saurashtra and kucch region

Saurashtra and Kachchh Region consist of Rajkot, Junagadh, Porbandar, Jamnagar, Bhavnagar, Amreli, & Kachchh District.

Accordingly most of Soils in Saurashtra region is having shallow (25-50 cms.) to moderately shallow (50 to 75 cm) depth Soils Whereas Soils of Kachchh region have moderately deep (75-100 cm) to deep (100 to 150 cm) Soils Mostly Northern part of Saurashtra region comprises of shallow depth Soils, whereas Southern part have moderately shallow to moderately deep depth Soils, Gir area has very shallow (10-25 cms) depth Soils. Some part adjoining Rann of Kachchh have very deep (more than 150 cm) Soils.

Soil texture acts as a guide to many Soil characteristics directly or indirectly related to plant growth. Three textural groups used are clayey (fine), Loamy (medium) and Sandy (Coarse). The majority of Soils in Saurashtra region are clayey (fine textured), whereas in Kachchh region, Soils are Loamy (medium textured). Some scattered parts of Saurashtra region have Loamy Soils and Some parts of Kachchh have sandy Soils.

Drainage affects the soil-air-water relationship in Soils and Suggests the availability of Oxygen in mapped soils for root ramification. Majority of the Soils are well drained in Saurashtra and Kachchh region. Some Scattered parts have Some what excessive drainage.

The information on the degree and extent of salt-affected soils and the depth of its occurrence is basic, for ameliorating such degraded soils. The soil salinity / sodicity map provides this kind of information for optimising land use. Major area of Saurashtra and Kachchh region are non-saline.

Costal area of the Saurashtra and Kachchh region are saline. Some parts of Kachchh near Rann, coastal area of Porbandar and Bhavnagar district are strong to very sever saline. North-Western part of Kachchh and costal part of Bhavnagar district are moderately strong saline. Some part of Rajkot district near little Rann of Kachchh, some coastal part of Jamnagar, Junagadh, Porbandar, Amreli and Bhavnagar are slightly saline.

Some interior parts of Amreli and Bhavnagar district, some coastal parts of Rajkot, Jamnagar, Junagadh, Amreli and Bhavnagar district and Western part of Kachchh are having slight sodicity in soils. Bhal area of Bhavnagar district has strong sodicity in soils. The coastal part of Porbandar district has moderate Sodicity in soils.
