The soil pH is a measure of the acidity or alkalinity in soils. A pH level below 7 is acidic and above 7 is alkaline.

Adding manure is the best way to make your soil acidic. Manure not only lowers soil pH but also provides other necessary components, add microorganisms and good insects, it improves soil texture, makes it porous, require for healthy plant growth.

If your soil is Acidic then wood ash is the best option for you to increase soil pH. Wood ash also contains potassium that is used by plants for fruit production. It is good for vegetables and fruits. However, there are things to remember before using it. Don’t use cardboard ash. Do not use wood ash with urea because it releases ammonia gas in contact with wood ash. Do not use it in the soil where you sowed seeds.

2. Limestone

  • Don’t apply any of these at the same time with a fertilizer in the same spreader.
  • If you are not sure about the exact level of your soil pH, don’t add too much quantity of any of the contents.
  • Areas that receive good rainfall and have cold climate have slightly acidic to acidic soil.
  • Areas having less rainfall, remains dry or come under tropics have neutral to alkaline soil.
