Incidentally this soil treatment seems to give it about allthe plant food that it can use and it puts forth a rank, darkgreen growth that would do credit to a green bay instead of agreen apple tree. A glance at Figure 102 will show the type ofgrowth to be expected. Now suppose that more nitrogen has been added, particularlyslowly available nitrogen, like barn manure or tankage. The.

If thedamage is less we are likely to find injury around the trunkof the tree, as is shown in Figure 103. In this case the bark waskilled only part way around and the tree survived, but it is like a down to work is coiicorncd. man with one lung so far as gettin
