1920.] The Value of Lupins on Poor Light Land. 991 



The last characteristic is doubtless due to the large quantity 

 of nitrogen which they accumulate from the air, and to their 

 extensive root system which opens up the soil to less strongly- 

 rooted plants. The question of the commercial utilisation of 

 lupin seed, however, has not yet, as far as the writer is aware, 

 been investigated in this country. 



Conclutlon.— After a consideration of all the facts observed 

 in the cultivation of lupins the writer has come to the conclusion 

 that their value as a means of improving and reclaiming poor 

 light land is not yet sufficiently appreciated in this country. 

 The effect of a crop of lupins upon the succeeding crop is 

 really astonishing. Lupins grow with surprising luxuriance 

 upon poor, blowing sand, which will grow practically nothmg 

 else but rye. The high cost of cultivation is causing farmers 

 to consider carefully what proportion of their land it will pay 

 them to cultivate. It is, therefore, of the greatest importance 

 that any crop which seems to possess properties which make 

 its cultivation on certain soils especially suitable should be 

 carefully studied, and the results obtained from its cultivation 

 made known as widely as possible. 



In conclusion, the writer wishes to express his indebtedness 

 to the gentlemen mentioned in this paper, for the very valuable 

 information they have so kindly given him, and also to Mr. 

 Fred Smith, of Woodbridge, who has kindly read through this 

 article. Mr. Smith has had extensive experience with lupins, 

 and has expressed his agreement with the general conclusions 

 arrived at.
