Geographical information system for delineating soil related constraints in sugarcane growing areas

  • 77 Accesses

Abstract

Thematic maps were generated out of the soil resource inventory study carried out during summer 1999 in sugarcane growing areas of Uttiramerur taluk, Kancheepuram district to generate information on spatial distribution of different soil qualities like soil compaction, drainage, soil reaction, soil depth, soil texture, status of macronutrients and deficiencies of micronutrients. From the thematic maps, the spatial distribution of soil related constraints was prepared. Limitations due to soil depth (2468 ha; 10.36 %), poor drainage (4568ha; 19.18 %), sandy texture (4113 ha; 17.28 %), alkaline soil reaction (6000 ha; 25.20 %), low available nitrogen (23808 ha; 100.00 %), low available P (10149 ha; 42.626 %), low available K (10552 ha; 44.32 %), deficiency of Zn (23333 ha; 98.06 %), deficiency of Mn (2942 ha; 12.36 %), deficiency of Fe (1061 ha; 4.45 %), deficiency of Cu (9676 ha; 40.64 %), deficiency of B (1061ha; 4.44 %) were recognized as the dominant soil constraints for sugarcane production in the study area. Suitable management measures were also suggested to improve the cane yield.
