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.
Before attempting to change your soilâs pH, you must know its current level. This will determine how much you need to raise or lower it, if at all. A simple soil test can be done at home or by a soil-testing laboratory. You must also know your soilâs texture, be it clay, sand, or something in between. More material is needed to change the pH level of a clay soil than for a sandy soil because the charged surfaces of clays make them more resistant to pH changes than the uncharged surfaces of sand particles.
