Mr. Potter: I want to state some experience I have had and when Mr. Reed talks, I wish he would give me some information. I set out some pecan trees on my lawn in the front yard, and of course there is not much cultivation there except around the trees. It is like most other lawns in southern Illinois, mostly clay and what other soil we put on top. Now the clay is very hard and in setting the trees I had my man dig a hole three feet deep and two feet across and in setting the trees I packed good dirt around them. The question is how should I feed those trees? I have put barn manure around them and they are now growing and doing very nicely, I want to know if I have pursued the right course.
Mr. McCoy: I believe this question of growing trees in fence corners and on hillsides is not so large a question. The main thing is to give them plenty of water. There is very little land in the Mississippi valley that won't grow pecan trees or most any other kind, if you will give them sufficient mulch and plenty of water, because they take their food in the form of soup. Unless they have water, they won't grow. I believe the best cultivation you can give a tree of any kind is a good mulch of straw and manure. You that have had experience in this part of the country know that is the best way to cultivate trees.
I grew a peach orchard once in one year, but I have quit that, I have learned better. It is simply a question of water and plant food. If you will mulch any kind of a tree, nut tree or any kind, with ten or fifteen inches of straw and stable manure, you will have a steady growth from early spring until late in the fall, and it will make a strong tree.
Professor Smith: While we are waiting for Mr. Reed I want to take up Mr. McCoy's soup suggestion. Water doesn't make good soup without something in it. Experiments show that you can mulch ground in some places and not wake up the tree, but fertilizer will wake it up the first year.
Mr. Potter: What kind of fertilizer did you use?
Professor Smith: One must experiment to see what his land is short on. Sometimes you can fertilize your trees without any result. Sometimes potash will not do any good and sometimes it will. You will have to see what your ground needs. For young apple trees I found in my particular situation that nitrate of soda is all I want. I have what is called a Porter's clay soil on the Blue Ridge Mountains of Virginia. I use that and then my trees get busy and grow. They make rapid growth even the first season with a handful of nitrate and for my three year old trees half a pound is enough. That is what my soil seems to need and we must use what the soil is short on. That is my interpretation of my situation and it works.
The President: Who can tell us whether nitrate of soda is good for nut trees? Can you, Mr. Simpson?
Mr. Simpson: In the South, we do not think so.
The President: The reason I asked, is that I have been studying that. I wrote Mr. Potter a letter suggesting that he use some on his young nut trees to see what it would do, and later I found out that all through the South it was not regarded as desirable. It seems they claim it starts pecan trees into an active growth but when they stop they make a very sudden stop and don't start growing any more. I want to get this in the record right here. You understand that is the general belief throughout the South, do you not?
Mr. Simpson: Yes sir, it is not considered good.
