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.
A lot of emphasis is put on the pH of garden soil. Soil pH is a measurement of the alkalinity or acidity of soil. Soil pH is measured on a scale of 1-14, with 7 as the neutral mark. Anything below 7 is considered acidic, or sour, soil and anything above 7 considered alkaline or sweet, soil.
