Cast iron plants can be sourced from your local nursery or, if you have the right connections, you can obtain some rhizome divisions from a friend, family member, or neighbor. Minnesota soils can supply some K for crop production, but when the supply from the soil isn't adequate, a fertilizer program must supply the K. Potassium for crop production | UMN Extension Fe 2+, on the other hand, is mobile and available to plants. On the other hand, iron deficiency in plants is known as chlorosis. Plants have evolved two different strategies (based on the type of species) namely reduction and chelation strategy for uptake of iron from the terrestrial environment (Zhang et al. Cast iron plant is a slow but steady grower that reaches a height of 2 feet (61 cm.) Abstract Zinc is an essential micronutrient that enters the plant primarily via absorption of Zn2+ from the soil solution by plant roots.

The deficiency aggravates under high alkalinity, high concentration of calcium carbonate, bicarbonate, phosphate, heavy metals, water logging and low temperature. Iron is found in the iron-containing (heme) proteins in plants, examples of which are the cytochromes. Copper is the main component of enzymes. Young leaves of fruit trees become chlorotic. At soil pH lower than 5.5, manganese toxicity might occur. If your soil is alkaline with a pH of higher than 6.5, then it is more likely that iron will not be available to the plant's roots for absorption. On the basis of intake data and isotope studies, iron bioavailability has been estimated to be in the range of 14-18% for mixed diets and 5-12% for vegetarian diets in subjects with no iron stores, and these values have been used to generate dietary reference values for all population groups.
