uptake. Nutrients in the soil are most readily available to plants when the soil pH is between 6.5 and 7. When soils are more acidic or more alkaline, the nutrients may be in the soil, but the soil pH makes it more difficult for plants to use those nutrients. Changing a soil's pH can be difficult, as changing the pH from 7 to 6 is ten times
