Soils

These links will guide you to a thorough understanding of soil science, including timely issues such as soil conservation goals (minimal till, minimal bare soil), understanding soil temperature, choosing and applying lime, and understanding the effects of additives and mulches on soil. There are links for students and teachers, and links for soil news. Although the soil fact sheets were gathered from respected sites around the country, they are broadly applicable, including to soils in the Northeast. As usual, for specific information, the best place to start is with fact sheets from University of Connecticut and the Connecticut Agricultural Experiment Station.
