Crop Production Sustainable Small Farming & Ranching Crop Management
2
Managing Crops Water Climate Soil Pests Rotations and cover crops Tillage Harvest/Post Harvest Equipment
3
Water MS clipart photo
4
Water Quantity available Average annual rainfall and what times of year Alternative water sources – volume, timing Check regulations – water rights Crop requirements – specific to crop Overall crop moisture needs Drought tolerance – root depth, leaf structure Critical water times – fruit set, root development Consistency important for most
5
Climate First and last frost dates (growing season) Average low temperatures (Hardiness zones) Growing degree days (no. of days accumulated above a certain temperature) Fruit ripening Monitoring insects
6
Working around the Climate Appropriate varieties/cultivars Cultural practices Raised beds Transplants instead of direct seeding Season extension tools Greenhouses Tunnels Cold frames Row covers Plastic mulches
7
Season Extension Tools ToolAdvantagesDisadvantages Heated double poly greenhouse Long season; environmental control High initial costs; high utility costs to maintain Single poly high tunnel, unheated Lower cost; extends season Minimal frost protection Cold framesHardening off transplants Limited volume restricts uses
9
Season Extension Tools (cont.) ToolAdvantagesDisadvantages Solid row coversEnhance early growth Can overheat; require hoops Floating row covers Enhance growth in field; exclude insect pests Must be removed for pollination; May tear in wind Plastic mulchesEnhance early yield; easy to use Annual removal and disposal cost

15
Crop Rotations Numerous ecological and other benefits to the farm Consider plant characteristics to help you develop a plan Plant families Moisture requirements Rooting depths Nitrogen fixing plants Warm season - cool season crops Allelopathic crops Cover crops/green manures
16
Cover Crops and Green manures Keep it covered: Prevent erosion Shade out weeds Prevent freezing and thawing of soils Hosts for beneficial insects Incorporate it: Add nitrogen Increase organic matter
17
Cover Crops and Green manures
18
Use of Cover Crops/Green Manures Identify your problem N source, fight weeds, soil builder, erosion Identify when you could fit them into your rotations late summer, winter, spring ? Identify the right type of cover crop Depending on use, what does well

Use of Cover Crops N Source Soil Builder Erosion fighter Loosen subsoil Weed fighter Pest fighter Winter peas Hairy Vetch Medic Rye Clover Barley Rye Barley Sorghum cross Clover Rye Wheat Barley Rye Sorghum

Soil Cultivation
24
Soil Cultivation Methods Different types: deep tillage, shallow tillage, surface cultivation Equipment varies Used for different purposes
25
Impacts of Excessive Tillage Decrease soil organic matter Reduction in soil biological activity Destruction of soil aggregates Reduction of nutrient & water holding capacity Loss of soil pore space and decreased gas exchange
26
Conservation Tillage Reduced tillage by planting directly into last year’s crop residues. Ridge tillage and no-till are different types Other methods include: mulch tillage kill mulch living mulch zone tillage
27
Minimum Tillage of Vegetables? Check out Steve Groff’s web site: Cedar Meadow Farm Permanent Cover Cropping System http://www.cedarmeadowfarm.com/
28
Harvesting considerations When and how to harvest Labor requirements
29
Handling and Storage Proper equipment and process Sorting/packing Storage
30
Crop production summary Management of sustainable cropping systems relies on planning ahead. Things to consider in your plan include: Planting methods Crop rotation plan Use of cover crops/green manure Tillage strategies Timing of harvest and post-harvest handling procedures
