Why is soil acidity important in gardening?
In order for their plants to thrive, gardeners and farmers need to be mindful of the acidity of the soil. Suppose you are planning a small garden for your neighborhood. Use the library or Internet to find out the typical soil acidity for your area and how this affects the variety of plant life. Talk to a local gardener, farmer, or plant nursery worker to find out how soil acidity is measured and maintained. Then write a paragraph that outlines your plan for the garden, making sure to discuss soil pH considerations.
