- المحاصيل المعمرة هي محاصيل - على عكس المحاصيل السنوية - لا تحتاج إلى إعادة زراعتها كل عام. بعد الحصاد، تنمو تلقائيًا مرة أخرى. من خلال القضاء على إعادة الزرع، يمكن للمحاصيل المعمرة أن تقلل من خسائر التربة السطحية بسبب التآكل، وتزيد من عزل الكربون البيولوجي بسبب تقليل الحراثة المزعجة للتربة، وتقلل إلى حد كبير من تلوث مجاري المياه من خلال الجريان السطحي الزراعي بسبب إدخال النيتروجين أقل.

- Perennial crops are crops that – unlike annual crops – don't need to be replanted each year. After harvest, they automatically grow back. Many fruit and nut crops are naturally perennial, however there is also a growing movement to create perennial alternatives to annual crops. From the 1920s to the 1950s, researchers in the former Soviet Union attempted to perennialize annual wheats by crossing them with perennial relatives such as intermediate wheatgrass. Interest waned when the crosses repeatedly resulted in sterile offspring, and seed yield decreased significantly. The next major time the project of perennializing grain was picked up was a wheat hybrid developed by the Montana Agricultural Experiment Station in 1986, which the Rodale Institute field tested. For example, The Land Institute has bred a perennial wheat crop known as Kernza. By eliminating or greatly reducing the need for tillage, perennial cropping can reduce topsoil losses due to erosion, increase biological carbon sequestration, and greatly reduce waterway pollution through agricultural runoff due to less nitrogen input.
