We present the nanometric chemical decomposition of Himalayan agricultural soils. The motivation to use this state-of-the-art material characterisation in the soil is to reduce the testing cost while increasing the efficiency of the characterisation. In India, a bulk volume of soil is still required for the characterisation of agricultural soil. The fertility of micronutrient contents and crop supply capacity vary greatly depending on soil types, crop types, ecology, and agroclimatic variability. Since total levels of micronutrients are rarely predictive of the availability of a nutrient to plants, knowledge of the differences in soil micronutrients that are available to plants is essential for the sensible management of micronutrient fertility and toxicity. In the state of Uttarakhand, low levels of micro-nutrients in the soil are frighteningly common, and this issue is made worse by the fact that many current cultivars of important crops are extremely vulnerable to low mineral levels. These baseline results are to be used to inform local farmers about the potential remedies, costs, and consequential benefits and durability. We intend not to present a generalized or generalized solution. Therefore, we limit our soil sample collections to five arc minutes (8.6 square kilometers) and document variations and heterogeneity in the chemical components of the soil. In this study, we used scanning electron microscopy to chemically deconstruct the barren Himalayan soils from Uttarakhand. Aluminium, carbon, oxygen, and silicon were identified as the primary elements that contributed more than 5% of the total weight and atomic percentage. Other elements include less than 4% of iron, titanium, nitrogen, sodium, magnesium, chloride, phosphorus, sulfur, potassium, and calcium.
