LA 390 -URBAN FARM
THE URBAN FARM READER - SUMMARY SPRING 2021
| Question | Answer |
|---|---|
| Brassicas | kale, broccoli, (cabbage, brussels sprouts) |
| Solenoids | tomatoes, potatoes, peppers, eggplant |
| Cucurbitaceae | squash, cucumbers, melons, winter and summer squash |
| Asteraceae | lettuces, sunflowers, daisy |
| Liliacea | onions, garlic, collets |
| Amaranthaceae | Shard, beets, spinach |
| Umbelliferae (carrot family) | carrot leafs, phenyl |
| what is soil? | Air(25%), water(25%), mineral(45%), organic matter (5%) |
| Characteristics of soil, sandy soil (how do they drain, they don't retain water) | Clay(doesn't drain well), due to being stacked |
| Soil Nutrition - NPK | Nitrogen (green leafy growth) Phosphorus (root development and flower development) Potassium (nutrient uptake, protects plants against disease) |
| Trace minerals (2) | Calcium (cell wall structure) Magnesium (growth) |
| Why do you need water drainage? | Good: Helps to protect sensitive roots from rot, fungus and bacteria Bad: (Synthetics) Drains nutrients out of soil (pollution) |
| PH scale | (6.5-7 in soil) Bacteria death, bacteria functions within a certain scale in PH |
| What we did this quarter | Planting, digging begs, cover crops |
| Plant seed | (Depends) twice the size of seed (approx x2 diameter) |
| Synthetic and organic fertilizer, what's different? | Synthetics release minerals quickly (green revolution) PRODUCED IN LABS, as opposed to organic |
| Why not 50/50/50? | Can burn plants Synthetic can cause 'on point' runoff |
| Soil Biology | Nodes on roots (nitrogen fixation) (Bacteria takes atmospheric nitrogen) |
| Plants produce carbohydrates (sugars) Why does plant send portion of sugars to roots? | Feed the growth for bacteria and fungus...fungus wraps and protects roots while feeding off the roots |
| How big is thermophilic compost | (A square yard by a square yard) YARD x YARD x YARD |
| 2 things in compost | (Nitrogen green) green leaves, coffee, manure (Carbon brown) dead leaves, straw, cardboard TO CULTIVATE AND INNOCULATING SOIL W BACTERIA AND FUNGUS , biological cycle to break down organic matter Compost helps breaks down nutrients added to soil* |
| FILM Monoculture -cultivation of a single crop in a given area.(only one plant. Etc corn) monocropping, why? | It's easier to plant one plant and harvest and subsidize and easy to fertilize Disadvantages: plant growth loses nutrients over time, disease, can destroy all the plant, soil becomes dead, loses biodiversity |
| GENETICS plants can cross pollinate, plants hybridize (e.g. throw pumpkin and cucumber seeds in compost) grows as a different plant...the problem is, (why is it unwise to save cross pollinated) | (1) They can be infertile (not grow) (2)Not reliable (don't know what plants you'll get) |
| Dead zone in Mexico | Eutrophication, takes oxygen off from water runoff from the Mississippi |
| What is a GMO? Genetically modified organisms | living organisms whose genetic material has been artificially manipulated in a laboratory through genetic engineering. creates combinations of plant, animal, bacteria, and virus genes that do not occur in nature/crossbreeding methods. |
| What are 2 arguments in favor of plants of GMO? | (1)They can help with disease prevention (2)Grow a lot of food (higher yields) GMOs drop the unwanted traits (e.g. reduce drought) |
| What are 3 arguments against GMO | 1) Can't save seed 2) Associated with unregulated chemicals (possible carcinogens) 3) Genetic diversity killer (Also possible weed immunity) |
| Cover crops E.g. crimson clover - why plant?...nitrogen fixation | Prevent erosion Aerate soil Nutrient depletion (Aesthetic s) bee food, flowers, we eat farma beans |
| 3 weed that spread through roots | -bamboo -clap grass -apple mint -bind weed, morning glory |
| 3 weeds that spread thru seed | -Dandelion -humphrey -borage -amorath |
| Why cover pathways? (E.g. straw, wood chips) | -prevents weed growth -not step on beds (Also aesthetics) |
| What was the green revolution? | Idea that we can essentially industrialize agriculture to kill pests and fungus...to manipulate agriculture (1960s-1970s) Depended on applications of fertilizers, pesticides and irrigation to create conditions to high-yielding |
| Fruit trees, why thin them out? | -(e.g. apple tree) to prevent branches breaking Focus energy on certain plants (get bigger apples, greater yield and content) Disease resistance |
