No. 4.] NITKOGEN AND FERTILITY. 201 



bacteria. If deficient in minerals, you would have to add 

 some phosphoric acid and potash to it. 



Mr. Howard. What is the value of the nitrogen which 

 is in the clover crop as grown ? 



Dr. Woods. You mean as a fertilizer, if it were plowed 

 under green? Organic nitrogen in that form is quite 

 readily available for plants. If it goes under ground, there 

 are usually ferments enough that commence and break it 

 down very speedily. I shouldn't hesitate to say, of green 

 clover plowed in, that the nitrogen would be worth as much 

 as that of cotton-seed meal, for instance. 



Mr. Henry A. Turner (of Norwell). Suppose it isn't 

 plowed in, but allowed to remain on the surface ; do you get 

 the benefit of the nitrogen ? 



Dr. Woods. Never plowed in? 



Mr. Turner. Not to plow it in at all. 



Dr. Woods. Why, you will get the benefit from that 

 which is accumulated in the roots, but you will get but very 

 little benefit from the tops. 



Mr. Sessions. The Board of Agriculture and other 

 friends who have met here and enjoyed these meetings are 

 under extreme obligations to the two orfflinizations which 

 have invited us here, the Worcester County Horticultural 

 Society and the Worcester Agricultural Society. There are 

 very few organizations that can offer such beautiful accom- 

 modations as has the horticultural society to us here. This 

 hall is one of the very best in the city for meetings of this 

 kind. But I want to emphasize also the fact that the loca- 

 tion of this meetino- is in the midst of a communitv that 

 takes an interest in such meetings, as is proved b}^ the at- 

 tendance we have had here through these three days. But 

 I arose to move a hearty vote of thanks to the two societies 

 as hosts of this Board and its friends in the invitations which 

 have been extended to us. 



Mr. Pratt. I wish to second the motion by saying that 

 I believe we understand that everything has been done by 

 the citizens and the societies to make our stay here pleasant. 



Unanimous vote.
