How does nutrients get locked up in the soil?
The mid-range of pH level, also know as sweet soil, is optimal for bacteria and this helps to decompose. This process releases the minerals and nutrients making them ready and available for your raised vegetable garden plants. Also, mid-range pH levels grow soil microorganisms that will convert nitrogen in the air into a form your raised vegetable garden plants can use. Testing pH in your raised vegetable garden soil should be frequent and a routine task. You can view a pH chart for your raised vegetable garden here.
