AIM: SWBAT explain the differences between conventional farming and organic farming techniques Please Do Now: 1) What is a yield (in terms of farming)?2) What are the 4 things we discussed that decrease farmers yields?AgendaDo NowFinish Food Inc.Conventional vs. Organic FarmingExam questions we MUST go over

What would you buy?ConventionalOrganicBananas: $0.89/lbApples: $1.49/lbPeanut Butter: $3.99/32 ozCocco Puffs: $4.99/boxChips: $1.99/ 32 ozAunt Jemima Maple Syrup: $5.99/20 ozIceberg Lettuce: $1.59/headEggs: $2.99/dozenBananas: $3.00/lbApples: $3.49/lbPeanut Butter: $9.99/20 ozOrganic Cereal: $11.99/boxChips: $5.99/32 ozReal Maple Syrup: $13.99/20 ozBaby Spinach: $5.99/bagEggs: $5.99 dozenRememberWe are comparing organic farming and conventional farming as black and white different styles, but real farming can (and does) take place on a continuum between these two extremesNotes for todayI would setup up your notes like this (there will be a slide for each box):Use a whole pageConventionalOrganicPestsWeedsDroughtNutrientsWater Management: ConventionalIrrigate Lots of runoff (wasted water)Sometimes center pivot sprinklersInefficient use of water

Water Management: OrganicIrrigateUse drought tolerant varietiesSometimes drip irrigationMore efficientSlower growth of cropsLots of maintenance

Pest Management: ConventionalUsually synthetic chemical pesticides that kill bugsPesticides end up in water and on foodBad for the person spraying them, the consumer if they eat them, and the environment

Pest Management: OrganicCrop rotationNot monoculturesNaturally derived pesticidesBiological Controls (release predators of the bugs attacking crops)Lots of work, lots of money

Weed Management: ConventionalSpraying of synthetic herbicides to kill weedsRoundup Ready GE cropsHerbicides end up in water, food, and environmentBad for the person spraying them, the consumer if they eat them, and the environment

Weed Management: OrganicWeed by handMassive man hours and cost to do thiscover cropsJust live with the lower yields weeds result in

Nutrient Limitation: ConventionalChemical Fertilizers, made with fossil fuelsTons of nutrients are made this wayReleased all at once on to the fields, the crops only get some of themThe rest run off as pollution

Nutrient Limitation: OrganicOrganic Fertilizers (manure, compost)Crop rotationLots more work, less nutrients for the plantsRelease nutrients to the plant slowly and steadily

What is the most important function of leaves in plants?

What is the most important function of leaves in plants?

To perform photosynthesisExplain how the two halves of photosynthesis, the light dependent reactions and the light independent reactions (AKA the Calvin Cycle), are tied togetherExplain how the two halves of photosynthesis, the light dependent reactions and the light independent reactions (AKA the Calvin Cycle), are tied together

The light dependent reactions produce ATP and NADPH, which powers the Calvin cycle.Venn DiagramSeparate sheet of paper please!Organic Conventional
