Question

studied how soil management affects bacterial production of B-glucosidase, an important enzyme that that is critical for metabolism (breakdown) of plant material in the soil, which can affect soil quality - greater breakdown of plant materials (via greater activity of B-glucosidase) generally leads to better soil quality. Below are some results from the study: 6-glucosidase activity is measured as the number of transcript copies per gram soil (y axis = experimental) (a 2 gram scoop of soil), and the effect of soil type was analyzed via one-way ANOVA. Chart: Beta- glucosidase activity for tillage (I), nontillage and no-cover (NC), cover crop plus herbicides (CH), and cover crops plus mower (CM) soils (F3,2=46, P 0.05 for the Tukey test). A) what could conclude only from the results of the F test if we set alpha at 0.05? B) state the null hypothesis for the ANOVA applied above C) achieving the highest Beta - glucosidase activity in their soil, which soil treatment should be use?
