Extensive studies on the nutrient effects of N, P, and S on crops have been studied over the past 35 years by scientists at the Melfort Research Station. Later work was devoted to micronutrients such as boron applied to canola. In the past 10 years, work with the micronutrients boron (B), copper (Cu), and zinc (Zn) on forage seed production has been undertaken. Soil test correlation, placement studies, fertilizer sources and timing of application of the macronutrients on several crops have been investigated over the years. Fertility work with forage crops on pasture and for seed production is presented here.
