New Hamburg Press Release

As I travel across Canada, it has been great to see moisture along much of my path. Greener pastures and ditches in Alberta, lush spring wheat, durum, and lentil crops in Saskatchewan, as well as many triticale, grass, and alfalfa fields, are being cut from British Columbia to Nova Scotia. I do not want to forget those potatoes spread across our country along with many specialty crops. As heat and moisture have brought germination, emergence, and vegetation growth, our crop nutrient management remains a key to success as we monitor the “Points of Influence.” Crop scouting, accompanied by tissue or sap samples, supports crop-based crop protection and foliar nutrient applications. As we have been programmed to concentrate on nitrogen, we are putting a lot of pressure on one nutrient to solve many deficiencies and concerns while ignoring the balance of fertility our crops may be looking for. In this blog post, I will not cover all the nutrient requirements but concentrate a little on magnesium, as I refer to what makes plants green. This spring, a significant amount of discussion surfaced around magnesium, and several growers requested magnesium for their cropping plans. Sometimes, what is new is old; looking back, magnesium has been a big part of many crop plans for decades. In sandy soils, specialty crops, and our high calcitic soils, we are looking to balance our oxygen and moisture space in soil levels. To better understand what we are looking at, I have included a list of what Mg is responsible for as well as soil activity stated: Magnesium Crops require magnesium to capture the sun's energy for growth and production through photosynthesis. Magnesium is an essential component of the chlorophyll molecule, with each molecule containing 6.7 percent magnesium. Magnesium also acts as a phosphorus carrier in plants. Necessary for cell division and protein formation. Phosphorus uptake could not occur without magnesium, and vice versa. Magnesium is essential for phosphate metabolism, plant respiration, and the activation of several enzyme systems.
