Why do coffee grounds make good fertilizer?
what if I’m doing a science fair project and my cup doesn’t have any worms.
Should I use coffee grounds as a varible?
or should I just use fish food as a varible? How does fish food make a good fertilizer?
Coffee grounds are a low-level source of nitrogen, having a fertilizer value of around 2.0-0.3-0.2, as well as a minor source of calcium and magnesium. Post-brewed coffee grounds are reported to be slightly to highly acidic, depending on the source, but no more so than peat moss. So, one could apply them to the soil for acid-loving plants, such as rhododendrons, azaleas and blueberries, etc. Or, you could spread them out over a larger garden area to minimize the pH effect. It’s difficult to make a specific recommendation for an application rate, but it’s always better to err on the lighter side, since the pH can be variable. A rate of 10 pounds (dry weight) per 1000 square feet would be conservative.
TO ANSWER YOUR QUESTION, MORE SPECIFICALLY:
Composting is also an excellent method to recycle the grounds, which have a carbon-to-nitrogen ratio of around 20:1. Use the grounds as you would green, leafy material, mixing with some dry, brown plant materials in the compost. The Environmental Protection Agency suggests adding no more than 25 percent volume coffee grounds. WORM COMPOSTERS report that coffee grounds are an excellent food source for the little critters. Again, be sure to MIX THE GROUNDS with brown materials (like soggy leaves), even in the worm bin.
