"Recent investigations at the In- 

 diana station show that in some cases 

 where the tiltli of the soil had been 

 improved by the introduction of vege- 

 table matter, and where there is an 

 abundant supply of ordinary plant 

 food, crops failed to thrive because of 

 the presence of aluminum nitrate. It 

 was shown, however, that upon the 

 addition of lime, the alumina is pre- 

 cipitated, the nitric acid combines 

 with lime, and the plants then thrive 

 splendidly. 



Raw Rock Phosphate. 



"Certain speakers and agricultural 

 writers in the Middle West have desig- 

 nated fertilizers as 'stimulants,' thus 

 creating the false impression that 

 their effect is but temporary and that 

 the after-effects from their use are 

 bad. This is absolutely misleading to 

 the public and is nothing short of an 

 attempt to create prejudice without 

 the least justification for doing so. In 

 the Middle West much attention has 

 been called to raw rock phosphate and 

 speakers from that section have even 

 come into New England and recom- 

 mend its general use here. It is of 

 special interest, therefore, to note that 

 the director of the Ohio station as 

 well as the investigators at the Ten- 

 nessee station, who are close to the 

 source of raw rock phosphate, hold 

 that superphosphate is more economi- 

 cal for use in their states than the 

 raw untreated material. Results at 

 the Rhode Island station in the earlier 

 years of the experiment, when like 

 money values of different phosphates 

 were used, further substantiate the 

 results as reported from Ohio and 

 Tennessee. 



"Experiments by Loew show that it 

 is sometimes of great importance to 

 add lime to soils for the purpose of 

 counteracting the effects of an un- 

 usual amount of magnesia. There 

 may also be cases where the addition 

 of magnesia to a soil may be benefi- 

 cial on account of the lime being in 

 excess. The requirements in these 

 particulars vary with different plants. 



Usefulness of Soil Disinfectants. 



"Interest has been awakened in the 

 subject of the treatment of soils by 

 the fact that carbon disulphide, to- 

 luene and various other soil disinfec- 

 tants have been found to be highly 

 beneficial. Accordiu'g to the results 

 at the Rothamsted Experimental Sta- 

 tion, this is due in some cases to the 

 destruction of microscopic forms of 

 animal life which feed upon the use- 

 ful bacteria. When these animals are 

 destroyed the bacteria increases 

 enormously with marked benefit to the 



soil. Investigations in Europe and at 

 the Agricultural Experiment Station 

 in Rhode Island show that sodium, if 

 present in fertilizers, whether as ni- 

 trate of soda or as common salt in as- 

 sociation with muriate of potash and 

 kainit, is of use to certain plants if 

 the supply of potash is insufficient, 

 whereas there are cases of plants 

 which show but little, if any ability 

 to benefit by it. 



"Recent utilization of great water- 

 falls for the generation of powerful 

 electrical currents has made it pos- 

 sible to combine the gaseous nitrogen 

 of the atmosphere in such a way that 

 calcium cyanide, calcium nitrate, am- 

 monium sulphate and ammonium ni- 

 trate are now coming on the market 

 as plant foods. The nitrogen of the 

 air surrounding the earth, which 

 could formerly be utilized through the 

 aid of leguminous plants, may now, 

 therefore, be made our priceless pos- 

 session for the nutrition and mainte- 

 nance of the human race." 



FLORICULTURE DAY AT AM- 

 HERST. 



Section 4, which is devoted to flori- 

 culture, had a busy day, with every 

 period taken by a lecturer. Professor 

 A. H. Nehrling, who has but recently 

 taken up his work as head of the 

 floriculture department at this college, 

 was the first speaker. His subject was 

 "Opportunities in Floriculture." In the 

 absence of Harry A. Bunyard, Asa G. 

 Kinney of Mt. Holyoke College, spoke 

 on Mushroom Culture. 



T. D. Hatfield of Wellesley was the 

 concluding speaker of the morning, 

 and his subject was Raising Plants 

 from Seed. He brought out numerous 

 valuable points in regard to the proba- 

 ble effects of pollination and acclimati- 

 zation of plants grown from seeds. 

 Eber Holmes was the first afternoon 

 speaker, his subject being Outdoor 

 Rose Culture. He first discussed the 

 varieties of roses best suited for out- 

 door planting and the kind and type of 

 plants which should be bought. Fac- 

 tors of location, soil, methods and 

 time for planting, methods of culture 

 during the growing season, care dur- 

 ing fall and winter were treated each 

 in its turn. He discussed the different 

 insect pests and fungus diseases, and 

 methods of combating them. In clos- 

 ing he called attention to the profits 

 which may be realized in growing out- 

 door roses, as well as those grown in 

 greenhouses. E. J. Canning gave a 

 general practical talk on "Methods of 

 Improving Plants." He discussed the 

 three principal factors of amelioration 

 of plants, cultivation, selection and 

 crossing. 



The concluding talk of the day was 

 by Professor Nehrling on Glass 

 Houses in the Middle West. He called 

 attention to the fact that architectural 

 features as well as details of construc- 

 tion must be considered in planning 

 conservatories for park or private use. 



There were over 1000 visitors who 

 attended the third session of Farmers' 

 Week at M. A. C. in spite of the 

 weather. W. H. Hatfield.
