EXPERIMENT STATION RECORD. 



Itoot iiodnles were foniid to be especially rich in nitrogen. 



"lu one case the light (•()h)re(l and active nodules contained 5.55 per cent nitro- 

 gen, while the dark colored and older ones from the same plants contained 3.21 per 

 cent. . . . 



"The mixed nodules, both active and inactive, from another lot of plants con- 

 tained 4.()0 ])erccnt nitrogen, while 100 parts of the entire roots contained 2.21 parts 

 of nitrogen." 



Proximate and asli analyses of clover grown in different parts of the 

 State are tabulated. From the results of these analyses and of soil 

 analyses reported in Bulletin 30 of the station (E. S. E., 5, p. 857), the 

 writer conclndes that the failure of clover on certain soils is due rather 

 to the want of proper mechanical condition of the soil than to the 

 absence of any chemical constituent. 



Clover sown with wheat gave a much larger yield than that seeded 

 with oats. 



Experiments with barley at Miistiala, 1892, G. Grotenfelt 

 {^[ustiaIa Agl. College Rpt. 1892^ pp. 104-100). — Analyses are given of 3 

 varieties of barley seeded and of the crops grown from the same, as

Similar differences in the composition of the seed and the product 

 obtained are found here, as in case of the oat-culture experiments

Synopsis. — Tests of fertilizers and of varieties. Nitrogen in every form and at the 

 rate of 18 and ;:i6 lbs. per acre largely increased the yield of corn. Cotton- 

 seed meal and cotton seed are recommended as the cheapest forms. The 

 increase with phosphoric acid was very slight. Potash in every form and 

 amount decreased the yield. Fractional applications of fertilizers slightly 

 increased the yield resulting from a single application. The yields of 28 

 varieties are tabulated, Virginia White Gourd Seed leading. 



In a special nitrogen experiment occupying 40 plats nitrate of soda, 

 sulphate of ammonia, dried blood, fish scrap, cotton-seed meal, crushed 

 cotton seed, green cotton seed, compost, and rotted cotton seed were 

 compared. The quantities of nitrogen used per acre were 18 and
