Soil & Land Capability Unit

In 1997, the Government of Trinidad and Tobago establish a National Soil Testing and Advisory Service for farmers. Following the closure of Caroni (1975) Limited, the Government of Trinidad and Tobago have initiated plans to allocate to 7,000 former Caroni workers two (2) acres parcels of land for farming. The Soil and Land Capability Unit have been mandated by the Ministry to sample and analyze these parcels of land. The Unit’s protocol is to do two (2) samples per acre, at two depths 0-15cm and 15-30cm.

Soil testing is done throughout Trinidad and Tobago by a dedicated team of officers and assistants. The service also provides Soil Surveys, Cartography and Land Capability Reports.

Land Capability Reports are done for (a) Town and Country Planning (b) Agricultural Development Bank and (c) Private Farmers. On average of fifty (50), Land Capability Reports are prepared per year for an approximate acreage of 100,000 acres.


The beneficiaries are mainly the farming community but also Town & Country Planning Division can make informed decisions re change of land use in areas.
