If you've been thinking of testing different ways to grow plants, but don't know how to do a test that produces scientifically valid results (i.e., results that really are significant or correlatable), this book is for you. Luckily, the way Levitan explains the process, "scientifically valid" doesn't have to mean tedious or time-consuming. She suggests ways to start simply - from test design through execution and analysis. The chapters I benefitted the most from were those describing soil characteristics, test design, data collection, and data analysis. Levitan makes some good suggestions for potential tests (i liked the one on comparing germination, other factors in plants started during different lunar phases), and provides pragmatic advice on how to conduct your test (if the test entails too much work on your part, you may not follow through with the data collection and analysis, so try to design a test that fits into your schedule). I found the book a good introduction to doing research at home. In fact, when I did a search on this topic, this was the ONLY book I found on doing garden research at home. If you're interested in this kind of topic, I definitely suggest adding this to your library.
