What your Soil Texture Test Results Mean

• Soil that has a high percentage of sand (70 percent or more) tends to be well aerated, ready to plant earlier in spring. But it also tends to need more frequent watering and fertilization than heavier soils.

• Soil that has 35 percent or more clay retains moisture well, so it takes longer to dry in spring and may need less watering in summer. It can be richer and is more likely to produce lush growth with just the addition of compost and, occasionally, a little fertilizer. The compost is important. It helps break up clay so the soil won’t be too dense and poorly aerated.

• Soil that has nearly equal percentages of sand, silt, and clay can have intermediate characteristics and is generally well suited for good gardening.
