Tracy Allen, supervisor, UMass Soil Laboratory, explains that soil properties are not going to change much in the winter because soil processes slow way down in the cold, so soil test results and recommendations that offered this fall will be accurate and useful for the whole growing season in your garden next year.
In the spring, the lab is deluged with requests and that can cause a backlog. "It could take twice as long to get your results back and that is valuable time in the planting season," Allen said. (MassLive 11/1/17, News Office 11/1/17, Recorder 11/4/17)
