This short piyut touches on these four themes related to Shmitah: release of debts, the rights of the land, the rights of wild animals (who share our food during Shmitah), and the freeing of slaves. The piyut would fit as part of Seliḥot before Rosh haShanah and during Yom Kippur. . . .

Two suggestions for ḥazanim (cantors) and shliḥei tzibur on the High Holidays. . . .

Many people eat special foods as part of a mini-seder at the beginning of the Rosh Hashanah meal and invoke blessings for the year as they eat them. This year, you can add figs to your Rosh Hashanah seder (apples and honey, or apples, dates, beets, etc.) and recite with this kavvanah (intention). . . .

This Haraḥaman (prayer to the merciful or compassionate One) for the Shmitah or sabbatical year can be added to Birkat Hamazon (blessing after meals) during the whole Shmitah year, in order to remember and open our hearts to the sanctity of the land. Say it right before the Haraḥaman for Shabbat, since Shmitah is the grand shabbat, and right after the paragraph beginning with Bamarom (a/k/a, Mimarom). . . .
