Wolkowski explains that the largest amounts of crushed wallboard raised concentrations of soil calcium and sulfur but lowered soil magnesium; the excess calcium from the wallboard displaces magnesium from the soil, allowing it to leach away. Alfalfa grown on magnesium-deficient soil could therefore become magnesium-depleted and potentially cause tetany if fed to cows (the muscular spasms and twitching of tetany result from insufficient minerals such as magnesium).
