Programmes

Soil survey is the process of systematic examination, description, classification and mapping of soils in an area so that predictions can be made about their use and their response to various management practices. Soil survey provides reliable data on nature, extent and distribution of the soil resources of an area for
1. selecting suitable and responsive areas for various agricultural development programmes
2. delineating critical and problem areas requiring immediate treatment measures
3. Suggesting the potential of soil resources and its alternative use
4. Assessing the irrigation suitability of soils and
5. Classifying the land according to its capability for effective management

Soil survey unit was started under the Sate department of agriculture in 1962 with two field units at Thiruvananthapuram and Calicut and a Soil Analytical Laboratory at Konni. In 1967, three additional field units were created to take up pre-irrigation soil survey of the command areas of irrigation projects and problem areas. More units were created in the subsequent years and by the end of the 7th five year plan, 12 soil survey field units were in operation for conducting Reconnaissance Soil Survey, detailed soil survey, pre-irrigation soil survey, command area survey, farm survey, catchment survey and watershed survey. During 1991-92, the soil survey programmes were restructured with the aim of providing the services of soil survey field unit in all the districts. Now all the districts of Kerala are having a field unit each headed by an Assistant Director (Soil Survey) with supporting staff to carry out the various soil survey programmes.
A Central Soil Analytical Lab at Thiruvananthapuram and Regional Soil Analytical lab at Thiruvampady provides the analytical support to the field units. All the publication of the soil survey are undertaken at the Directorate.

NATURE OF WORK
A few user agencies of soil survey are listed below:
1. Soil survey of farms and research stations - Kerala Agricultural University
2. Soil survey of identified watersheds under NWDPRA - Soil Conservation Organization
3. Soil survey of identified watersheds under WGDP - Western Ghat Cell, Planning and Economic affairs Department
4. Aluva Municipality
5. Kerala Rural Water Supply & Sanitation Agency - World Bank aided project of Govt. of Kerala
6. Soil survey of district farms - Department of Agriculture, Govt. of Kerala
7. Malabar Botanical Gardens - Autonomous body of Govt. of Kerala
8. CPCRI Research Station, Peruvannamuzhy
9. CMFRI, Vizhinjam

Types of survey undertaken
Reconnaissance soil survey


The type of survey undertaken when only a broad inventory of soil resources of the area is required. eg. for regional planning- soils mapped at soil association level using small scale map (1: 50,000 or more). An area of 30.62 lakh ha have been covered under Reconnaissance Soil Survey in the Sate.

Detailed soil survey

         Detailed soil survey is the type of survey when high intensity studies are required for preparing actual project plan for proper land use by mapping soil at phase level using cadastral maps in the scale of 1:8000 or larger scales. Detailed soil survey has been completed in 17.57 lakh ha of Kerala.
Under this, soil survey of the command areas of Kuttiyadi, Pamba, Kanjirampuzha, Pazhassi, Kallada, Periyar valley, Chitturpuzha, Malampuzha, Chimoni Mupli, Aralam and Idamalayar have been completed and reports furnished to the Government (26 reports of irrigation projects). The soil survey of all farms under the Government and Agricultural University have been surveyed and reports and various thematic maps furnished for deciding suitable cropping pattern and research programmes. 38 reports have been published so far.

Panchayat soil survey
With the restructuring of soil survey activities at district level, emphasis has been given to panchayat soil survey. High intensity survey is undertaken to record the type, extent and distribution of the soils their potentialities and limitations and problems encountered in each soil. Based on these observations, suitable management requirement for optimum production of each crop in different soils occurring in the panchayat, general development requirements of the panchayat and suggestions for improvement are included in the report along with the various interpretative maps such as soil and land capability map, soil conservation priority map, present land use map, suggested land use map and fertility map. 74 panchayat reports have been published under this programme till now.

Survey of watersheds
Delineation and soil survey of watersheds is another important work undertaken by the soil survey unit. The soil survey unit is entrusted with the task of delineating as well as soil survey of watersheds under national Watershed development Programme and Western Ghat Development Programme. The soil and land resource of the watershed are assessed, the problems that confront the area are identified, suitable remedial measures and management as well as location specific development programmes are suggested. 118 reports under the Western Ghat Development Program and 161 reports under NWDPRA have been published so far.

Special studies
Soil survey unit has been undertaking specialized soil survey programs as per request of user agencies. At present, the soil survey unit is undertaking survey works for Kerala Water Supply Sanitation in Malappuram district and Malabar Botanical Garden, Kozhikode.
