A variety of materials such as lawn clippings , fallen leaves , chipped prunings , and compost will add organic matter to the soil . This research will involve organic synthesis , physical methods , and computational chemistry . Presentations will include organic certification , soil management , livestock management , horticultural production , agronomic production and biological controls . " Along with atmospheric measurements , field researchers will sample organic material from the ground to understand how carbon is taken up and released by trees , dead wood , roots , brush , and other material .
