Soil Testing & Organic Fertilizer Recommendation Service

Don’t guess—test! Applying fertilizers and soil amendments without the guidance of a professional soil test is like driving downtown with your eyes shut. Applying too much of one nutrient can tie up others and wreak havoc on your soil biology. But even with test results in hand, which fertilizer do you choose and how much do you apply? Fedco to the rescue! We’ll send you a soil test kit and sampling instructions, plus a box to return your soil sample and test form to the Maine State Soil Lab. Please note that the lab’s methods are most appropriate for soils in the Northeastern US; if you live elsewhere, please work with a more local lab.

You’ll learn your soil pH, organic matter percentage, phosphorus, potassium, magnesium, calcium, sulfur, boron, copper, manganese, zinc, and available nitrogen, plus we’ll offer customized recommendations for how to correct any deficiencies or imbalances in your soil.

Customer Jake S. told us, “I followed [your] instructions in the spring. The garden thrived, I actually had full carrots this year, the garlic was huge and the spinach spectacular, all best-evers.”

Order A for annual vegetable crops and B for fruit tree orchards.

For best results, take samples during the growing season while the soil is warm. Please be patient! We are at the mercy of how busy the soil lab is at any given time. You will need to spend about $10 at the Post Office to ship the sample(s) to the lab. Each kit comes with one USPS flat-rate box, but two samples can fit into one box, which saves money at the Post Office if you have more than one sample.

Items shipping from our growing supplies warehouse take 2-4 business days to process.
