**Urban Farmer, Will Allen Grows One Million Pounds of Food in the Dead of Winter**

The article clarifies that the entire growing season is the entire year, not just the winter.

http://www.realfarmacy.com/urban-fa...illion-pounds-of-food-in-winter-without-heat/On just 3 acres they are producing 1,000,000 pounds of food each

year! How are they doing this?

-10,000 fish

-300-500 yards worm compost

-3 acres of land in green houses

-Growing all year using heat from compost piles

-Using vertical space

The author walks the reader through a quick survey of “bio intensive” farming.

Think of it this way, the standard planted row may have 2 or 3 rows of veggies. Bio intensive will plant 12 rows; thats already 4 times the produce. Now add in onions, for example, that grow vertically above sweet potato vines, this increases production a lot. Now add to that 4 harvest per year vs the standard one season growing season. Now you have 4x more productivity. This brings us to 4×4 or 16 times the productivity of the standard growing methods.

If you add to that hanging pots to add more growing space you have again increased productivity. I personally have not used vertical space in that way. A snap shot of my experience is growing one sweet potato per 1.5′ x 1.5′ area (2.25 square feet.) This one plant produces on average 12 pounds of root per plant and in that space I grow 4 to 6 leeks adding a pond of produce.

Now, the vines grow all over the place, and I tie some up, are not confined to that 2.25 square feet of soil space. From each plant you can easily average 3 pounds ofdelicious edible leavesas you pick them over the growing season. At this point alone I am averaging 16 pounds of eatable food in 2.25 square feet or 16/2.25 about 7 pounds of food per square foot.

Finally, the author engages in some back of the envelope math and comes up with the million pound figure. [my emphasis]

Now that is in ONE GROWING SEASON. As I also grow fava beans, wheat, and fodder greens for two more seasons so my yelid is averaging 8 to 10 pounds in a year.IF I did this on 3 acres of growing space, excluding foot paths and green house walls etc. then my production would be 8 pounds per square foot * 43560 feet acre * 3 = 1,045,440 pounds of food.It is possible to get even more by choosing the right crops and getting 4 harvest per year. I have settled on 4000 square feet of growing space per person for providing pretty much all the food a person needs. I suggest anyone starting out begin with a very small garden and do it well. Something like a 5′ by 20′ growing bed would be the most you would start with.

Neither accompanying video mentions crop yields on Will Allen’s small farm.

I am an amateur gardener with limited knowledge of the topic.

Is any of this even close to possible?
