PH CONTROL

SOIL PH

• Is a measure of how acid or alkalinity is
• Is important because it influences how easily
• Soil plants can take up nutrients from the soil

REGIONAL DIFFERENCES

• There are many factors that affect ph.
• Some of them are rainfall, vegetation type, and more
• Regions with heavy rainfall have acidic soils.
• Light rain results in a more neutral soil.
• Ph is also affected by construction.

CHANGING PH

• Most garden plants grow well in slightly acid to neutral soil (pH 6.0-7.0)
• Except blueberries, potatoes, azaleas, and rhododendrons
• Which prefer moderately acid soil.

IMPORTANCE OF PH IN SOIL
