It is known that if there is not enough amount of a nutrient in the soil to meet the plants demand, that nutrient acts as a limiting agent and limits the development of the plant. Nutrients are divided into two; macro and micro elements. Macro elements are needed in greater amounts than micro elements. This experiment was aiming to show how the increasing iron in soil affected biomass of plant and to see, since iron is a micro element too, if it would make a significant difference. Iron is used in chlorophyll synthesis which is found in chloroplast, the organelle that contributes to increase in biomass of the plant, deficiency of iron causes chlorosis in leaves where they appear yellowish instead of green. There were 5 different groups which represent different iron contents in soil and 5 pots for every group, each pot containing two maize plants. The experiment showed that the relation between iron amount and biomass is significant. The highest biomass was observed when maximum amount of iron was applied which is 40 ppm, the minimum biomass was observed when no iron was applied. The percentage difference between maximum and minimum biomass is 18%. Generally low standard errors make the obtained data very reliable and the results are consistent with other similar works done before. From the results of this experiment, it can easily be said that as the iron content in soil increases, biomass of the plants increase as well, the most probable cause of this being increased chloroplast number.
