VOL. VII. No. 8. The efficiency of individual experiment stations, as well as the general usefulness of agricultural researches, will often be best promoted by making some one line of work the center about which all the other work of the station shall be grouped. The coöperation of investi gators in different branches of agricultural science may thus be secured. The station will naturally reach a preeminence in its chosen line, and become more or less an authority on this subject. The rela tions of the different parts of the inquiry to each other will be more clearly brought out. There will be a tendency on the part of each worker to consider how his own researches may be aided by suggestions growing out of the work of his colleagues. Most of the problems of agriculture are complex. Their solution is to be sought through the combined efforts of investigators in various sciences. Thoroughly trained specialists working together in accordance with a well-matured plan are most likely to achieve satisfactory and permanent results. As scientific effort in behalf of the arts and industries of life is developed, the principle of organization which has been found so effective in practical affairs will no doubt be found to apply equally well in this field. The agricultural experiment stations are already possessed of an organized life. It only remains to strengthen and develop this, give it a more perfect form, and direct its energies more fully in definite lines. Concentration and combination of effort will give vigor and effectiveness to these institutions for the uplifting of agriculture. One of our experiment stations has made the study of commercial fertilizers the central feature of its work. A part of its business under a State law has been the analysis and control of such fertilizers. The fertilizer markets have been closely observed, the value for fertilizing purposes of various refuse materials and by-products has been determined, and economy in the use of fertilizers has been a subject of special study. Home mixing of fertilizers has been popularized, and the advantages from this system have been illustrated in many trials. at the station and on private farms. The effects of fertilizers on the growth of different plants have been tested by laboratory and field experiments. The composition of plants grown with the aid of differ ent fertilizers has been determined. Careful studies of methods of analysis, including attempts to devise special apparatus, have been made. Hardly a phase of the general question of fertilizers has failed to receive attention, and the development of the station from the first has been very largely along this line. The success which has attended this station is a striking illustration of the good results of such concentration of effort. Irrigation brings with it a large number of important problems, and presents an attractive field for the combined efforts of different scientists. The engineer, physicist, meteorologist, chemist, botanist, vegetable pathologist, horticulturist, and agriculturist may all find plenty to do for a long time and can work all the more effectively if they work in unison. The waters, soils, and plants need to be studied in connection with inquiries regarding the methods and effects of different irrigation systems. The stations located in the regions where irrigation is the foundation of agriculture should esteem themselves fortunate in having their lines of work predetermined by nature. The vastness of the interests at stake should naturally stimulate them to the most earnest and thorough work. The newness of agriculture in many of these regions in itself should provoke greater activity in the effort to estab lish right lines of practice founded on correct principles. The great number of problems may require not only coöperation within individual stations, but also coöperation among stations in the irrigation region. It is hoped that this matter will receive the earnest consideration of the communities most deeply interested in the successful application of irrigation to agriculture, and that the representatives of the people associated in any way with the experiment-station enterprise will use their influence to bring about such conditions at the stations as will enable them to do their most effective work along this line. In this connection some investigations on the physiological rôle of water in plants, made in France by E. Gain, an account of which was given in the Record (7, p. 366), are quite suggestive. Hitherto comparatively little has been done in the study of plants grown under irrigation. Too often plants are irrigated with no reference to their requirements. The problems relating to the best times for irrigation and the amount of water to apply so as to secure the proper correlation of plant growth and economy of water supply are of the highest importance. In studying these questions numerous experiments should be conducted with different plants under various conditions, as a few trials with a limited number of plants will not serve as a basis for broad generalizations. The purpose for which the plant is grown must also be taken into consideration, a different quantity of water seeming to be required for seed production and vegetative growth. |
