It’s spring planting season, and you’re itching to get out and get your hands dirty! Adding compost to your garden is a great way to improve your soil and increase your bounty. Here are some tips to get the most out of your plot.
Testing your soil
Before you begin, it’s always a good idea to test your soil. Urban soils can have contamination issues. Testing your soil will make you aware of existing contamination and help you make decisions about interacting with your soil based on the results. Testing your soil also gives you information about the amount of organic matter and nutrients available in your soil, which can inform how you manage your soil fertility over the years.
Neighbors Allied for Good Growth is hosting free soil testing workshops at the McCarren Park Greenmarket on May 6th and 13th. Bring your soil sample in a ziplock bag for testing by Urban Soils Institute. More info here

Amending your soil
Compost is a great way to improve the health of your soil. It provides structure and nutrients for vegetable gardens, lawn applications, potted plants, and street tree beds. But no matter where you are using the compost, you want to think long term.
Chemical fertilizers contain a mixture of nitrogen, phosphorous, and potassium in a relatively pure form, which offers plants a quick jolt of nutrients. Whatever the plants can use is soaked up immediately, and any excess can wash away.
Compost contains the same nutrients fixed in stable organic compounds. Plants have to work a little harder to access the nutrients with the help of micro-organisms, but this allows them to gather nutrients as they need them. Since the nutrients are bound up in compost aggregates, they remain in the soil for longer periods. The result is a more controlled release of nutrients to the plants throughout the growing season and from one season to the next.
Because of this slow release of nutrients, we recommend that you add compost sparingly. You will build up the structure and health of your soil over many seasons. Here are our suggestions for compost application rates:
|Location||Type of compost||Annual Application|
|Garden plots and beds||Screened||1 inch|
|Lawn application||Screened||1/8-1/4 inch|
|Tree care||Unscreened||2 inches|
|Containers or Filling Raised Beds||Screened||1/5 of the overall volume|
