Kehilat Nitzan follows a triennial cycle for Torah reading, where only about a third of the Torah portion is read each year. This tradition has its origins in Palestine, whereas the complete annual reading of the Torah follows an ancient Babylonian practice. The Rabbinical Assembly's Committee on Jewish Law and Standards approved the triennial cycle for Conservative congregations in 1988.
Unfortunately, our chumashim (books in which we follow the Torah reading) show the divisions of the reading in the various sections for each aliyah (call up) to the Torah in the annual cycle rather than the triennial cycle. Triennial listings are available online and in the RA's teshuvah (PDF).
An essay by Rabbi Lionel Moses about the history of Torah reading can be found in the Etz Hayim Torah & Commentary (page 1479).
