Let’s Talk Farming Systems4
Agriculture
CONVENTIONAL
Uses modern
technology
and mechanization.
Stems from
green revolution.
BIOTECHNOLOGY
Uses plant breeding
techniques to develop

organisms.
“RoundUp/Bt/Stacked.”
ORGANIC
Ecological production
System minimizing

Challenges13,14
• Global population growth: 8.3-10.9 billion by 2050.
• Most growth in developing countries.• Increased demand for food, water, energy,
employment.• Wasted food.• Global income growth: With affluence comes
increasing demand for meat.• Cropland loss.• Soil erosion.• Fertilizer costs.• Market speculation.• Aquifer depletion.• Water pollution.• And other climate change challenges…

Key Soil Health Practices12
• No-till: Growing crops without tilling (e.g., plowing) the soil.
• Reduced-till/mulch-till: Tilling the soil in ways that minimize disturbance to the soil or maintain more residue cover than conventional tillage.
• Mulching: Adding plant residue (or other materials) to the surface of the soil.
• Cover cropping: Growing a crop, often over the winter, that will be left in place as residue or incorporated into the soil to increase organic matter.
• Conservation crop rotation: Choosing crop rotations to maximize crop diversity, build organic matter, and improve soil biodiversity.
• Nutrient management: Adjusting the type, location, rate, and timing of fertilizer or other nutrients to meet plant needs and minimize environmental impacts.
• Prescribed/rotational grazing: Managing where and when livestock graze in two or more pastures in order to prevent overgrazing and to optimize pasture growth.

Innovations in agriculture technology help to use fewer resources, including fertilizer, pesticides, water, etc.
Examples:• Technology to maximize
crop space• Satellite imagery to survey
soil• Technology to increase
drought tolerance• Precision agriculture tools
to reduce inputs and improve efficiency

Farm Production Facts
Farmers may choose from four types of production methods:1. Conventional2. Organic3. Biotech4. Indoor, vertical (requires no sun and no soil)
A farmer or rancher may choose to use multiple production methods based on factors including soil type(s), climate, availability of seed or machinery, access to irrigation, growing region, crop prices, and market access and demand.
