Wouldn't the soil density affect the root system?

  Yes. There aren't two root systems identical. I assume that this plants were cultured in a sandy or hydroponic mix. But the main goal is the generalization and to know how long roots can grow. For trees they wanted to know also if roots can grow up the hill against gravity (they do it all the time). This is useful to understand how stable is the structure and how useful to fix soil in place and fix erosion processes. The dune melon root is particularly funny. You can almost hear the root sniffing water right and left in the Namibian desert
