FERTILIZERS.

althougli there was litlle difference in effect between the three kinds. 

 "For the year 1893, when the effect of the previous application was 

 under test, sheep manure gave a larger yield than the other manures." 



Solid manure alone proved inferior to the mixed solid and liquid 

 excrement on the same crops. 



As in previous trials on the sandy loam soil of the station, nnfer- 

 mented manure gave better results than fermented. 



Fertilizer experiments at Mustiala Agricultural College during 

 1892, A. RiNDELL {Mustiala Agl. College Bpt. 1802, pp. l-21).~Experi- 

 ments with Minit. — Hay and oats were grown on eighth and quarter 

 acre plats fertilized with Thomas slag and varying quantities of kainit, 

 one plat in each series being left unfertilized. Taken 20 cm. deep the 

 soil on the plats weighed 1,492,800 kg. per hectare (1,330,000 lbs. per 

 acre), 721,080 kg. of which was dry substance. The latter contained 

 64,53 per cent mineral matter, 1.058 per cent nitrogen, 0.074 per cent 

 phosphoric acid, 0.770 per cent lime, and 0.139 per cent potash. The 

 yields obtained were very low for both crops, and the application of 

 fertilizers was not profitable in case of the hay. With the oats, how- 

 ever, the fertilizers gave a profit owing to the higher money value of 

 the crop. The oats lodged where the heavier kainit fertilization was 

 applied, but it is believ^ed this may be remedied by the addition of 

 more slag. 



Experiments tcith hone meal and Thomas slag. — Taken 20 cm. deep the 

 soil on the plats used for these experiments weighed 1,007,600 kg. per 

 hectare (807,720 lbs. per acre), 430,400 kg. being dry substance. The 

 latter contained 46.62 per cent of mineral matter, 1.567 i^er cent of 

 nitrogen, 0.008 per cent of phosphoric acid, 0.088 per cent potash, and 

 1.130 per cent lime. Oats were used for the experiments, bone meal 

 and Thomas slag being compared with one another when applied with 

 kainit. Besides Thomas slag and kainit two plats received "sugar 

 skimmings" in such quantities that the nitrogen supplied equaled that 

 of the bone meal. The summer of 1892 was unfavorable to crops, 

 heavy rains causing the oats to lodge in many places. The main 

 results obtained are given in the following table, each figure given 

 being the average for two plats.
