Detailed explanation-1: -The pH is important because it influences the availability of essential nutrients. Most horticultural crops will grow satisfactorily in soils having a pH between 6 (slightly acid) and 7.5 (slightly alkaline). Since most garden soils in Iowa are in this range, most gardeners experience few problems with soil pH.
Detailed explanation-2: -A meter and probe or litmus paper can be used to measure the pH of a sample. The more accurate, but expensive, of these methods is the meter and probe. pH meters are calibrated using special solutions, or buffers with a known pH value.
Detailed explanation-3: -Why is soil pH important in gardening? A soil’s pH is directly connected to its concentration of major nutrients, as well as its composition of microelements available for uptake by plants. When soil pH is extremely high or low, the plants growing in it may suffer from nutrient deficiencies or toxicities.
