Micronutrients are crucial to the health of plants and crops

Every plant requires micronutrients. These must be available in the correct proportions and must be administered at the right intervals. The less well-known trace elements, such as iron, manganese, zinc, copper, magnesium etc. play a crucial part as micronutrient. While specific needs vary according to climate, soil, technical measures adopted and choice of crop, it is vital that the proper balance is maintained.

The main function of chelating agenst is to deliver micronutrients to the plant. However, they also have other important benefits, like resistance to micro-organisms. Furthermore they considerably increase the solubility of micronutrients, facilitating their transport to the root surface and ensuring their ready availability even in lime-rich alkaline soils. Absorption by the plant is easier and swifter, resulting in rapid recovery from deficiencies. Additionally since nearly all of the micronutrients administered are absorbed, lower dosages are needed compared to inorganic salts.

Hidden Hunger

If a plant lacks any of the micronutrients it requires, its development, growth and/or reproduction will be affected, resulting in lower yields. This may not always be apparent. A plant may suffer from micronutrient malnutrition long before any symptoms become evident. Such a plant may appear healthy, but the quality and quantity of the crop will be adversely affected.
