A detailed soil survey was carried out in Valapadi block of Salem district consists of 39 villages spread over 18551 hectares. Based on variation in physiography and landform, ten soil series and 57 soil mapping units were identified. Ten typifying pedons representing the soil series were analysed for its physico -chemical properties and characterized for mapping. Soils are deep to very deep, well drained to somewhat poorly drained, light to dark coloured, light to heavy textured. pH of soils ranged from 6.3 to 8.9 with mean value of 7.8, EC ranged between 0.1 to 0.5 dSm -1 , OC varied from 0.11 to 0.68% with mean value of 0.33%, CEC ranged from 8.5 to 27.4 cmol (p+) kg -1 with mean value of 17.87 cmol (p+) kg -1 . The land capability classification in the study area indicates that moderately good cultivated soils covered 18.6 percent area was affected with moderate limitations of erosion, where as the extent of moderate limitations of erosion and calcareousness was 65.9 percent. The land irrigability groupings indicate that about 18.6 percent area of the block may be used safely under irrigation. The erosion and calcareousness land covering 65.9 percent of the area were moderately suitable for sustained use under irrigation, provided proper soil and water conservation measures to be adopted.

“…Organic carbon content varied from 0.1 to 1.16%. The enrichment of OC content in surface soils are high could be plant dry matter and root biomass accumulation (Balasubramanian et al, 2020) [3] . Low OC content indicated poor nutrient management and high removal of crops (Srinivasan et al, 2017) [13] .…”

Coleus is a perennial herb with fleshy, fibrous roots and grows wild in the warm sub-tropical temperate areas in India. In Ayurvedic Medicine it has been used for over 3,000 years to treat heart and lung diseases. In India it has been cultivated for a long time as an important medicinal plant because of its unique diterpenoid content. In recent years the plant has gained pharmacological importance as the only known plant source of the adenylate cyclase activating compound. Detailed soil characterization was carried out in different yield rating (low, medium and high) zones in two Agro climatic zones of (North Eastern and Hill area zones) of Tamil Nadu to assessing the yield limiting soil factors. Typifying soil profiles and surface samples were collected from representing agro climatic zones and soils were analysed. Soils are shallow to deep, well to somewhat poorly drained, dark brown to dark reddish brown in moist colour. The soils were sandy clay loam to sandy clay and clay content ranged from 28 to 45%. The organic carbon in soils ranged from 0.10 to 1.16% and cation exchange capacity from 8.2 to 16.6 cmol (p + ) kg -1 soil, respectively. Soils were low in available nitrogen, low to medium in available phosphorus and low to medium in available potassium. In general, soils were deficient in DTPAextractable Zn and other micro nutrients like copper, iron and manganese are sufficient. Plant characteristics of different climatic zones were shows significant with soil depth and other characteristics.

“…Soil characterization is done by analysing and comparing the properties of soil from one to another area of study. As the soil forming processes changes it leads to changes in soil properties in different area or agro-ecological zones so that it's dynamic in nature [1][2][3].…”

A comprehensive soil analysis was conducted in the Western and North-Western regions, encompassing four districts: Coimbatore, Tiruppur, Erode and Salem in Tamil Nadu, India. Owing to differences in topography and terrain features, seven distinct soil series i.e. Somayanur, Ammapettai, Palathurai, Tulukkanur, Yethapur, Suramangalam and Salem were recognized. Seven representative pedons were examined for their morphological, physical and physico-chemical attributes. The soils range from shallow to profoundly deep, with drainage varying from well-drained to poorly drained. When moist, they exhibit a hue from light brown to dark red to dark brown and when dry light brown to light yellowish brown. Soils have textures spanning from light (sandy loam) to heavy (silty clay). The pH values ranged from 6.2 to 8.92 in water, 5.41 to 7.68 in CaCl2 and 5.65 to 7.89 in KCl, Electrical conductivity (EC) varied between 0.11 and 0.41 dS m-1, organic carbon content was between 1.2 g.kg-1 and 9.6 g.kg-1, cation exchange capacity varies from 5.60 to 30.80 cmol(p+).kg-1, base saturation percentage and exchangeable sodium percentage varies from 81.0 to 98.2% and 0.37 to 3.88%. Free calcium carbonate of soil ranges from 0 to 10 % which indicates non-calcareous to calcareous nature of soils. Implementing suitable site-specific technologies is essential for attaining sustainable productivity of the soils of Western and North-Western Zones of Tamil Nadu.
