This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Designer rootstocks enable fruit trees to thrive under otherwise unbearable conditions, providing strong anchorage and defending against biological and nonbiological stressors. But what role does the root microbiome play in this assistive act? To find out, researchers used 16S rRNA sequencing to examine the rootstocks of Valencia orange trees in Florida. Results showed that the genetic makeup of different rootstocks determined how the root microbiome responded to compost treatment. The aspects of the root microbiome that were rootstock- specific included bacterial abundance, diversity, and community composition. These findings suggest that specific bacteria drive changes in nutrient concentrations accessed by different rootstocks. Understanding this intimate relationship is important to supporting overall plant health and could inspire research into how root microbes might affect other parts of trees..."

Over the course of three sessions, students act as agricultural engineers and learn about the sustainable pest control technique known as soil biosolarization in which organic waste is used to help eliminate pests during soil solarization instead of using toxic compounds like pesticides and fumigants. Student teams prepare seed starter pots using a source of microorganisms (soil or compost) and “organic waste” (such as oatmeal, a source of carbon for the microorganisms). They plant seeds (representing weed seeds) in the pots, add water and cover them with plastic wrap. At experiment end, students count the weed seedlings and assess the efficacy of the soil biosolarization technique in inactivating the weed seeds. An experiment-guiding handout and pre/post quizzes are provided.

Throwing items away is a part of our daily life. Most people are used to throwing away their food and recycling their plastic bottles; however, there is more to know about properly disposing of our waste. In this seminar, you will learn to differentiate between trash, recyclable, and compostable items. By the end of this seminar, you will be able to use deductive reasoning skills to determine the proper waste receptacle for items in your everyday life.Standards 3.4.5.B2Describe how waste may be appropriately recycled or disposed of to prevent unnecessary harm to the environment.

This activity is a lab investigation where students design an experiment to create rich soil using organic matter, dirt, newspaper and red worms.
