or too low, plants will not be akle to effectively use fertilizer nutrients. This nwiw fertilizers are wasted when the proper soil pH is not maintained.
Many plants grow mB over a wide range of sod pH as long as other growing cooditkns are ideal. Soane plants, however, grow best within a narrow pH range.
lire sail pH test kit is an easy way to determine if a soil is acidic, neutral or alt»W Hie pH scale is much like readh^ a thermometer with the range of alkaline and acidic material* divided into 14 points.
Some plants (rhododendrons, anises, blueberries) Idee to grow in acidic sail with pH levels below 7.0. Most flowers, ornamental shrubs, trees, vegetables and turf grasses grow best in slightly acidic sails with a pH level between 6.1 and 6.9.
Ihe availability of most «■! nutrients is greatest at a pH near 6.5. When pH rises above this level, trace elements such ns iron, manganese, copper and zinc became less available to plants. When the pH level tolls bdow 6^5, calcium and molybdenum became less available. When to sample soO
