For our experiment, we had 4 rows of basil plants in two different trays. Tray 1 had soil that was made up of 50% loam and 50% clay and tray 2 had soil that was made up of 100% loam. In the tray that contained clay and loam, the plants started out growing well and we thought that was happening because the clay retained nutrients well. In tray 2, which was 100% loam, the plants also started out growing well as was expected, because loam is traditionally the best soil to use for growing plants. To our surprise, the plants in tray 1, which was the tray with half clay and half loam, grew very fast. After two weeks or so, the plants were at a height around 22 cm and were looking great! Unfortunately though, the clay eventually dried out and after a long 4 day weekend of not being watered, the plants died out. As the plants died out, the soil became really dry and looked like concrete. In the other tray that was 100% loam, the plants grew gradually and were nice and tall over the 8 week experiment. They eventually reached a height around 20 cm and proved that soil that was 100% loam is truly the safer and better call. If you are going to do any gardening, Mullanphy school suggests using loam!
