If an individual has a low white blood cell count, his or her body becomes susceptible to serious illnesses and infections. A low white blood cell count can indicate the presence of one or more serious health problems, such as leukemia, hyperthyroidism, aplastic anemia, or an infectious disease.
To test: add 2 teaspoons of garden soil to a jar and a few inches of cabbage water. Stir and wait for 30 minutes. Check the color. If it turns pink, your soil is acidic. If it is blue/green, your soil is alkaline. There are quite a few fruit and vegetable plants that thrive in acidic soil.
At the top end of the scale soil is basic. A neutral or slightly acidic pH is 6 to 7.5. Before you add amendments to the soil, you need to know the pH. A simple way to measure pH is by using paper pH testing strips. It's less expensive than sending out soil samples, and you get the results right away.
