The grain crops that we humans depend on daily to hold body and soul together are annual crops — they have to be planted every year. They germinate, bear their delicious product, and then die off; the following year, a brand new crop is put in to take their place…
Perennial grain crops, if they existed, could require less fuel, less fertilizer, less herbicide and pesticide, and help prevent erosion by remaining deeply rooted in the soil throughout the winter (and indeed for years). Perennials return nutrients to the soil, where annuals require artificial fertilizers to supplement depleted soil, and return nothing. According to a paper in the current issue of Science, perennial grains, currently being researched at a number of universities, including Washington State University (WSU), could become the norm within two decades…
According to John Reganold and Jerry Glover of WSU, lead authors of the paper, the perennialization of grain crops would count among the greatest innovations in the history of agriculture, feeding the planet’s hungry humans in a much more efficient, future-proof way.
Whenever I hear of genetic modification of agriculture it freaks me out. I guess I read too many Michael Crichton books as a kid but it just seems like a very, very dangerous endeavor. Especially at this point as we watch how our technological skills have lead us to an unstoppable oil spill just because we could.
