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.
Soil pH measures the acidity or alkalinity of a soil, with a pH below 7.0 indicating that the soil is acidic and a pH above 7.0 indicating alkaline conditions. Soil pH affects nutrient availability and thus can greatly influence plant health. Various types of tests are available for individual homeowners or growers to test the pH of their soil.
