Soil Fertility Status of Some Villages in Khordha and Bhubaneswar Block of Khordha District under North Eastern Ghat Agro Climatic Zone of Odisha, India

Abstract

A soil fertility status inventory work was carried out in some villages of Khordha and Bhubaneswar blocks belonging to Khordha district located in the North-Eastern Ghats Agro Climatic Zone of Odisha, India. Results show that soil texture of the villages under investigation varied from loamy sand to clay loam. Clay content varied from 2.4 to 34.0 percent. Soil pH ranged between 4.24 and 6.93 and electrical conductivity of the entire study area remained below 1 dSm -1 . Soil Organic Carbon (SOC) content ranged between 1.1 to 11.6 g kg -1 . Available nitrogen content in these soils was found to be varying between 50.0 to 225.0 kg ha -1 . Available Bray"s phosphorus content varied from 11.3 to 2326.5 kg ha -1 . Available soil potassium content varied widely from 37.6 to 458.3 kg ha -1 . CaCl 2 extractable soil sulphur varied from 2.17 to 11.02 mg kg -1 . Hot water soluble boron content ranged from 0.91 to 2.68 mg kg -1 . All the figures in lower range were found in upland soils while the higher values for all the parameters were found in low land soils.

“…In the entire study area organic carbon status was found to be low to high which enables the soil for growing a wide range of crops. Similar findings have also been reported by Mishra (2013) [13] , Digal et al, (2018) [8] , Swain et al, (2019) [24] .…”

GPS based sampling for determination of fertility status of some villages of Jatani block of khordha district, Odisha

“…Prevalence of humid climate featured with high rain fall which contribute to leaching out of salts may be the probable reason of the less salinity of soils which make them fit for cultivation of all types of crop. Similar observations are seen in findings reported by Swain et al (2019) [22] .…”

“…Hence, soil acidity appears to be a major crop production constraint in the study area. Similar findings have also been reported earlier by Priyadarshini et al, (2017) [24] , Dash et al, (2018) [7] Swain et al, (2019) [27] and Mohapatra et al, (2020) [18] .…”

“…Soil organic carbon is significantly and positively correlated with N (r=0.99**), K (r=0.73**), Fe (r=0.57*) and Mn (r=0.78**) (Table 4). Similar findings have also been reported by Mishra (2013) [14] , Digal et al, (2018) [8] , Swain et al, (2019) [27] and Mohapatra et al, (2020) [18] .…”
