Abstract
County extension agents interpret soil pH and fertility tests to clientele on a routine basis. These interpretations require tailoring the information to the clients’ landscape, needs, or situation. In many cases, clients submit soil samples to solve a problem or plan a landscape. Yet agents typically count these consultations only as client contacts. However, information obtained from soil pH and fertility tests can be used to select appropriate plants, correct nutrient deficiencies, and apply fertilizers or soil amendments. To learn how homeowners use the information provided to them through soil tests and extension agents, we created and distributed a survey tool to measure potential outcomes of this information. Results show that more than 90% of survey respondents are satisfied with the quality of service, 80% replied they know more about soil pH, and 50% responded they changed their fertilizer practices, applied lime or sulfur responsibly, and stated the pH information will help them choose appropriate plants. More than 60% of survey respondents reported the soil test information saved them money and time. Results of this survey demonstrate that extension agents can use survey tools to quantify homeowners’ use of soil pH and fertility test interpretation on their landscape practices. The potential outcomes from appropriate plant selection, responsible use of soil amendments, and time or money savings can be useful to extension agents quantifying their programmatic efforts.
