How can I make my soil fertile?

Make sure your nutrient balance is right Most plants thrive only when the soil has the right balance of acidity and alkalinity. If the soil is too acidic, or below 5.5 on a soil pH scale, you’ll need to add ground limestone. If it’s too alkaline, more than 7.5 on the pH scale, you should add soil sulfur.
