Before we leave the results of this year, it should be observed that on 8a, 5,000 lbs. of cut straw and chaff were used per acre. I do not recollect seeing anything in regard to it. And yet the result was very remarkable—so much so indeed, that it is a matter of regret that the experiment was not repeated.
This 5,000 lbs. of straw and chaff gave an increase of more than 10 bushels per acre over the continuously unmanured plot.
“Good,” said the Deacon, “I have always told you that you under-estimated the value of straw, especially in regard to its mechanical action.”
I did not reply to this remark of the good Deacon. I have never doubted the good effects of anything that lightens up a clay soil and renders it warmer and more porous. I suppose the great benefit derived from this application of straw must be attributed to its ameliorating action on the soil. The 5,000 lbs. of straw and chaff produced a crop within nearly 3 bushels per acre of the plot manured every year with 14 tons of barn-yard manure.
“I am surprised,” said the Doctor, “that salt did no good. I have seen many instances in which it has had a wonderful effect on wheat.”
“Yes,” said I, “and our experienced friend, John Johnston, is very decidedly of the opinion that its use is highly profitable. He sows a barrel of salt per acre broadcast on the land at the time he sows his wheat, and I have myself seen it produce a decided improvement in the crop.”
We have now given the results of the first eight years of the experiments. From this time forward, the same manures were used year after year on the same plot.
The results are given in the accompanying tables for the following twelve years—harvests for 1852-53-54-55-56-57-58-59-60-61-62 and 1863. Such another set of experiments are not to be found in the world, and they deserve and will receive the careful study of every intelligent American farmer.
“I am with you there,” said the Deacon. “You seem to think that I do not appreciate the labors of scientific men. I do. Such experiments as these we are examining command the respect of every intelligent farmer. I may not fully understand them, but I can see clearly enough that they are of great value.”
