What role does sand play in determining soil fertility? Sand particles have a small surface area relative to their mass, meaning they do not hold on to nutrients well. Clay particles have a large surface area relative to their mass, so a small amount of clay can add a significant amount of surface area to a soil, increasing the nutrient-holding capacity.
