Alegría Fresh: A Prototype Urban Farm in Irvine, California Uses GardenSoxx

A commercial venture is on the move, and its timing is great, as it proposes to save water, fertilizer, and space, while providing fresh, nutrient-dense produce in urban areas.

This Southern California company is setting up an urban micro-farm -which claims to save large amounts of water- in Irvine, California during this time period when the extreme-drought of California is grabbing so many headlines.

The company is called Alegría Fresh, and they have various products on the market which are intended to grow fresh produce by using hydroponic techniques.

They have devised a mini-vertical garden system for urban dwellers for use in small spaces. Their vertical farm set-ups use coconut fiber (coir) instead of soil.

Their latest venture, Alegría Soxx Farm, uses 7500 linear feet of GardenSoxx on one-fifth of an acre in Irvine, California to grow 15 different vegetables, for a total of 13,000 plants.

They expect a 70 percent reduction in the amount of water needed to grow this produce, and a 50 percent reduction in fertilizer required because of the rich growing medium used. They also expect high yields, greater pest resistance, and faster growth rates, calling this a “paradigm shift in urban ag”.

Furthermore, they suggest that this prototype farm, and other future urban micro-farms like it have a juice bar, salad bar, and small farm stand alongside it to sell produce direct and employ local workers, creating a revenue stream that can support the farms.

All Sounds Great, But a Few Comments . . .
One question that I have, should any of the fine folks from Alegría drop by and read this, is how does this farm save water, when the GardenSoxx Q&A states, “as the mesh breathes, it will dry out sooner than normal soil.” I’d love to see an answer in the comments below, please, as many people are looking for solutions such as this to help grow food in our urban areas.

My other question is how adaptable would this system be to other regions of this nation, besides our prized Mediterranean climate growing region of Southern California?

Finally, I love innovation in food growing, but how I wish it didn’t (so often) involve greater use of plastic.

UPDATE: I’ve noticed the video isn’t working, which really is necessary to understand this set-up. See this page for another video. And here is a video of their vertical hydroponic gardening system.

Bioregional Agriculture in Colorado

“Our food system is broken. What kind of society do we live in that pays all of our farmers to grow the same five crops? —Adam Brock”

Adam Brock, who helped found Denver’s by-now-famous GrowHaus*, tells us that we need a bioregional cuisine here in Colorado not unlike the Cajun food found in the Gulf area. Because we live in a region with very little precipitation, we need to start listening to the land, because we can only get our crops that we do today by working against nature. By growing bioregional food here on the High Plains, we’d use less water and produce food with better nutrition. He suggests eating foods such as a salad made with Sorrel, Bison, and Nopali (Prickly Pear Cactus).

Brock explains that Colorado’s farmers have to play into the commodities markets to compete economically with a result that our state’s top crop is wheat, followed by corn, hay, millet, sorghum, and sunflowers. Showing us a pie chart of the state’s water allocations in 2011 (@3:35), 44 percent of Colorado’s water goes to irrigation for agriculture and 30 percent to power generation.

Here is his list of plants that he recommends we eat and plant in our gardens, because they are native and/or suited to our climate:

• Nopal cactus – prickly pear cactus
• Sunchoke (also known as earth apple or Jerusalem artichoke)
• Sorrel (lower right photo)
• Sea Buckthorn
• Currant
• Burdock
• Amaranth
• Goji berry
• Goumi
• Jujube
• Lovage
• Nanking cherry
• New Zealand Spinach
• Prairie turnip
• Western Sand Cherry
• Yellowhorn

Brock has a website (atriplex.org) which lists more plants he recommends for food that work with nature here in Colorado.

He is also instrumental in helping to plan Denver’s first public food forest.

3 Picks: DIY Verticle Garden, Microgrids, E85 Nonsense


Photo credit: The Dirt

Below, are today’s three chosen agricultural-related news picks.

1) A DIY Verticle Urban Garden Using 2-liter Pop Bottles: Phil Stamper posted instructions on how to make a hanging bottle garden. This is a verticle urban garden system that anybody can do with some rope and empty pop bottles. It comes from the Brazilian design firm, Rosenbaum, and it was such a hit that they released these instructions so that they are available to everyone. (Please go to the source to view the instructions.)

2) ENERGY: Is the Future Micro-Grids? “One of the most under-reported stories in the U.S. energy industry today is Connecticut’s ambitious electricity pilot project—one that could have a widespread ripple effect across the country. On July 24, state government officials announced plans for nine micro-grid projects as part of a Micro-grid Pilot Program aimed at ensuring electricity grid resilience and reliability during severe weather events. “Micro-grids” are essentially small-scale electricity generation and distribution systems that integrate various distributed energy resources and can be managed locally and, if necessary, independently from the main grid. Diesel-powered micro-grids are common in the rural areas of many developing countries such as Haiti, Indonesia, and the Philippines, and some military bases, telecommunications bases, and Internet server farms have done the same, in order to ensure a steady flow of power even if a natural disaster or terrorist attack should take down the main grid. … “

3) How much E85 would be consumed if we gave it away? That is my question for Bruce Babcock (of Colbert Report fame) at Iowa State, who suggests that we need an economic incentive to get past the ethanol blend wall by having E85 available at more stations and by reducing its price in a piece titled, “Price It and They Will Buy: How E85 Can Break the Blend Wall”. (Pretty sure I was not his intended audience.) He says, “The resulting demand curve for ethanol above the E10 blend wall suggests E85 consumption of about one billion gallons if E85 were priced to generate a six percent reduction in fuel costs. If the price were lowered further to generate a 15 percent reduction then about two billion gallons could be consumed, and a 30 percent reduction would be needed to induce three billion gallons of consumption. … rather than being a physical barrier to increased ethanol consumption, the E10 blend wall is an economic barrier that can be overcome by increasing the incentive for drivers to use E85 to fuel their vehicles.” K.M.: Or, maybe it would help if you labeled it what it really is. Hardly anyone is aware of the fact that the ASTM lowered the minimum requirement of ethanol in E85 to 51 percent “E51″ in early 2012… “to ensure that ethanol fuel blends for flex-fuel vehicles can meet seasonal vapor pressure requirements in all regions of the country.” Next up, I’d like to see reports from Babcock on 1) the non-mandated use amounts of E85 in our top five corn producing states, 2) the average ethanol blend produced under the E85 label today, 3) who will be paying for the 30 percent price discount of E85 in his proposal and what will that cost? 4) how do your cost discount incentives for selling E85 compare to energy content in the product? and, 5) How much would your economic incentives contribute to the problems of water quality, habitat and soil loss in your state of Iowa?

(Note that the EPA has recently indicated that it will reduce targets in 2014 to address “blend wall” concerns, and, the anti-ethanol sentiments and voices are heating up in Washington, on TV ads, and elsewhere.)
