The presentation provides information about composting. Ellen Book, a Master Gardener with UF/IFAS Extension in Miami-Dade County, gives a lecture on composting 101. The chat box will open at the end for questions. Various composting methods are discussed including tumbler bins, sheet composting, and vermicomposting with worms. Active management through turning, aeration, and maintaining the proper carbon to nitrogen ratio can accelerate the composting process.

the soil surface like a garden lasagna
right onto a future growing space.
Trench Composting - composting
directly in the soil
Cold Bin Composting Fill your
compost bin halfway with browns and
bury kitchen scraps
Bokashi Bucket anaerobic bacteria
(grass-like inoculated bran, rice, dried
leaves sprinkled over scraps). 10
days to ferment & “pickle” waste,
forming an acidic organic matter that
must be dug into the soil or added to
a compost pile.
TYPES OF COMPOSTING
101. “The secret world beneath our feet is mind-blowing –
and the key to our planet’s future : Don’t dismiss soil:
its unknowable wonders could ensure the survival of our
species”

125. Vermi-Composting Definitions
• Vermiculture – Work farming process of
culturing worms to decompose organic food
waste, turning it into nutrient rich material
• Casting – Worm waste, digested food
• Omnivores – Animals that eat plants and
animals
• Hermaphrodites – Animals with male and
female sex organs.

• 5Xs the available nitrogen
• 7Xs the available potash
• 50% more calcium
than 6” of good top soil
• Water soluble nutrient immediately available for
plant intake.
