Introducing Soil Test Manager

Have you ever looked up the official Ontario fertilizer or liming recommendations? They’re featured in “look-up” tables in OMAFRA production guides, such as our Agronomy Guide for Field Crops (Publication 811), and provide rates for phosphorus, potassium, magnesium, zinc and manganese, as well as lime, based on soil test values. A new way to access […]
