Broccoli Microgreens Can Diversify Food Systems

Abstract

Current malnourishment statistics are high and are exacerbated by contemporary agricultural practices that damage the very environments on which the production of nutritious food depends. As the World’s population grows at an unprecedented rate, food systems must be revised to provide adequate nutrition while minimizing environmental impacts.

One specific nutritional problem that needs attention is mineral (e.g., Fe and Zn) malnutrition, which impacts over two-thirds of the World’s people living in countries of every economic status. Microgreens, the edible cotyledons of many vegetables, herbs, and flowers, is a newly emerging crop that may be a dense source of nutrition and has the potential to be produced in just about any locale.

This study examined the mineral concentration of broccoli microgreens produced using compost-based and hydroponic growing methods that are easily implemented in one’s own home. The nutritional value of the resulting microgreens was quantitatively compared to published nutritional data for the mature vegetable. Nutritional data were also considered in the context of the resource demands (i.e., water, fertilizer, and energy) of producing microgreens in order to gain insights into the potential for local microgreen production to diversify food systems, particularly for urban areas, while minimizing the overall environmental impacts of broccoli farming.

Regardless of how they were grown, microgreens had larger quantities of Mg, Mn, Cu, and Zn than the (mature) vegetable. However, compost-grown (C) microgreens had higher P, K, Mg, Mn, Zn, Fe, Ca, Na, and Cu concentrations than the vegetable. For eight nutritionally important minerals (P, K, Ca, Mg, Mn, Fe, Zn, and Na), the average C microgreen:vegetable nutrient ratio was 1.73.

Extrapolation from experimental data presented here indicates that broccoli microgreens would require 158–236 times less water than it does to grow a nutritionally equivalent amount of mature vegetable in the fields of California’s Central Valley in 93–95% less time and without the need for fertilizer, pesticides, or energy-demanding transport from farm to table. The results of this study suggest that broccoli microgreens have the potential to be a rich source of minerals that can be produced by individuals, even in urban settings, providing better access to adequate nutrition.

Keywords: microgreens, food systems, minerals, urban agriculture, distributed agriculture, sustainability

Ed.: We note that other studies have reported even higher relative concentrations in cotyledon plants compared to their mature equivalents.

Starting in December Tacoma Urban Leage will host a training program on hydroponic gardening. The first seminar will take place December 9 at the League's office. The training is offered in cooperation with Garden of Eden Urban Farming and Maxine Mimms Academy and will be coordinated by Michael Twiggs.

Since spring 2017, Tacoma Urban League has sponsored a hydroponic gardening demonstration garden. A group of students and young entrepreneurs in training is experimenting with growing as part of a future independent commercial project.

Future training sessions will range from DIY home gardening to commercial scale. For more information contact Michael Twiggs via the GOEUF contact form here.

Far too many of our youth are falling through the cracks - not being serviced in our education system. They are simply not engaged - and if you can't engage them - you can't teach them.

For many years, our approach to instruction has always been a piece meal, cumulative learning experience. Students were given a piece of information to be studied and analyzed; then a second piece; and then another to be combined and studied together within a predetermined context. This was the learning experience, and its been tremendously successful - till now.

Those of us on the front lines have noticed a difference in how today's youth learn and respond to instruction. Many do not respond to the cumulative approach to learning. More than a few report that school is boring; unrelated to their life experience. Teachers report that many students are inattentive; easily distracted. They're distracted because they're not engaged.

In fact, the exact opposite approach has proven to be most effective

More Information about the Event

Bronx schoolteacher Stephen Ritz suffered great personal loss. So he refocused on everyone else's kids — and turned a class with a 40% attendance rate to a 93% attendance rate. He was teaching in one of the most troubled schools in the South Bronx. It had a 17% graduation rate, lots of violence, lots of poverty, and lots of really hungry kids.

Many of the people who live in the South Bronx also suffer from something called "food insecurity." Food insecurity means you don't know where your next meal will come from. For people who live in food deserts, this is a fairly common feeling. Most of his kids are homeless. Many are in foster care.

So he and the kids created the Green Bronx Machine

I've noticed recently that there is a lot of incorrect or outdated information regarding wood pallets. My company makes dozens of pallets each day so I thought I would clear the air...

More companies are starting to build one-time-use pallets or use heat treatment rather than Methyl Bromide fumigation. Pallets now require an IPPC logo which certifies that the pallet was heat-treated or fumigated with Methyl Bromide.

We've had mixed success with tomatoes in our Seattle project, but others have had better outcomes. Here's one 2014 story from Southern California..

The first strawberries in our newest growing environment, a vertical tower, have begun to redden. This first crop will be subject, of course, to a bit of "professional sampling and quality control" by the staff, but thereafter we will be moving toward a distribution process. By late fall, when others are hiding from rain and snow, ours will be ready to enjoy for the holidays.

The first lettuce crop at our Seattle facility will be ready for harvest soon. The photo shows project director Michael Twiggs with some plants under cultivation. They will be available as "living lettuce" in April. The plants are doubling in size weekly, and this image is already a week old. Also shown are collards, peppers, tomatoes and other species under experimentation as we determine the best combinations of light and nutrients for our facility. (Sorry for the bad pun.)

Our Tacoma project is under way with the planting of our first lettuce crop. We look forward to harvesting our first green salad makings in January. Follow the project on this page.

Deliveries of equipment for our Central Area Urban Gardening project in Seattle are due to arrive during the week of June 16. Our projected lead time to the first harvest is about six to eight weeks. We will be announcing specific dates as the project proceeds.

Growing your own food is a revolutionary act! It reconnects you with the source of nutrition essential to maintaining your health and well-being.

One of my most important responsibilities as a Deacon is to contact, visit and pray with/for our members that are at home and in hospitals and nursing homes throughout the area. In doing so, I’ve learned of the challenges many face in health care, treatment and the prevalence of chronic illnesses like high blood pressure, cancer, heart disease, diabetes, kidney failure, asthma and other respiratory illnesses that take away our loved ones way too soon.

As I became aware of the disproportionate numbers of people affected in our community and in my own family, my natural response has been to do the research to determine what was being done and the prognosis for remedy or cure. What I found was increasingly more expensive treatment options that in many cases, was worse than the illness being addressed. I learned of the connection between the quality, freshness and nutritional content of the food we eat and what our bodies really need to fight off colds and viruses and other common illnesses.

I wanted to sound the alarm, make some picket signs, get some folk together,
