Why are the leaves turning yellow on the bottom of the tomatoes?

When lower leaves turn yellow it is usually a sign of temporary droughty soil conditions or of a lack of nitrogen. If nematodes are infesting the root system the plants may also exhibit such symptoms. Nematodes are primarily a problem in sandy soils. They are best managed by planting resistant varieties of tomatoes (those with an "N" after the variety name, such as Celebrity VFN).
