X-Ray Fluorescence Soil Assessment
On April 28, 2014, two soil scientists (Richard Shaw and Edwin Muniz) from the United States Department of Agriculture Natural Resources Conservation Service (USDA NRCS) tested our soil for various trace metals. Although we knew our soil was pure, we were curious about this fantastic complimentary service offered to community gardens and now have a thorough and informative report to share with all our members. Levels of all screened metals, including arsenic and lead, were found to be within acceptable range for growing food crops.
To match your specific plot to a sample ID, please refer to this spreadsheet. Each plot was tested at two depths; surface (identified by an "a" next to the ID number) and subsurface (identified by a "b" next to the ID number).
Laboratory Soil Testing
How do you know if your soil has the right nutrients? Or the best way to amend it? Quite simply, you'll need a soil test. Soil tests are an inexpensive way to really get to know the dirt on your dirt.
One source for a soil test kit is the Rutgers Extension Office located at 314 State Route 12, Bldg. 2 in Flemington. Their standard test will cost you $20 (plus the postage to mail it) and you'll learn your exact pH level and availability of vital growing nutrients. Soil scientists will dispense advice on fertilization and amendments specific to your soil's needs. Curious minds need not stop there because additional tests can be run!
Organic Matter
Whether you decide to have your soil tested or not, you should still add a bit of organic matter to improve your soil's fertility, water-holding capabilites and structure. This is a routine you can practice annually. A few sources of organic matter are compost, manure, and leaves.
Learn more about how organic matter can improve your soil.
pH
pH is measured using a scale from 1 to 14. 7 is neutral, less than 7 is acidic and greater than 7 is basic. Most of our garden plants love a neutral soil around 6.5 because that's when nutrients in the soil are most readily available for healthy growth.
Our heavy clay soil in Hunterdon County is often slightly acidic and can be corrected using lime. But don't take our word for it; a soil sample test will confirm your very specific pH and provide you with amendment suggestions if your level is too high or too low.
