Distribution of roots of certain Distribution of roots of certain tree species in two Connecticut soils distributionofro00gari Year: 1942 126 Connecticut Experiment Station Bulletin the field, and are shown on Figures 7, 8 and 9, some of the above des- cribed differences can be seen. In addition to these differences, more biological activity, as evi- denced by a greater number of earthworm and insect holes, was ob- served in the Charlton than in Merrimac soil. However, the activ- ity of earthworms was confined to a shallower depth in the Charlton soil, owing to poor drainage and aeration conditions and heavier tex- ture. LABORATORY METHODS The laboratory analyses of soil samples collected in the field were divided into three parts. The first consisted in aggregate and physi- cal analyses of the special samples collected for this purpose from the two soils under investigation. The second part related to chemi- cal analyses of the general samples collected by horizons from the two soils. The third part consisted of a limited number of tests on soil samples collected in pairs according to root concentrations, tree species and soil horizons. General soil samples were also included in the third set of tests. «nnaBBMIKnBB«M|njjB /•«
