Online published on 10 July, 2023. Abstract Soil fertility and plant nutrition, both are governed by criteria of essentiality (Arnon and Stout in 1939 and further modified by Arnon in 1954). Earlier there were 16 essential elements and now it is 17. Researchers, policymakers and farmers mostly concerned themselves for the primary nutrients i.e. NPK to manage the crops and it further aggravate the deficiency of micronutrients which is now major concern for all because it is affecting human and animal nutrition along with plants. This deficiency is concerns not only the plant nutrition but has far reaching implication in form of nutritional insecurity among the livestock and marginal section of population. Thus it is important to study the importance of the micronutrients to take care these challenges and the management of micronutrients in crop production is based on their spatial distribution. Therefore, an attempt has been made to summarize importance of micronutrients for crop production according to their spatial distribution in India.
