Soil & Crop Combination

I am trying to get hold of Soil & Crop combination.  If anybody has info, please point me to the right place.

thank you Sir,

Your question/Requirement are not clear sir.

I felt a need to create a database wherein we can identify the Crops that grow in certain Soils.  By this way, the farmers can easily identify the crops that grow in their soil and it can be used for decision making.

Hope this is clear now.
