Soil Fertility
The Soil Fertility Guide provides a thorough overview of everything you should consider when assessing nutrient needs. Other pages deal with specific fertility challenges and new fertility-boosting options.
Restriction on Winter Application of Nutrients
Provincial legislation prohibits the application of nitrogen and phosphorus between and including November 10 of one year and April 10 of the following year. However depending on weather conditions variances may be issued.
