My raised bed vegetable gardens (10 years old) are not doing as well as usual. I think I need the soil tested. The soil was originally well composted horse manure which has been excellent and is readily available. Soil on our farm usually benefits from lime, and I'm thinking of putting some on the raised beds this fall, but think a soil test might be smart. I need to know how to do this and where to take the sample. Thank you.
Thanks for your soil testing question. Over time planting the same vegetables in the same garden space can deplete nutrients and change PH values, so prior to adding a nutrient such as lime, a soil test will measure and confirm any deficiency correction.
