Silt loam soils will benefit from composted manure, composted vegetable matter, ground and aged pine bark or a commercial soil conditioner. These amendments improve soil aeration, drainage and available nutrients.
Why is clay soil bad?
Clay soils are not always bad. They hold more water than sandy soils and are often high in nutrients plants need. But clay soils can become so waterlogged that they deprive plant roots of oxygen, or so dry that they become too hard to dig in.
What is the texture of silty soil?
Both silt and clay soils have a very smooth texture. It is very important to be able to tell the difference between these two soils because they may behave very differently when used as construction material for dams or dikes where the silt may not have enough plasticity.
Is clay soil high or low pH?
The pH of most clay soils will always be on the alkaline side of the scale, unlike sandy soils which tend to be more acidic. While the high pH of clay soil might be suitable for certain plant types like asters, switchgrass, and hostas, it is too alkaline for most other plants.
Is clay soil more acidic or alkaline?
Clay soil has a higher CEC count than sandy soil, meaning that it has more capacity to hold hydrogen ions, but not that it necessarily holds enough hydrogen ions to make it consistently acidic. Clay soil requires fewer chemicals to lower the pH than sandy soil does, making it appear more acidic.
What pH level is best for plants?
Vegetables, grasses and most ornamentals do best in slightly acidic soils (pH 5.8 to 6.5). Soil pH values above or below these ranges may result in less vigorous growth and nutrient deficiencies. Nutrients for healthy plant growth are divided into three categories: primary, secondary and micronutrients.

Clay Soils
Soils rich in clay and silt have the greatest potential to damage a foundation. Clay absorbs water easily, expanding in volume as it becomes more saturated. So-called “expansive clays” can cause foundations to crack, heave and shift.
Is clay or sand better for foundations?
