I have prepared materials on Shemittah in both Hebrew and English. Teachers may be interested in these pages on the underlying reasons for Shemittah and the ethical/spiritual values of Shemittah. To access them, click on the links here - [

Visitors to Israel may want to visit the Botanical Gardens in Jerusalem that has a special area that serves as a Shemittah park. The park has information in English, including information on how to apply the values of Shemittah in modern times.
Behatzlacha!
