High Iron in Soils

Flowers and trees need a certain level of iron to grow well.

Plants need a certain amount of iron to grow and thrive. Iron levels aid the chemical process, which creates optimum performance in plants and trees. The level of iron in soil is important to prevent them from weakening or even dying.

Significance

Reduced fruit and flower production, stunted growth and toxic iron buildup are common problems for vegetation in high-iron level soil.

Function

Iron serves to help plants and trees with photosynthesis to produce chlorophyll and energy. Without iron, the plants are unable to properly use all of the nutrients needed for photosynthesis. The proper balance of iron enables plants to thrive.

Geography

Areas that are predominantly saturated with water or contain low levels of zinc contain high-iron soils. Areas around water tables are susceptible to high iron levels.

Identification

New or young plants display stunted growth, deep brown or purple leaves and stunted root growth, when there is a high concentration of iron in the soil.

Prevention/Solution

Add mulch and proper drainage to soil areas to reduce iron buildup. Increase soil acidity by adding organic materials or zinc to prevent iron buildup.
