Chlorosis is a condition in which leaves produce insufficient chlorophyll. As chlorophyll is responsible for the green colour of leaves, chlorotic leaves are pale, yellow or yellow-white. Chlorosis is typically caused when leaves do not have enough nutrients to synthesise all the chlorophyll they need. It can be brought about a combination of factors including a specific mineral deficiency in the soil, such as iron or magnesium.
The naturally occurring inorganic nutrient found in the soil and food that is necessary for the proper functioning of animal and plant bodies is defined as nutrition. Minerals are vital elements essential for the body.
