So many of our horticulture students at Oregon State University are enthralled with the thought of becoming organic farmers despite the fact there seems to be an overabundance in the Willamette Valley already.
I encourage them to look at the new urban environment, you know the one that covers only 2 to 3 percent of the earth’s surface but consumes nearly 70 percent of its resources. This particular model also predicts that the urban environment is poised to house and accommodate the needs of seven out of every 10 inhabitants by 2050. I recently examined a rooftop gardening operation on the east coast and was simply amazed at what they are doing.
I was thumbing my way through the 355 page Whole Seed catalog from Baker Creek Heirloom Seeds when an article entitled the Brooklyn Grange Farm caught my attention. It is the largest rooftop farming operation in America. They have two sites, one at the old Brooklyn navy yard and one in Queens, NY. Together there is a combined area of 108,000 square feet. This is nearly 2½ acres from which they produce nearly 20,000 pounds of produce per acre.
