A recurring series focusing on plant cultivation by university researchers. All plants require certain macro- and micronutrients to grow properly and complete their lifecycles. If one of these elements is lacking or overapplied, plant growth problems and tissue damage will occur, both above and below ground. When applying these necessary elements, it is important to hit the “sweet spot”—the optimal level for each nutrient. But looking at the overall nutrient levels in your crop is also important.
