Waste Stream Assessment -

Estimate what percentages of your waste fall into these common categories.  Add your own categories if necessary.

___% Agricultural Chemicals ___% Plant Material
___% Packaging and Containers ___% Other 
___% Water and Soil Quality Issues  

Now look at where you can reduce waste, reuse materials or recycle.  Try to make use of environmentally friendly or easily manageable gardening and farming products when possible.  Consider alternatives to dangerous or difficult to manage chemicals.  Go to links for information on IPM Strategies (pest management). 

Use this checklist to identify possible problem areas.

Agricultural Chemicals

Pesticides and herbicides - Do You?

Keep product in original containers

Keep lids secure and closed tightly to prevent spills and evaporation

Store containers in an area where they won't corrode (not directly on the ground). Store over spill containing pallets when possible.

Know that any water contaminated with such waste becomes waste itself.

Teach students proper and efficient application and cleanup techniques.

Keep in mind that dry chemicals are safer to store and easier to clean up.

Buy only what you need.

Always follow recommended application rates.

Fertilizers - Do You?

Keep product in original containers.

Keep lids secure and closed tightly to prevent spills and evaporation.

Store containers in an area where they won't corrode (not directly on the ground). Store over spill containing pallets when possible.

Know that any water contaminated with such waste becomes waste itself.

Teach students proper and efficient application and cleanup techniques.

Keep in mind that dry chemicals are safer to store and easier to clean up.

Buy only what you need.

Always follow recommended application rates.

Consider testing the soil you intend to plant to determine the exact nutrient or fertilizer needs for your plot as a lab activity in itself. Interpret the results with the class. (Call the Extension Service for soil testing information.)

Plant Material

Dead plants and clippings - Do You?

Compost plant material for introduction into the soil. (Your local Extension office can provide you with literature and instructions.)

Choose composting over burning as a means of use or disposal.

Weeds - Do You?

Be careful handling weeds as they are a very serious environmental threat

Contact your local Extension office for information on noxious weeds in your area

Get local information on disposal and handling as they can vary from area to area.

Water and Soil Quality

Local water run-off - Do You?

Consider soil type in area of application. (Chemicals travel faster and easier through sand and gravel, so soil type may affect application rate.)

Consider distance to surface water and take care not to contaminate it.

Remember never to apply chemical when a rain storm may wash it all into a water source.

Mixing area - Do You?

Remember never to mix pesticides up slope from/or within 100 feet of a well

Mix near storage area to minimize the amount of transportation of bulk chemicals.

Always mix over some sort of containment basin or sealed concrete pad.

Packaging and Containers - Do You?

Re-use empty clean containers for storage of appropriate items

Return empty containers to the distributor for re-use where possible

Triple rinse empty chemical containers, using rinse water for application purpose and dilution of chemical.

Do not mix inappropriate chemicals even in diluted form.
