The present investigation was led during the year 2018-19 at Department of Soil Science and Agricultural Chemistry, M.S. Swaminathan School of Agriculture, Gajapati, Odisha with intend to consider supplement status of various village of Gosani square. The examples were gathered from various homesteads and towns of Gosani square. At that point test investigated according to standard strategy for surveying pH, EC, OC, and significant supplements like accessible nitrogen, phosphorous and potassium with micronutrients like zinc, copper, manganese and iron status of soils. The pH of soils changed from 6.13 to 6.44 and EC shifted from 0.06 to 0.34 dS/m. The natural carbon content in ranch soils was shifted from 0.35 to 0.55%. The accessible nitrogen, phosphorous and potassium ran from 125 to 250 and 31 to 41 and 185 to 542 kg/ha individually. The accessible zinc, copper, manganese and iron went from 1.08 to 2.92, 0.90 to 3.06, 9.96 to 27.90 and 17.02 to 74.14 mg/kg individually. The outcomes demonstrate that result were somewhat acidic in response, non-saline and low in natural carbon. The results were low to medium in accessible nitrogen and high in accessible phosphorous and medium to high in accessible potassium. The micronutrient status like accessible zinc was low to satisfactory and accessible copper, manganese; iron were sufficient sum found in soils. The outcomes presume that decent use of supplements required for fruitful harvest creation and advancement of vegetable in various villages under Gosani Block.
The Gajapati district comes under “North Eastern Ghat Agro Climatic Zone” with light textured brown forest soil, which is highly acidic in nature. The geographical situation of the district is characterized by undulated topography with hilly terrain where the rain water is carried through hill streams & nallas in seven tribal blocks.
Most part of Gajapati district is covered with rugged forest and mountainous terrain of Eastern Ghats rocks with narrow inter mountain valleys. The average elevation of hills ranges from 500 to 1200 m above mean sea level. The important hills in the district are Dandamera Parbat (1103m), Tangiri Parbat (1155 m) and Mahendra Giri (1499 m). The area in and around Mohana, Chandragiri, Chandiput and Parlakhemundi constitute the pediment of undulating plains which have undergone ineightse weathering. Vansadhara River along with its tributaries e.g. Harbahangi, Badanadi & Mahendra Tanaya etc controls the overall drainage of the district which displays a dendritic patter.
The soil characteristics of the district show wide variation according to their physical and chemical properties, mode of origin & occurrences. Soils are having average to good fertility status.
The area goes under “North Eastern Ghat Agro Climatic Zone” with light finished darker backwoods soil, which is profoundly acidic in nature (98% of soils are acidic in nature), The area of this region is restricted to Longitude 83 degree 48’ to 84 degree 7’ E and Latitude18 degree 46’ to 19 degree 9’ N, between Gopalpur (Odisha) to Kalingapatanam (AP) inside 48 km to 95 km from Sea shore (Sea coast). The topographical circumstance of the region is described by undulated geography with bumpy landscape where the downpour water is helped through slope streams and
Alfisols or Red soil incorporate red sandy soils and red loamy soils of which red sandy soils are prominently accessible is practically all squares aside from in Parlakhemundi square which is described by red loamy soils. Alfisols are unbiased to marginally basic in nature having light surface permeable and friable structure without lime kankars. These are lacking in nitrogen, phosphate, natural issue and lime and are useful for paddy crops.
Entisols or Alluvial soil is more youthful in source inadequate in nitrogen, phosphoric corrosive and nearly wealthy in potash, lime and metal, antacid is nature. These are the most common type soils in the area.
Soil sampling grids of one sample/5km2areas were pre-determined systematically for each community block from revenue map. Twenty five numbers of surface soil samples collected from each block and sampling was done with the help of GPS (Global positioning system) instrument. Latitude and Longitude recorded for each soil sample. The soil samples were collected from 15 cm depth (Muhr
A V-shaped cut made up to the plough layer and a uniform 1.5 cm thick slice taken out. The collected soil sample thoroughly mixed on a clean piece of polythene sheet, processed and kept it in plastic bottle with suitable description and identification code numbers.
Collected samples were brought to the laboratory spread out on paper. Leaves, Coarse concretions, stones, pieces of roots, and other un-decomposed organic residues were removed. Large lumps of moist soil were broken by hand. Samples were air dried at 20-25oC and 20% to 60% relative humidity inside the laboratory under shade. Samples were mixed during drying to expose bottom layer to top. After air drying soil samples were crushed gently with help of a wooden hammer and sieved through a 2 mm sieve. The material larger than 2 mm was discarded. They were stored with proper labelling in polythene bottles for analysis of physical, chemical & other properties.
The soil samples were analyzed for the physical &chemical properties i.e. Soil pH, electrical conductivity, organic carbon, and available nutrient (N, P, K, Fe, Mn, Cu and Zn).
Methods adopted for soil analysis
The pH of the soils ranges from 6.13 to 6.80 (
Electrical conductivity (EC) of different soil tests of natural ranch were ranges from 0.06 to 0.47dS m-1 with mean estimation of 0.20 dS m-1. The outcomes showed that every one of the soils are ordinary in nature and reasonable for a wide range of yields and for sound plant development because of the soils are liberated from saltiness. Comparable outcomes were also reviewed by Padole and Mahajan (2003) in swell-shrink soils of Vidharbha region.
Percentage of SOC content of the soils ranges from 0.32 to 0.55 (

Macro and micronutrient status in Gosani block
From the above investigation it was discovered that the soils were somewhat acidic (100%) and non-saline (100%). Soil natural carbon (SOC) substance of the examination territory was seen as low (70%), medium range (30%). Whole examination zone was seen as low in soil accessible nitrogen content (100%). The soils accessible phosphorus was seen as high (40%), medium (60%). Accessible potassium was seen as high range (100%). Whole examination zone was seen as medium to high in accessible micronutrient content. Hence, 25 per cent more fertilizers than that of the recommended dose should be applied in the soil having lower range of nutrients. In case of the soil of the village having higher status of nutrients, 25 per cent less fertilizers than that of the recommended dose should be applied. In the rest of the villages having medium range, recommended dose of fertilizers should be applied.
