Extension Master Gardener℠ Volunteers in Cabarrus County Show Us How

EMG volunteers Gerri Harris and Renee Hedrick share the butterfly cycle with fairgoers.

At their booth at the Cabarrus County Fair, Extension Master Gardener℠ (EMG) volunteers spread the word about gardening resources available from NC State Extension. With an eye-catching display and friendly faces staffing the booth, EMG volunteers shared information, answered gardening questions and built awareness of the EMG program. The title of their booth, Diggin’ in the Dirt, captured this year’s theme: educating the public about soil.

For the most productive vegetable gardens and the healthiest landscapes, gardeners must investigate what lies beneath the surface. Soil acidity and nutrient levels vary widely across our state. EMG volunteers explained to fairgoers that soil testing is the best way to determine what nutrients your soil has and what nutrients your soil may lack, and if the pH of your soil needs to be adjusted.

While some gardeners are familiar with macronutrients such as nitrogen, phosphorus and potassium (referred to as N-P-K on fertilizer bags), soil pH and micronutrients also affect plant health and vigor. Fortunately, soil testing is an easy and inexpensive way to determine the nutrient status of your soil. In fact, for most of the year, there is no fee to submit samples to the N.C. Department of Agriculture and Consumer Services (NCDA&CS).

Soil sampling is a critical first step toward successful gardening.

Throughout the fair, EMG volunteers explained how to take a soil sample, passed out soil sample boxes and reminded the public that the boxes are available for pick up year-round at N.C. Cooperative Extension county centers. Once collected, soil samples should be mailed directly to the NCDA&CS for testing. Shortly thereafter, homeowners will receive a report in the mail with recommendations on how to supplement their soil to feed the types of plants they are growing.

Nutrient status is far from the only factor that affects soil and plant health. Soil texture and structure are also critical to healthy plant growth. Having a booth at the Fair gave EMG volunteers the opportunity to explain the process of soil testing, as well as display various kinds of soils and amendments, such as compost, that can be used to improve soil texture and structure.

But first, they needed to attract people to the booth. This was accomplished with a variety of interesting displays, including butterfly chrysalises that volunteers had collected. Over the course of the Fair, butterflies hatched before the eyes of curious children and adults alike, giving the EMG volunteers the opportunity to talk about insect life cycles and pollinators. A scavenger hunt also engaged families. Participants searched the booth for nature-related items and received a prize when finished. Children also enjoyed a planting activity that got them literally “diggin’ in the dirt.”

Hands-on planting activities engaged the kids.

EMG volunteer Gerri Harris describes the booth as an all-hands-on-deck affair, “It takes many volunteers to staff the booth throughout the nine-day event, for all the hours the Fair is open. And it’s a good way for new EMG volunteers to start to serve. We make an effort to pair new EMG volunteers with those with more experience.”
