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.

Guest bio

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.
