He went to several production, social, and health centers, among others. Fidel praised the application of science and technology in rice harvesting in the westernmost province of the country. This will double yields and save almost half of the amount of water. Touring several Pinar del Rio areas, the chief of the revolution gave special attention to the terraces being built in the rice fields. This method will allow total mechanization of irrigation systems and will make the work of farmers more humane. He explained that some 300 hectares with 1 million cubic meters of soil are being worked on at this time. Some 130 million need to be moved. First, the organic layer is removed, then the clay is leveled; and later, the organic layer is put back. This will result in a gigantic field from Havana and Pinar del Rio. Rice harvesting is rotated with tomatoes and beans. Fidel also visited the provincial capital's multiple-use building that is about to be completed. It has room for 3,000 spectators and 16 sport disciplines can be practiced simultaneously. -END-
