Get all the dirt on compost


It might look like dirt, but these hands are holding compost created from common household wastes. Mixed in to the ground, compost adds nutrients to our soils.


How much do you think about the garbage you toss away? A little more thought along with careful sorting of our wastes can greatly reduce the amount of trash we bury in the ground. And much of that sorted waste can be turned into nutrient-rich compost that can augment the soils of our yards and gardens to give back a little bit.

Click through these pages to learn how composting works and how it can be used to make us all better stewards of our environment.

Check the case next to the wall to see composting action. Each tray shows a different stage of the composting process. Don't worry about any smell. Special filters keep any stink from getting out!!!

The garden probally smells bad because compost is sometimes old food. So that is why it smells bad.

We compost because it keeps us from having too much trash and once the compost sits for long enough it becomes fertizler for our garden! We love eating our fresh vegetables that are nourished from our own compost!

hello people. Ok, when you make compost hole put worms in it because, the worms will breake down some of the organics, and when they die they will become part of the compost too. When all the compost stuff is done, you can then put the new soil/dirt on your seeds and they should grow very VERY well.

It is hard, but rewarding to garden. Gardening can be made easyer by compost! So, use your old scraps and old fruit to feed your plant! Then you can have heathier, richer, well nurishing fruit and vegies
