A Soil Primer

The basis for successful organic gardening is excellent soil. The better the soil, the better the plant. What is excellent soil? There are three aspects to defining soil: texture, structure, and porosity.
Soil texture is essentially the percentages of clay, sand, and silt. The National Gardening Association?s Gardening for Dummies has a simple test for approximating soil texture. Take a handful of moist soil and squeeze it into a ball. Work the soil into the shape of a ribbon by pressing and rolling it between your thumb and forefinger. Stand the ribbon straight up.
If you can?t make a ribbon without it falling apart, the soil is at least 50% by volume sand with very little clay. If the ribbon is much less that 2″ long before it breaks, the soil has about 25% clay. If the ribbon is between 2″ and 3.5″, it has about 40% clay. If it is still together and longer than 3.5″, then it is at least 50% clay.
