A 2021 study revealed that interest in organic soil amendments like calcified seaweed has increased by nearly 30% among home gardeners. This natural, coral-like soil conditioner works to balance pH, improve structure, and supply vital trace elements for better plant health.

According to soil scientists, clay soil can have a cation exchange capacity (CEC) over 50% higher than sandy soil, making it far more fertile. This inherent ability to retain essential minerals is the primary reason why clay can hold a lot of nutrients, offering a significant advantage for gardeners and farmers who know how to manage it effectively.

A 2017 study found that over half of pregnant participants in South Africa engaged in geophagia. This practice raises the question: is clay dirt healthy, or are the risks too great?
