Nutrients are at the root of success
By Peter Hull
Growers and members of the public sampled 25 seedless watermelon and 12 mini-watermelon varieties at the Edisto Research and Education Center’s Watermelon Field Day on July 8.
A training session on nutrient transfer from the soil to roots by plant pathologist Christina Wells described how plants use nitrogen to make proteins, enzymes and DNA. They use phosphorous to make DNA, cell membranes and energy-transport molecules. Potassium activates enzymes and maintains water balance in plants.
“These are the building blocks of plants,” Wells said.
Other presentations included a fungicide update and a demonstration of how soils hold water, as well as field research projects and variety trials. Field discussions included how to control insect pests, tools to measure soil water and a presentation on the Gravity Flow Drip Irrigation system. Certified Crop Advisor and Pesticide License credits also were offered.
