Calcium: The Trucker of All Nutrients
First, we need to start in the soil. Calcium has many roles in the soil. Calcium aids in maintaining soil physical properties, and in reclaiming sodic soils. Calcium contributes to soil fertility by helping maintain a flocculated clay and therefore provides more aeration. Soil structure and water holding capacity are improved when soils are rich in calcium. Calcium also stimulates the growth of beneficial soil microorganisms, including nitrogen-fixing bacteria, and helps counteract toxins in the soil and in the plant.
