CONSERVATION OF THE SOIL.
Hon. James J. Hill, of St. Paul, Minn.
Just as all industry depends upon the production and increase of the fruits of the earth, so all other forms of Conservation must be held subordinate to the preservation of the productivity of the soil. To preserve and defend the public health, to see that human beings are brought into the world and kept there under favoring conditions, and to lengthen their term of life will but add to the total of human misery unless they are well fed and housed and clothed. For this, as for the material of all their varied activities, they must come back in the last analysis to the soil. Earth is the mother not only of mankind but of all human industry.
In the years during which the necessity of this most imperative form of Conservation has been the subject of my thought and the theme of most of my public utterances, much has been accomplished. The interest of the public is awake. It is not necessary any longer to urge a Conservation movement, but rather to direct the energy already enlisted in its behalf into wise channels. While the farmer is still subject to some unfavorable legislative discrimination, we know that his prosperity must be made a first object before prosperity can visit others. The progress of the farm is put first in many schemes of public improvement where, a few years ago, it would have been mentioned perfunctorily if at all.
Education in agriculture has made much progress. The number of institutions teaching agriculture increased more than sixty per cent. in nineteen months. They had ten per cent. more students in agriculture in 1910 than in 1909, and more than eight times as many students taking the teachers’ course in agriculture. Colleges and high schools give place to some form of agricultural instruction; and the necessity of fostering soil Conservation is recognized today as never before.
What we need to do at once belongs rather to the practical than to the theoretical side of Conservation. There is little reason to doubt that the farmer of the future should be a highly intelligent man, commanding from his acres crops that are far beyond those of today in their abundance. But the present generation may and should do far better for itself, in its own time, while it is also preparing the way for the more careful and productive agriculture which should follow.
I use intentionally the words “careful” and “productive” instead of the word “scientific,” as applied to soil treatment and crop raising, because they express the simple and easy processes within the reach of men of the present generation as well as the new; because they avoid a misleading implication that attaches to the word “scientific.” It is true that the best methods of soil treatment and crop growing are scientific; but they require only that form of popular science which is within the comprehension and use of every farmer.
The essentials of soil Conservation have been known for centuries. They were practiced in Babylonia, just as irrigation was resorted to there on a splendid scale. They have been the property of the Chinese for four thousand years, and maintained there a dense population in spite of croppings so frequent and severe that it would seem impossible for any soil to stand such treatment without exhaustion. The latest bulletin of the best agricultural institution is scarcely more instructive or helpful than a study of the “forty centuries of agriculture” included in the experience of these skilled and laborious people of the Orient.
The soil is a living thing, and must receive the treatment due to all organic and vital beings from which we expect service or tribute. The first requisite is that the individual man learn with what manner of soil he is dealing. There is now an agricultural college or experiment station within the reach of every farmer in the country. Some are and all should be equipped for a scientific analysis of all soils submitted to them. From this the cultivator may learn the first two things indispensable to any intelligent conduct of his industry: First, to what crops his land is best adapted; second, what elements of fertility have been drawn from it so lavishly that they need to be restored. This information having been given by competent authority, every farmer may do all the rest for himself.
There is no secret and no mystery about the processes involved. If farmers will rotate their crops, fertilize plentifully and intelligently, keep live stock to diversify their industry, refresh the land and utilize waste products, and cultivate thoroughly and frequently, the problem of soil Conservation is solved. The earth has been kept as productive for thousands of years as it was when it produced its first crop of cultivated cereals wherever these few and simple conditions have been observed. If seed is carefully selected, after a test for germination, and the practices mentioned are followed, there is no reason why the yield per acre of the principal crops of the United States should not equal those of England, Germany or many other countries which produce twice as much as we do with far inferior natural advantages.
