Iron (Fe) Nutrition of Plants (SL353/SS555)

iron deficiency in tomatoIron is one of 16 essential elements for plant growth and reproduction. Most annual plants have a requirement for Fe on the order of 1 to 1.5 lb Fe per acre, compared with nitrogen (N) at 80 to 200 lb per acre. This 8-page fact sheet provides a detailed basic understanding of soil science and plant physiology for diagnosing and correcting Fe problems in plants and soils.
