1. Soil pH

Soil acidity and alkalinity affect nutrient availability in the soil to the plant roots. Depending upon the plant, if the soil pH is too acid or too alkaline, then nutrients uptake is likely to be low and symptoms of nutrient deficiencies will appear. A measurement of soil pH is recommended before you work the soil. The soil pH is an important test for all soils. Acid-forming and liming materials will be recommended when the pH is out of optimum range for good growth. This test provides useful information especially for acid-loving plants like rhododendrons, blueberries, heather, gardenias, evergreen trees and shrubs. Soil pH readings should be part of a monitoring plan after initiating any corrections with sulfur or lime; included with every test kit offered. Avid gardeners and landscape managers should also consider purchasing a portable pH meter to keep track of how amendments affect the pH over time.
