136 EXPERIMENT STATION RECORD. [Vol.40 



Experiments wore conducted each year also on meadows, hut these tests were 

 not so numerous as those with oats. Sewage was used at the rat 000 



liters per hectare either alone or with 300 kg. of superphosphate. The com- 

 mercial fertilizer application employed consisted of either 100 or 200 kg. of 

 nitrate of soda with .°.<hi kg. of superphosphate and 200 kg. of potash salt per 

 hectare. These meadow "tnprised mossy and swampy soils and soils of 



mineral origin. 



The results of hoth series of tests are erivon in tahles. As compared with the 

 check tests, the commercial fertilizer application showed an Increase in the 

 yield of oats as preen forage valued at 106.95 kn I), and the use of 



manure and phosphate pave an !n< valued at 67.15 krones per hectare. 



The use of the manure and phosphate showed practically the same results as 

 douhle tlie quantity of manure applied alone. In the meadow experiments, the 

 commercial fertilizer application showed a better result in each test than v 

 ohtained from the treatment with sewage. The use of 100 kg. of nitrate of BOda 

 in the application on swampy and mossy soils showed much larger Increases in 

 yields than the similar use of 200 kg. on the soils of mineral origin. SU] 

 phosphate applied with sewage was followed by an Increase In the hay yield 

 throughout the tests, but on the mineral soils the Increase was in general in- 

 adequate to be profitable the first The incn ecured on the swampy 

 and mossy soils gave B SI tory net profit.

 As compared with results of a previous experimei I on heavy soil, it is pointed 

 out that on the light soils the number of seeds producing plants was the greater 



by 2o per cent but that, in general, winter Injury W .iter on th< 



soils. 



\ study was made of the behavior of the different species, and the result 

 the observations are noted. Black medic proved uncertain in yielding capacity, 



and throughout added comparatively little to the returns. Bird-foot clover 



was found also of mediocre value, and alfalfa did not make satisfactory growth 

 Under the conditions. Italian rye crass failed to thrive properly on light soil, 

 but English rye grass was one of the best-yielding - in the test Field 



brome grass also produced n large proportion of the total yield. Tall oat lt' 

 did not seem adapted to mixed culture with English rye crass and field brome 

 Crass. Timothy gave much better results than tall oat crass, and where liquid 

 manure was applied cave specially pood returns the second and third ye 

 Meadow fescue Increased the yield of hay but slightly, and hard • which 



withstood dromrht and made a fair growth on poor soils, proved too low in 

 quality to make a valuable constituent of the meadow plant mixture. 



ANike clover, white clover, bird foot clover. English ry. orchard
