Don’t guess, soil test. Soil testing has a long history on farms across Canada and is one of the most important management practices any operation can make to improve yields, profitability and reduce environmental impacts.
In most regions of the country, soil tests are completed in each field every three or four years, primarily to monitor phosphorus (P) and potassium (K) levels, as well as key soil metrics that include pH, cation exchange capacity (CEC) and organic matter. More recent options include soil nitrate tests to estimate levels of available N, which is especially useful to maximize nutrient use efficiency in regions with significant precipitation.
