Abstract:

A survey was conducted to map the micro-secondary nutrient status of surface and subsurface soils of pulse growing region of Ganjam to find out the soil related production constraint for pulse growing region of Ganjam district of Odisha where pulses are grown in an area of 20.8 lakh ha with a low production and productivity. For the study GPS based 565 surface samples from 22 blocks of Ganjam district and two pedons (one each from upland and medium land) were collected during dry season, studied in the field and laboratory following standard procedures. The surface soils of Ganjam district were mostly acidic in reaction and non saline. The organic carbon content varied from 0.01 to 1.64% with 39.82 PSD. The exchangeable calcium and magnesium content varied from 1.08 to 10.80 cmole (p+)/kg and 0.02 to 5.76 cmole (p+)/kg. The available sulphur content ranged from 0.25 to 130.60 mg/kg with 48.08 PSD. The DTPA extractable Fe, Mn, Cu ranged from 6.33 to 315.76, 2.28 to 255.76 and 0.02 to 8.32 mg/kg respectively. The DTPA extractable Zn content varied from 0.02 to 19.21 mg/kg with 31.36 PSD. The HWS-B content varied from 0.02-11.3 mg/kg with 52.54 PSD. Multinutrient deficiency of S+B, B+Zn, S+Zn and S+B+Zn was 26.55, 18.76, 18.05 and 10.97 per cent respectively. GIS based fertility maps for pH, S, Fe, Mn, Cu, Zn and B were prepared on the basis of standard rating. From the above study for better management and to enhance the production, productivity and quality nutrient rich pulse crops in Ganjam soils application of lime, S, Zn & B nutrient should be supplemented Proper rates of lime, S, Zn and B should be applied to the pulse growing soils of Ganjam to boost its productivity. Further correlation of soil test data with various soil properties were.
