Detailed explanation-1: -Plants grow best when the pH of soil is close to 7. Most nutrients that plants need can dissolve easily when the pH of the soil solution ranges from 6.0 to 7.5. Below pH 6.0, some nutrients, such as nitrogen, phosphorus, and potassium, are less available.
Detailed explanation-2: -In general, most plants grow best in a neutral soil pH, although there are important exceptions. For example, blueberries, azaleas and rhododendrons do well in an acidic soil between 4.5 and 5.5. Lawns favor a pH of 5.5 to 6. Roses do best in soils with a neutral pH of 6.5 to 7.
Detailed explanation-3: -It has been determined that most plant nutrients are optimally available to plants within this 6.5 to 7.5 pH range, plus this range of pH is generally very compatible to plant root growth.
Detailed explanation-4: -The best way to increase the pH in soil is using a lime-based compound such as dolomite lime and agricultural lime. However, other methods such as using baking soda, crushed eggshells, or wood ashes can also be used.
