Air space in the soil is just as important for healthy roots as water. As your vegetables grow they will need more and more nutrients and water, and more air spaces for their roots to fill. It is vital to create a “soft” deep soil that your hand can penetrate as if pushing through sand. Sandy soil also benefits from compost to slow down drainage and leaching of nutrients.
