“…Like sulphur status, available boron status is also closely followed by organic carbon status in these soils (Harshita, 2018) [3] . A similar result was reported by Gurumurthy et al (2019) [2] .…”

An assessment on fertility status was carried out on the soils of Nandipura micro-watershed during the year 2018-2019. Forty-eight grid samples were collected and analysed for its fertility status and were mapped using ArcGIS software. The mapping of fertility status of soils of Nandipura micro-watershed revealed that the soils were low (86.52% of the micro-watershed area) to medium (8.57%) in available nitrogen content, low (44.02%) to medium (51.07%) in available phosphorus, low (15.20%) to medium (79.89%) in available potassium, medium (21.56%) to high (73.52%) in available sulphur, exchangeable calcium and magnesium content were sufficient in entire micro-watershed area. DTPA extractable zinc was deficient in 105 ha and sufficient in 370 ha area whereas, DTPA extractable iron, copper and manganese were sufficient throughout the study area. Available boron was low (34.38%) to medium (60.25%).

“…The highest content of available phosphorous was noticed in Novinihal series due to higher CEC and clay content. The available phosphorus content showed the decreasing trend with soil depth which was attributed to its higher removal than replenishment in sub-surface horizons and also higher fixation of phosphorous as discussed by Sathish and Badrinath (1994) and Gurumurthy et al (2019). Higher content of available potassium was seen in the surface layer and showed more or less a decreasing trend with solum depth due to rapid weathering of rocks, release of labile K from organic residues, application of potash fertilizers and upward movement of potassium from lower depths along with capillary rise of ground water as observed by Rajeshwar and Mani (2013) The highest (13.40 ppm) amount of sulphur was seen in Novinihal series, while the lowest (6.7 ppm) in Margutti (P-2) series (Table 6).…”

Aim: To evaluate the soils of Malli-1 micro watershed situated in the North-Eastern Dry Zone (Zone-2) of Karnataka for sustainable crop development. Methodology: Eight soil profiles covering all soil types occurred in the study area were selected and studied for their detailed morphological, physical and chemical properties using standard soil testing procedures. Results: Soils of Malli-1 microwatershed varied from clay to clay loam in texture, moderately to strongly alkaline in reaction with low salt content and low to medium in per cent organic carbon content. Calcium and magnesium were the prevailing cations followed by sodium and potassium. Soils were classified upto the series level as per revisions in Soil Taxonomy by utilizing soil characteristics. Majority of soils in study area represents the Vertisols, Inceptisols and Entisols order. Interpretation: These results indicate that soils were less fertile due to deficit in soil nutrients. Recommended doses of organic bio-fertilizer and inorganic fertilizer should be practiced for reclamation of soil status. Key words: Electro chemical stability index, microwatershed, Soil resources, Soil survey

“…Similar result was found by Riyabati and Sarangthem (2017) [40] ; Khadka et al, (2017) [22] , Vijaya et al (2000) [51] . Higher available manganese may be present in the study site soil due to granite gneiss parent material (Gurumurthy et al, 2019 [17] , Katti et al, 2020) [21] .…”
