    4 Key Soil Types Advantages and Disadvantages

    Aug 27, 2020 Sandy Soil Advantages and Disadvantages. Sandy soils are light and gritty to the touch. Because sandy soils have large particles, they dry out quickly, are often low in nutrients and acidic. Both water and fertilizer have a tendency to leach out of the soil - escaping to waterways before the plant can utilize them. Advantages of Sandy Soils
