How to Test Sandy Soil
Determine whether or not your garden has sandy soil with these two simple steps.
Step 1: Test Soil
To determine whether your garden has sandy soil, and thus may need regular irrigation and boosting with organic matter, carry out a simple test to examine the texture of the soil. Take your sample from just below the soil surface and repeat at intervals across the garden to ensure an even overall result. Rub a small amount of soil between your fingers. If the soil has a gritty, granular feel, it is likely to contain a high proportion of sand.
Step 2: Squeeze Soil
Try to squeeze the soil into a ball—the grains of sandy soil will not stick together, but if it is loamy, the shape may hold a little.
