Abstract
Description
Arabidopsis thaliana (Columbia) was exposed to 4 different soil types (100% sand, 50/50 sand and perlite, 50/50 sand/charcoal and standard potting mix) in the presence and absence of fertilizer. In the fertilizer treatment, the plants were exposed to a 50 ppm fertilizer at two and four weeks after planting. Leaf number and length of largest leaf were measured once a week throughout eight weeks of the experiment. Twice during the experiment, soil concentration of phosphates, nitrates, nitrates and pH was measured. Water retention was tested once in the beginning of the experiment each day for seven days. Most plants in the high fertilizer treatment died after the second treatment. The plants in the no fertilizer treatment grew slowly. The control plants, grown in potting mix without fertilizer showed the most growth. Only the plants grown in pure sand, without fertilizer, flowered.
