Wintertime Testing

Thank you to all our customers for your great interest in our testing services during 2014. We matched or exceeded record sample numbers for soil, compost, and manure testing.

The easiest way to take advantage of our Soil Testing Winter Discount is to sample your soil before the ground freezes, set samples aside to air dry, and send them in between January 1 and February 28. During this period the charge for a Standard Soil Test is just $12.

High tunnel growers are already sampling ahead of late winter/early spring planting dates. High tunnel recommendations were substantially upgraded in 2014 to compensate for higher productivity and nutrient demand. Ongoing research will further refine these recommendations.
