Why analyse Iron? First, toxic, Non-chelated (free) Iron needs to be distinguished from the less dangerous Chelated form of Iron. Non-chelated Iron can be toxic at levels of 0.3mg/l and above. Second, Iron plant supplements need to be monitored to ensure safe levels. In Saltwater, ensure that a level of Iron does not reach a detectable reading. Natural ocean water contains an average of 0.001mg/l.
Importance of Iron for plants. Iron is an important component for proper metabolism in most terrestrial and aquatic plants. It is required for a number of enzyme controlled photosynthetic processes. Iron is also with plant respiration, chlorophyll synthesis and plant protein production. It is an essential element in the formation of plant cell membranes. Iron exists in two forms - Free (Non-chelated) and Chelated Iron. A good Iron supplement should be composed of Chelated Iron, as it is more easily assimilated by plants.
