Soil: Home to All Plant Roots! PDF

Matching the plant to the soil and creating a hospitable home is the first essential step in successful urban agriculture!

Soil Components
Success Tip:  Compost enhances each of the soil components, making for a living, hospitable environment for urban agriculture crops!

 

• Organic Matter
- Comprised of decayed plants and animals
- Living area with millions of microscopic critters keeping the soil alive and vital
- Texas heat burns up organic matter in our soils
• Water and Air
- Carbon dioxide in the soil combines with water to form a food solution used by plants
- Air provides space for water and root movement
• Plant Nutrients (food)
- Proper balance of 20 elements needed for growth
- Soil fertility is the ability of soil to hold and release nutrients in adequate amounts and suitable proportions
- Proper quantities of water and air are needed
• Factors Affecting the Amount of Organic Matter in Soil
- Long term management
- Type of plants previously grown in area
- Temperature
- Drainage

Soil Depth
Success Tip: The deeper the original matter layer, the less water required for successful landscaping.

 

• Effective Soil Depth
- Depth to which a plant’s root can grow before hitting something that stops them.
- Plants have different depth needs depending on type and size.
- Deeper topsoil holds more water requiring less frequent irrigation.

  Very shallow: 10” or less                    
Shallow: 10” – 20”                              
Moderately deep:  20” – 36”
Deep:  36”- 60”
Very Deep: 60” plus

Soil Horizons
- Soil not only changes across the surface, it changes below the surface as well.
- What we call topsoil is only the beginning.

  - 01 – Organic matter (topsoil, full of living organisms making soil fertile)
- A – Mineral surface soil that has accumulated decomposed organic matter. Usually darker in color than lower layers; does not support plant life well
- B – Mineral subsoil collecting clay and organic matter from above; fine texture
- C – Mineral horizon of weathered parent material; older
- R – Underlying consolidated bedrock – very deep

Soil Testing
Success Tip: Match the plant to the soil or amend the soil to match the plant.

 

• How often?
- Test soil every 3-4 years or when establishing a new landscape.
• How do you test soil?
- Obtain a soil testing kit from your local nursery or Texas AgriLife Extension office.
- Use clean equipment, do not use brass, bronze or galvanized tools.
• Where do you obtain soil samples?
- Each sample should represent only one soil type or area for example:  a lawn, vegetable garden or perennial landscaped area
- Take at least 6-8 sub samples and combine to make one sample.
- If one area of the yard seems healthy and another has bare or yellow areas, sample these areas separately.
• How deep do you sample?
- Lawn: 4” excluding any turf thatch
- Vegetable and flower gardens:  4” - 6”
- Shrubbery: 4” – 6” at base of plant

 

Successful Urban Agriculture matches the right plant with the right place
PDF

Success Tip: Having trouble knowing what to do and how to do it? Consult your local nurseryman/landscaping professional for knowledgeable insights to match the right plant with the right place.

Your Urban Farm
- Front yard (public space)
- Back yard (private space)
- Side yards (transition areas)
- Service areas (Urban agriculture at work)
- Play areas
- Food areas (vegetable, herb gardens, fruit/nut trees)
- Outdoor living room (an extension of your home)
- Porches
- Indoor plants

Some Plant Considerations
• Soil type and condition
• Plant water needs
• Plant sun and shade needs
• Plant height
• Annual or perennial?
• Type foliage desired
• High maintenance, natural growth, or somewhere in between?
• Blooming or non-blooming?

Tips for Successful Urban Agriculture
• Consult with knowledgeable sources
• Establish a budget
• Establish a plan within budget for each area where planting is to occur including plant type(s), soil needs, water delivery method and other considerations
• Plant your urban farm per instructions
• Maintain your crops through proper watering, pruning, care, etc.
• Enjoy the beauty of your urban farm
• If you prefer not to do it yourself, contact your local nurseryman/landscaper who will professionally assist you in obtaining your urban farm goals

 

Benefits of urban agriculture crops PDF

Oxygen
- In one year an average size tree “exhales” enough oxygen to keep a family of four breathing for one year.
- A turf area of just 50’ x 50’ releases enough oxygen in one year to meet the needs of a family of four.

Clean Air
- In one year an average size tree “inhales” 26 pounds of carbon dioxide.
- NASA scientists showed as little as one potted plant per 100 square feet of floor space can help clean air.
- Plants absorb nitrogen oxides, airborne ammonia, sulfur dioxide and ozone.

Rain
- Through transpiration, plants take water from the soil and return it to the air in a continuous cycle helping to create rain.

Cleaner Runoff
- Plants control runoff, slowing erosion and allowing water to be absorbed and returned to aquifers.
- Plant material cleans the water running off of city rooftops, sidewalks, streets and yards decreasing the amount of pollutants flowing into our rivers.

Shade
- Plants conserve energy – the difference between a shaded wall and un-shaded wall during a Texas summer averages 8 degrees – equivalent to a 30% increase in insulation.
- One tree strategically placed in a yard for shading a home produces a cooling effect equal to 10 room-sized air conditioners running 20 hours a day.
- Trees and shrubs strategically placed next to dwellings can reduce summer air conditioning costs by up to 50%.

Beauty
- Trees, shrubs, flowers and other plants provide both esthetic value and intrinsic value to property.
- Plants provide psychological benefits – studies demonstrate areas with trees and landscapes provide many positive attributes to those experiencing them.

Other Benefits
- Trees and plants in urban areas provide habitat in which a broad variety of wildlife thrives.
- Plants are noise filters.
- Provides us with natural playgrounds.

 

Water Efficient Irrigation… PDF

- Best for plants and yards
- Best for the environment
- Best for the pocketbooks
- In Texas, watering of plants and yards is an important part of any landscape management
program. When watering utilize these basic concepts for water efficient irrigation!
- Water when the plant needs it, not by the calendar.
- Water early in the morning when evaporation is minimal and winds are calmest.
- Set it and forget it is for digital watches, not irrigation systems!
- Install rainwater shutoff devices to avoid watering when raining.
- Proper irrigation means less run-off of fertilizer and chemicals for cleaner stormwater.
- Turfgrass and ornamentals develop deeper root systems with proper watering.
- Driveways and decks will not grow – do not water them.
- Mulch cuts down on watering and helps the quality of the soil.
- Check water delivery systems regularly to insure proper operation and water efficient irrigation.
- Success Tip: Too much water is as bad for the plant as too little water.
