Grow four million calories - PEM BB gardening.iron.fourmillion

This is a badge bit (BB) that is part of the PEM curriculum.  Completing this BB is part of getting the iron badge in Gardening.

Let's see if you can grow food for a whole family in one year.  That would be approximately 4 million calories.  





To put it in perspective, there are 10,000 calories is in:  
         o 35 pounds of potatoes
         o 26 pounds of sweet potatoes
         o 42 pounds of apples
         o 53 pounds of unsweetened applesauce
         o 10 pounds of prunes
         o 6 pounds of dried strawberries
         o 55 pounds of onions
         o 50 pounds of winter squash
         o 30 pounds of sunchokes
         o 7 pounds of field corn or rye or most grains
         o 7 pounds of dried black beans
         o 4 pounds of sunflower seeds
         o 3.5 pounds of hazelnuts

To complete this BB, the minimum requirements are:
  - Grow, harvest and use 20 or more species totaling 4,000,000 calories
       -  In cases where members of a species are very different from each other they each can each count towards the 20
               - For example, cauliflower, broccoli and cabbage all count despite being brassicas
               - Zucchini, acorn squash and spaghetti squash all count despite being cucurbita pepo
  - Each species needs to contribute at least 10,000 calories and no more than 1,000,000 calories
  - "Use" means for human sustenance (drying, canning, root cellaring, freezing, fermenting, eating, selling, giving, etc)  
  - "Use" does not include things like animal feed or cover crops
  - Foraging is not allowed for this BB
  - Perennials, biennials and annuals are fine
  - Annuals and biennials need to be grown by you from seed you saved
        - Garlic cloves, seed potatoes and sweet potato slips come from your garden
  - Established perennial plants can be used for this BB
  - No more than 25 contiguous square feet of a given crop in one spot
        - Polyculture is encouraged
  - These can be plants/seeds you planted in earlier badges
  - All food needs to be harvested in the same calendar year
  - No hydroponics or aquaponics

Provide proof of the following as pictures or video (<2 min):
  - Several views of garden early in the year with young plants
  - Several views of garden in mid summer from the same vantage points
  - View of food forest, orchard or other perennial systems in mid summer
  - For one-time harvests (potatoes, squash, apples, etc) show the harvest in the field
  - For repeated harvests (tomatoes, lettuce, beans, etc) show a harvest in the field
  - Detail the weight of each species and how many calories it represented
