Michael Pollan Lectures on Food and Agriculture
Read his book In Defense of Food
Agricultural update. NPK fertilizers are those whose content is Nitrogen, Phosphorous and Potassium.
Fertilizers typically provide, in varying proportions, the three major plant nutrients: nitrogen, phosphorus,
potassium (known shorthand as N-P-K); the secondary plant nutrients (calcium, sulfur, magnesium) and
sometimes trace elements (or micronutrients) with a role in plant or animal nutrition: boron, chlorine,
manganese, iron, zinc, copper, molybdenum and (in some countries) selenium. Sulfur is required for
growing onions, for example. Nitrogen is artificially made by combining Ammonia and Nitric Acid to make
Ammonium Nitrate. Its formula is NH4NO3. Note the double dose of nitrogen.

He mentions urban agriculture and singles out Detroit at one point.
CSA means Community Supported Agriculture
Part of the logic is growing food locally so that you don’t use fuel shipping it.

Hydroponics is being emphasized by a professor in NYC. It is further out but will also combine animals
and crops. One fellow has a system using fish to generate fertilizer for crops, thus creating a closed
loop system.
Most of the current movement is organic, local, rotating crops, etc.
By having animals on farms, one can recycle animal waste in a nature-intended way, thus maintaining
soil quality.
“Urban Agriculturalists”; “Subscriptions to Milwaukee’s first roof-top CSA”, hunting is “solar powered
meat” simply because there is no fertilizer, planting, energy to plant, natural gas to make ammonium
nitrate fertilizer, etc.
The danger of NH4NO3 (Ammonium Nitrate (AN)) is both intentional (it was used to blow up Oklahoma
City) and hazardous with some types of N-P-K Fertilizers, and is responsible for the loss of several cargo
ships.
