In cooperation with the Wisconsin Potato and Vegetable Growers Association and the UW Hancock Agricultural Research Station, AgSource Laboratories is offering free GAP water sample pick-up this summer.


 "A crop may still look good if there is excess or inadequate nitrogen," said Dr. Jim Friedericks, AgSource Laboratories' Outreach and Education Advisor. "Even though there are no visible signs, your yield may have been impacted."

 AgSource Laboratories is excited to introduce the Soil Health Assessment. This new soil report combines the chemical and physical results of traditional soil testing with biological assessments of microbial activity to provide a measure of the quality of the soil. In general, a higher score means a more healthy soil, and improving the score over time indicates that management practices are benefiting the soil and improving soil health. 

Manure is a very important nutrient resource. With proper management, it can also improve soil health by suppling nutrients to microorganisms and improving water infiltration and retention by increasing the amount of organic matter in the soil. But before heading to the fields and applying manure this fall, consider submitting a manure sample.
