Garden with Your Pee DIY Projects

| No Comments | No TrackBacks
Humans pee! Yep, and a lot. And wastewater treatment has become BIG systems. But the story isn't a simple one. Sewer treatment is necessary because our urine collects all the waste chemicals from our medications and foods and drinks...and it goes back into our water system. Those New Yorkers are innovative! They are developing an open source innovation project to develop ideas on how to turn pee into hydroponic farming fertilizer.

Urban farming, vertical farms...apartment gardening, these are all new techniques for urban food production in small urban spaces.

Urban food production is a necessary part of food security and reducing the 2,000 miles our typical meal travels to our mouths!

A recent study at Oregon State University has shown that native bumble bee species have consistently high pollination and seed production levels in red clover.

The bumble bee pollination findings offer promise for the use of bumble bee crop pollinators as an alternative to European honey bees, whose populations have recently declined in many areas of the United States.

Red clover, which is grown for forage and as a rotation crop to improve soil, is raised for seed in western Oregon's Willamette Valley. It will not produce seed without pollination, so growers typically place two to five European honey bee hives on each hectare. 

Search for Alternative Pollinators

Bee diseases, mites, and colony collapse disorder have recently limited availability and resulted in higher costs for hive rentals. Given these changes, an alternative pollinator for red clover seed crops is needed.

Worldwide there are over 200 species of bumble bees; some of whom are known to pollinate red clover. While commercially reared bumble bee species are available to growers elsewhere, they are considered exotic species in Oregon and cannot be introduced into the state. This leaves Oregon growers dependent on naturally occurring populations of bumble bees as pollinators. However, there is currently no information on the pollination efficiency of native bumble bee species.

Scientific Evaluation of Blooms and Seed Set

Through funding from the Clover Commission, scientists at Oregon State University investigated native bumble bees in commercial fields of red clover seed crops in the Polk County region of the Willamette Valley. Prior to bloom, researchers covered plants with mesh-screened cages. European honey bee hives were placed in some cages and nests of B. vosnesenskii, a native Oregon bumble bee,in others. Some cages were also left vacant. After bloom, seed yield and seed set were compared amongst the different cages. Seed set was also evaluated in four different fields without cages to assess the efficiency of existing bee pollinators. In addition to analyzing seed set, researchers assessed the diversity and abundance of native bumble bees through visual observations of foragers on red clover flowers and through trapping bumble bees in blue vane traps. 

Pollination Differences between Bumble Bees and Honey Bees

While there were no differences in seed yield or average seed set in cages with bumble bees compared to honey bees, the study revealed:

  • Variability across cages was lower with bumble bees indicating that bumble bee pollination is more uniform than pollination by European honey bees.
  • The abundance of bumble bee peaked during mid-to-late bloom.
  • They recorded six species of bumble bees gathering pollen from red clover flowers. Of these, more than 92% consisted of B. vosnesenskii, indicating that it is the key pollinator in Oregon.
  • 25 more species of native solitary bees, belonging to 12 genera and five families, were collected in the bee traps.


Research Findings

The study has not only documented a great diversity of native bees in synchrony with red clover bloom, but it has also found that seed set was uniform and high across four fields. Under current pollinator regimes, researchers believe red clover seed production is close to its maximum in Oregon.

Solutions for Pollination

"To sustain these high yields in Oregon, we must

  • Conserve the habitat of bees,
  • Use pesticides judiciously and
  • Provide floral resources prior to red clover bloom

Oregon State University entomologist Sujaya Rao, one of the researchers on the study, concluded,  "Globally, where red clover seed is produced, similar studies are needed. If seed set is found to be well below the maximum, appropriate alternative options such as augmentation with commercial bumble bees could be considered."

Research is ongoing at Oregon State University to determine whether high yields can be achieved by native pollinators alone. If so, European honey bee hive rentals would not be required, and this could lead to more economic red clover seed production in Oregon.

I've followed the honey bee crisis known as "colony collapse disorder" because of their close connection with our food supply, with nature, and because bees are one of the few "domesticated" insects in our economy.

Science is finally making headway on what is causing the die off of complete hives of bees.

Penn State researchers worked with the National Science Laboratory of the U.S. Department of Agricultural Marketing Service that already tests commodities such as milk and fruits and vegetables.

Honey has not regularly been analyzed, and bee pollen was not a commodity and so was not analyzed at all. The researchers decided to use types of screening the lab uses for milk and apples, which looks at over 170 pesticides. What they found is quite astounding to me... because of what it says about our agricultural practices.

All of the bees tested showed at least 1 pesticide and pollen averaged 6 pesticides with as many as 31 in a sample.

Honeycomb may contain pesticides applied years ago.

Scientists do not know that these chemicals have anything to do with colony collapse disorder, but scientists have concluded that these pesticides are definitely stressors. Penn State's Dr. Maryann Frazier say, "Pesticides alone have not shown they are the cause of CCD. We believe that it is a combination of a variety of factors, possibly including mites, viruses and pesticides."

While beekeepers will have a difficult time controlling pesticide exposure outside the hive, the Penn State researchers tested a method using gamma radiation for reducing the chemical load in beeswax and they found that irradiation broke down about 50% of the acaricides, pesticides that kill mites.

Sustainable farming is taking "organics" a step further.  The health of an ecosystem is about more than organic production methods... it also depends on habitat for native wildlife, water management ... and more.

Buy food from a sustainable farmer!
Chemical-free fruits, vegetables, and grains, antibiotic and hormone free meats,
free-range chickens and eggs, milk and cheese from grass-fed cows, and more.
chemical free fruits, vegetables, and grains; antibiotic and hormone free meats, free-range chickens and eggs, milk and cheese from grass-fed cows, and more.


A growing number of farmers are choosing to work with nature, and are adopting farming practices that build up the soil, reduce runoff, create habitat for wildlife, treat livestock humanely and best of all, produce safe, wholesome food. But the most environmentally sound farming practices in the world mean little if they don't provide a good income for the farmer. 


Farmers using sustainable methods cannot prosper without the help of urban and rural consumers.

As sustainable and organic farmers explore creative new ways to market their carefully grown products, consumers can support their choice to farm sustainably by purchasing those products listed in the Stewardship Food Directory.

To assist you in preparing meals using locally grown, sustainably-raised products, see our collection of recipes. We also encourage you to hold your own local foods dinner (or potluck, cook-out, banquet, or brunch) to promote the connection between good food and good farming. We have compiled a Local Food Dinner Planning Guide with a few suggestions and resources to get you started. 

The Land Stewardship Project (LSP) is a private, nonprofit organization founded in 1982 to foster an ethic of stewardship for farmland, to promote sustainable agriculture and to develop sustainable communities.

Commemorative 25th Anniversary Poster

For its 25th anniversary, LSP commissioned a commemorative poster by artist Ricardo Levins Morales of the Northland Poster Collective. For almost three decades, the Northland Poster Collective (http://www.northlandposter.com) has featured the art of social justice, the tools of grassroots organizing and activism, and the craft of union workers. For LSP, the artist has created a beautiful piece entitled, "KEEPING THE LAND AND PEOPLE TOGETHER." It is a colorful poster portraying a food and farming system that benefits the land, its people and our communities.

Since its founding in 1982, the Land Stewardship Project (LSP) has worked steadfastly for environmental and social justice in rural America. They began by educating rural and urban people on the ethics of farmland stewardship through cultural programs and by creating a farmer-to-farmer network to help farmers move to more sustainable farming methods. In response to growing concentration of farmland ownership, they demanded that corporations owning farmland be held accountable to good land stewardship practices. In response to urban sprawl, they initiated discussions on smart growth and farmland preservation options.

LSP has helped dozens of communities organize to stop factory farms and linked sustainable livestock producers to potential urban customers. Working in the Sustainable Agriculture Coalition, LSP backed federal policy promoting farming alternatives that are good for the land and good for farmers. We have introduced hundreds to Whole Farm Planning and Monitoring. And they have helped Community Supported Agriculture farms get established throughout the region.

The American Farmland Trust is about more than farms. These folks are concerned about the food supply for everyone -- from rural areas to big cities.

An elaborate food distribution system has beveloped between producers and consumer that has matured into delivering inexpensive, standardized food products. But times are changing because of organic food trends, and scares about contaminated foods from afar. The US food system is evolving in the direction of delivering the "story behind the food" in response to growing consumer demand. But it has a long way to go.

Food that is identifiable as "local," including food that is organically or "sustainably" produced, is a very small fraction of both total regional agricultural production (0.5 percent) and of total U.S. retail sales (2.8 percent). This sustainable sector of the food system is growing rapidly.

Despite the challenges of locating locally grown foods for families and local restaurants and institutions such as schools, there are significant opportunities to increase "eating locally" in San Francisco and the Bay Area. The local food movement in the region has as much momentum as anywhere in the country. Strong Farmers Coops, Farmers Markets, and Community Supported Agriculture (CSA) operations make it almost convenient!

Many public and private institutions (such as schools and hospitals) are now seeking to source food locally. As the fossil fuel era wanes, fresh, local food may gain an advantage in the marketplace over food that is processed and shipped long distances.

Read more about the growing local food trend in the San Francisco Foodshed Report.

California is the leading producer of fresh peaches, plums and nectarines in the United States producing 60% of the peaches, 95% of the plums and 90% of the nectarines.

Most of these fruits are grown within a 50-mile radius of Reedley, a quiet California Central Valley town near Fresno. Other growing areas exist near Bakersfield, Modesto and Sacramento. Approximately 1,500 farmers, small and large, grow these three fruits commercially, hand picking them in the orchards and hauling them to packing sheds.

Guy Fieri Promotes California Grown Products

 

Guy Fieri is known for creating food that is as fun, fearless, and fundamental as his larger-than-life personality. Check out a video from his recent visit to Sacramento where he talked with local California growers…



Boulder, Colo. - (June 13, 2007) - Much more than the fate of the multi-billion-dollar fresh leafy greens industry is at stake in the wake of the 2006 fall's E. coli 0157:H7 outbreak linked to pre-packaged spinach products.

Why? Because increasing daily consumption of fresh fruits and vegetables is an essential first step in improving the health of the average American. Any factor that erodes confidence in the safety of fresh produce undermines ongoing efforts to increase consumption of these healthful foods.

According to a Critical Issues Report released in June 2007 by The Organic Center, the good news is that since last fall, growers and processors of fresh leafy greens, especially in California, have adopted significant, new prevention-based food safety practices aimed at preventing another outbreak.

The study, Unfinished Business: Preventing E. coli 0157 Outbreaks Caused by Leafy Greens, is authored by The Organic Center's chief scientist Charles Benbrook, Ph.D. While noting progress made, the report highlights several additional steps that are justified in light of current science and the magnitude of the issue.

The Western Growers Association led the effort leading to adoption by processors and handlers of a set of "Good Agricultural Practice (GAP) Metrics." Market leader Fresh Express has committed $2 million for research on how to prevent future outbreaks, and Natural Selection Foods has implemented a new "test and hold" program that has helped ensure that all shipped product is pathogen free.

"Prevention of foodborne illness outbreaks requires innovation, attention to detail and diligence from 'farm to fork,'" says Dr. Benbrook.

The new report provides an in-depth discussion of the likely causes of the 2006 outbreak, and includes a dramatic series of pictures of the outbreak field and surrounding area. "One lesson learned is that cattle, manure and fresh leafy greens make for a volatile mix," according to Benbrook. Until more is known about how pathogenic E. coli finds its way to leafy green fields, the report calls for one-half mile separation between grazing cattle and leafy green fields. The GAP Metrics currently require only 30 feet.
