• Industrial foods selectively bred for non-nutritive qualities:
‣high yield‣ large, uniform size‣ pest & disease resistance‣ rapid growth rate
• Heirloom, open-pollinated varieties: higher nutrient levels
• Diversity of cultivars = wider spectrum of phytonutrients

• Soil Composition Commercial Ag relies on N-P-K fertilizers only; organic Ag uses compost to build soil fertility for full spectrum of nutrients
• Facilitated Root Uptake Herbicides/pesticides (& low organic matter soil) kill soil organisms essential for root uptake of nutrients
• Benefits of Pests Plants make phytonutrients to protect from pest pressure (when pesticides applied, lower level of these nutrients develop)

WHY do organic foods have higher nutrient levels?

LOCAL• Nutrient levels drop post-harvest, during shipping
& storage:
‣SPINACH: ↓ 30% folate in 1 wk (if kept in dark); ↓ 100% vit C in 4 days
‣POTATOES: ↓ 50% vitamin C in 2 months, ↓ 80% in 4 months

SOMEPLANNING
Planning for Success
Will It Grow?• Climate (USDA hardiness zone &
microclimate conditions)• Location (6-8 hrs sunlight) • Soil (drainage, pH, compost) • Water (rainfall vs irrigation)
Design Tips• Ornamental considerations (select
plants for beauty, winter interest) • Space (consider mature size of
plant, use dwarf /semi-dwarf varieties)
• Easy access (place high-use items,
like herbs, near kitchen door)• Accessibility (e.g., raised beds &
deck containers)
Effort Required• Time & Care (use perennials, mulch
for weed control)• Pest considerations (disease-
resistant cultivars easier to grow organically)
• Fruit drop (will it stain nearby deck or walkway?)
• Use (plan to put up & store harvest, share, donate to food pantry)
26
SOW WHAT?• Grow what you like to eat (favorites)
• Nutritionally superior varieties (↑ ORAC) not found in markets
• Super foods (goji berries, sea buckthorn)
• Family heirlooms (e.g., your grandpa’s favorite tomato)
• Cultural / ethnic favorites not readily available in markets
