To attain high yields, crops require a balanced ratio of macronutrients (NPK – nitrogen, phosphorus and potassium) and micronutrients (zinc, copper, manganese, iron, boron, etc.) The correct amount of some nutrients and the limited supply of others can create imbalances and reduce yield potential.
However, the higher the yield a crop produces, the more nutrients it takes out of the soil. Today’s high-yielding crops remove more nutrients from the soil than ever, leading to issues of nutrient availability.
Weather also plays a part, with most micronutrients virtually unavailable in the cool/cold temperatures and wet soil conditions which are typical of spring across Western Canada. Using a liquid starter fertilizer at seeding time can help correct micronutrient deficiency in the soil, preventing common early-season deficiencies in crops and improving yields.
