Healthy soil is a living, breathing ecosystem full of microbes and nutrients that feed your plants. “The Big Three” nutrients are Nitrogen, Phosphorus and Potassium, which is the N-P-K you see on a bag of fertilizer. But the big three need helpers, like calcium, magnesium, and iron. The microbes in soil are an invisible workforce that makes all the nutrients “edible” for the roots. These microbes include beneficial bacteria, which fixes the soils nitrogen using the air, and mycorrhizal fungi, which is the roots extension service..it reaches out into the soil to grab water and phosphorus, and brings it to the plant.
