This is our Doomsday Soybean Seeds page. It tells how many soybeans one would need on hand in an emergency situation to eat and to plant to reproduce for the next season.
Soybeans originate in Asia, and their fresh shell and dry forms are highly regarded for their yield, protein, and oil content, as well as a multitude of nutritional uses. Typically used at the green shell stage as "edamame," other uses include green and dry cooking, flour, soy milk, tofu, soy sauce, and miso. Dry soybeans average 40% protein and 18% oil.
As you can see, soybeans can be used for a lot of different things if you have the right processing equipment. They can also be used as animal feed.
We are just focusing on using them as a dry seed for eating and storage.
Also soybeans are great nitrogen fixers.
For human consumption, soybeans must be cooked with "wet" heat to destroy the trypsin inhibitors. Raw soybeans, including the immature green form, are toxic to all mono-gastric animals.
Unfortunately, many of the soybean products you buy in the store have been made using soybeans that have been genetically modified. You will want to read the labels very carefully to make sure you are getting non-GMO products.
We sell only non-GMO Seeds.
One cup of dry soybeans has about 800 calories. They have lots of other good stuff as well.
It would take about 50 soybeans per cup. One plant produces about 55 soybeans. So one plant per cup. One cup is about 300 calories. Based on a 1200 calorie diet, one would need 4 cups of soybeans per day or 1500 plants per year.
You would need three 32 square foot raised beds to grow your soybeans for one person per year. Included in this would be 30 plants to produce seeds for next year and 30 plants as a back up.
1800 plants a years should be enough to cover for any loss, seed production and human consumption.
You can let the pods dry on the plant, then harvest and thresh them. Dried soybean seeds can last to 2 to 3 years if kept dry.
Stagger your plantings so that you are not harvesting all the soybeans at once.
All of the variety information on the David's Garden Seeds® website, including the days to
maturity, color and size are based on data from tests done at specific
locations. Many factors, including geographic location, daytime and
nighttime temperatures, the availability of plant nutrients, many unknown climate factors and insects/pest interact to determine a variety's
performance. For information on which varieties will perform best in
your area, we recommend that you contact your local county extension agent or a Master Gardener.
