Iron Deficiency Chlorosis on Woody Landscape Plants in Wyoming (Publication #B-1097)
Soils in the Rocky Mountain West developed under arid conditions from materials that contain limestone. These soils are high in free lime (calcium carbonate), which causes them to alkaline. Other factors that are products of area climate and geology sometimes limit the availability of certain soil nutrients and cause nutrient deficiencies. Iron Deficiency Chlorosis on Woody Landscape Plants in Wyoming is a 4-page bulletin that explains the most common factor of these soil characteristics: iron deficiency. Iron is one of 16 chemical elements essential for plant growth and is required by plants in small amounts. However, its availability is greatly influenced by soil conditions. Causes of iron deficiency are discussed in this bulletin, along with symptoms and prevention and treatment methods. According to the authors, "The best strategy for preventing iron deficiency chlorosis is the proper selection of plant material. Plant species differ widely in their tolerance of soil conditions that cause iron deficiency."
