Most of the surveyed area is under rainfedcultivation. 2. Total 49 soil series are found in the survey area. 3. Majority of the area isgently terraced sloping (3-5%), 11934 ha (31.49%) followed by very gently terraced sloping (1-3%), 10743ha (28.35%), very gently sloping (1-3%), 5368 ha (14.16%) and gently sloping (3-5%), 4745 ha (12.52%). 4. Most of the area is affected by none to slight erosion 22677 ha (59.84%) which are mostly under cultivation followed by moderate erosion 8926 ha (23.55%) and severe erosion 2704 ha (7.14%) respectively. 5. Nearly 22389 ha(59.08%) area is well managed and covered under agriculture (rainfed) which needs assured irrigation besides effective agronomic practices. 6. Most of the soils in the surveyed area are very deep covering 12680 ha.(33.46%) followed by shallow 8122 ha.(21.43%), deep 7163 ha.(18.90%) and moderately deep 6342 ha. (16.73). 7. Soils of the area are taxonomically classified into three orders i.e. Alfisol, Inceptisols and Entisol. All the 49soils series identified in the area are further classified into 7 sub-orders, 10 great groups, 19 subgroups and 33 families. 8. Soils of the area shows acidic in nature, free from salt hazards, low organic carbon content and low value of CEC which indicates low fertility status. 9. Application of recommended doses of balanced fertilizer and manures besides a assured irrigation needed for sustained agriculture production. 10. Integrated watershed management plan is highly recommended in this rainfed area for overall agriculture development. iv How to Use Soil Survey Report The present report furnishes a detailed account of various characteristics of the surveyed area like physiography, relief, geology, climate, natural vegetation, land use and soils. Detailed description of soil series recognized in the area and interpretation of different soil mapping units for various applied aspects of agricultural development, such as land use planning, soil and water management, soil conservation, are given in relevant chapters. Different problems of the area have been depicted and corrective measures have also been suggested. In order to use the report, the user may locate the area of his interest on the soil map appended with the report. On the map, each soil mapping unit has been delineated are represented by symbolic expression. The abbreviated symbol of mapping unit reflects information about the name of soil series, soil depth, surface texture, land slope and gradient erosion status. The soil mapping unit is demarcated as BP5dB(A)1/C/B where ‘BP’ represents for ‘Bispuria’ Soil Series, ‘5’ for very deep soil depth, ‘d’ for sandy loam surface texture, ‘B(A)’ for very gently sloping (1-3%) bunded with nearly level to level(0-1%), ‘1’ for none to slight water erosion. The details of the soil mapping units, their description and interpretative groupings have been shown in Annexure-I (Guide to Soil Mapping Units). The differentiating morphological characteristics of Soil Series are furnished in Table 6 and the PedonDescription of the soil series are described in Annexure-II.Micro- watershed-wise mapping units along with their area extent, present land use and management status are given in Annexure -III. The symbols used in the report and the analytical methods used for soil analysis are also illustrated in Annexure-IV& V respectively.
