Nutrient Budgeting App will help you calculate whether nutrients are accumulating or being depleted from your fields over time. It makes it easy for you to add up the nutrients you are bringing onto your fields (including through N fixation by legumes) and subtract the nutrients that leave your fields to help you plan your crop rotations and soil amendments. The NBA is meant to be used alongside other nutrient management tools, such as soil testing.

Whether you are an organic producer, transitioning to organic production or a conventional producer wanting to better understand how legumes in your rotation can help you reduce synthetic nitrogen use, the NAB will help you understand the efficiency and flow of nutrients in your fields.

Joanne Thiessen Martens

Dr. Joanne Thiessen Martens is Assistant Professor of Soil Chemistry and Fertility in the Department of Soil Science at the University of Manitoba. She teaches and conducts research on soil fertility and nutrient flows in agroecosystems, especially phosphorus dynamics and alternative crop production systems, including organic production. Her current research focuses on the interactions among soil, plants, and fertilizers, especially with recycled phosphorus inputs like struvite, as well as strategies to increase sustainability and resilience in prairie cropping systems. Joanne has worked with farmers, agronomists, extension personnel, and researchers across Manitoba and Canada, as well as internationally.

Canada Grazing Exchange

A free online platform connecting livestock owners with landowners across Canada who have available grazing land or cover crops. A great tool to help improve soil health and make the most of forage opportunities.

Gateway Research Organization (GRO)

Based in Westlock, Alberta, GRO is a local Applied Research Association offering practical, science-based information on topics like soil health, pasture management, and livestock. They host regular winter "CropTalk" sessions and pasture webinars—perfect to catch live or rewatch later. Many producers enjoy tuning in while working in the field.

FaRM Learning Hub

The FaRM (Farm Resilience Mentorship) Learning Hub is a go-to resource for Canadian farmers looking to build climate-resilient farms using regenerative agriculture practices. It offers self-guided learning modules, videos, and practical tools focused on grazing, soil health, and cover crops. The hub also features six free mini-courses that walk you through creating a grazing plan, covering key topics like paddock and cell design, fencing, record keeping, and more—perfect for getting started or refining your current system.

Ward Middleton

Ward and his wife, Jo-Anne Middleton, own and operate Midmore Farms in Sturgeon County, Alberta. Their operation has been certified organic for 28 years. The operation is an eclectic mixed farm that strives to find synergies between organic grain production and utilizing a custom grazing/feeding operation for nutrient import and soil health.
