Magnesium, the Unheralded Star

Although nitrogen, phosphorus, potassium and even calcium are often discussed, magnesium is mostly unheralded and misunderstood. In this article I will examine the nature of magnesium deficiency and show how ignoring soil magnesium can lead to dire consequences in human, plant and animal health.

Unlike nitrogen, phosphorus and potassium, magnesium is often overlooked in conventional fertility.

Like the other aforementioned macrominerals, magnesium is essential for plant and animal health and productivity. In man, beasts and plants it is found in substantial amounts and can wreak havoc when it is deficient.

Our health is rooted in our soils both as vegetables we consume and as animal products, which are nourished from the soil. Since the vast majority of what we eat comes from the soil, our health partly depends on earthworm activity, but the overuse of modern chemical fertilizers and pesticides has left many soils deficient in earthworms. This in turn impoverishes the soil.

As soils lose their vibrant microbial activity they become depleted in critical nutrients even as fertilizers are applied in larger amounts. Synthetic fertilizers are not a solution and often aggravate soil issues they supposedly cure. Remedying this downward spiral is more critical than ever because a growing population needs not only more food but better food quality for present and future generations to thrive.

Soil Sentinels: Harness The Power of Earthworms

When moist, practically all soils from tundra to lowland tropics support the activity of earthworms. Largely unseen, earthworms are a diverse, powerful workforce with the capacity to transform soil into fertile ground.

Found in 27 families, more than 700 genera and greater than 7,000 species, earthworms vary from about 1 inch to 2 yards long. Their living mass outweighs all other animal life forms in global soils. Although we may view earthworms as being both prolific and productive, do we fully appreciate our human capability to favor their beneficial efforts as allies allowing farms and gardens to flourish? I think not.

Earthworms not only play productive roles in sustainable agriculture, but they have enormous capacity to help mitigate our elevated atmospheric greenhouse gas content by reducing carbon and nitrogen gas. Continue Reading →
