Soil plays a significant role in determining the sustainable productivity of an agro ecosystem. It is one of the essential sources of micronutrients for plants. Out of the 16 essential nutrients, Zinc (Zn), Copper (Cu), Iodine (I), Manganese (Mn), Molybdenum (Mo), Boron (B) and Iron (Fe) are referred micronutrients. These micronutrients are required in small quantities but have agronomic importance as they play are vital in the growth and development of plants (Ye et al., 2015). Crop yield will be affected if any of these elements are lacking or excessive in the soil with other nutrients. Micronutrient deficiencies are alarmingly increased across the globe and further aggravated by many new cultivars as they are highly sensitive to micronutrient deficiency. Soils widely vary in micronutrient content and supply ability for optimal crop growth. soil's total micronutrient content is determined by the original geologic substrate and subsequent geochemical and pedogenic regimes. However, the total content is rarely indicative of available micronutrients as they depend on soil pH, organic matter content, surface area, and other physical, chemical, and biological conditions in the rhizosphere (Srinivasan et al., 2021). |
