Will perenial grains ever be a realistic alternative?

摘要

Perennial grain crops - those you plant only once before harvesting multiple times - would potentially deliver many favourable on-farm attributes, not least savings in seed and fuel costs, reduced cultivations and lower input requirements.Research hasalso shown increased carbon sequestration, improved soil structure, reduced soil erosion risk and better nutrient use efficiency. In addition, they will adhere to many of the key regenerative agriculture principles, including no soil disturbance, a permanent living root in the soil and 100% ground cover. Some perennial crops could be grazed as well as producing grain.
