How to determine soil type?
Its great to discuss the advantage of loamy soil, but how can a gardener or farmer determine their soil type easily and inexpensively.
Many gardeners, however, learn to estimate the content of their soil by feel. To get an idea of your soil type, pick up a handful of slightly damp soil and squeeze it tightly in your fist to form a ball; then, open your hand and observe the results.
Sandy soils will not hold together, will feel coarse to the touch, and will sift through the fingers of your hand.
Clay soils will form a hard ball when you compress them in your hand. Come back later and the ball will still hold its shape.
Silty soils will form a loose ball when you put them in your hand. If you let the ball dry, the remaining soil will crumble when you come back later.
From the article – Loamy soil forms a soft ball that will crumble if you press it with your finger. When dry, the ball will break apart easily.
