We are of the soil and the soil is of us. There is great variation within these basic groups, but these categories will suffice for the purpose of describing where a given plant will grow. Sandy soils, referred to as light soils, contain large-sized soil particles that are loose and easy to work. They allow water to drain readily, and tend to be low in nutrients.
Sandy soils tend to be more acidic than the more fertile loams and clays.
If your soil's pH is below 5, consider adding lime or wood ashes to raise the pH to 6 or 7. Clay soils are known as heavy soils. Consisting of small, tightly packed soil particles, clays tend to be dense and hard to work. They're generally rich in nutrients, have a high water-holding capacity, and can be very productive. Easier to work than clays, better consolidated than sands, loamy soils are an excellent growing medium.
