*In estimating the amount of manure produced it was assumed 

 that the animal under one year of age produced 20 pounds per 

 day for 180 days; that the yearling produced 25 pounds per 

 day for a year; and that the two year old steer and the cow 

 each produced 30 pounds per day. The price of manure, $1.25 

 a ton, is an assumed one, as there was no way to determine its 

 exact value. But, judging from the many tests that have been 

 made at Stations, the above value is a very conservative one. 

 For instance, as quoted in the introduction, the Ohio experiments 

 show raw manure to be worth $3.35 a ton when placed under 

 the crops mentioned; when the manure was treated with a phos- 

 phorous carrier, its value was raised to $4.88 a ton. There was 

 a difference, though, between the Ohio manure and the manure 

 secured in the above tests; the Ohio manure was collected in the 

 winter time when grains and hays were fed. It was a richer 

 manure than that made during the summer months in this test, 

 but probably no richer than the Alabama manures made during 

 the winter months.
